True Evangelisation: The Apostolate of the Transformed Heart

The Holy Spirit Master of Evangelisation

“The Holy Spirit is indeed the principal agent of the whole of the Church’s mission. His action is preeminent in the mission ad gentes …” — John Paul II, Redemptoris Missio § 21

“… in and through [the apostles and the Church] the Holy Spirit remains the transcendent and principal agent for the accomplishment of this work in the human spirit and in the history of the world.” — John Paul II, Redemptoris Missio § 21

“[For] our time … the Spirit is the principal agent of the new evangelization …” — John Paul II Letter to Priests 1998

Sanctification or Charisms?

The Holy Spirit sanctifies: “This is the will of God, your sanctification” (1 Thessalonians 4:3), and “God chose you from the beginning to be saved through sanctification by the Spirit” (2 Thessalonians 2:13).

The Holy Spirit also offers charisms for the Church: “To each is given the manifestation of the Spirit for the common good” (1 Corinthians 12:7).

Sanctification is about our personal growth, purification, and transformation in Jesus: “We all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image” (2 Corinthians 3:18).

Charisms, by contrast, are given for the service of our brothers and sisters in the Church: “Since you are eager for manifestations of the Spirit, strive to excel in building up the Church” (1 Corinthians 14:12).

Charisms in themselves are not a sign of holiness; they do not sanctify. As St Paul warns, it is possible to have extraordinary gifts without charity and therefore without holiness: “If I speak in the tongues of men and of angels … and if I have prophetic powers … but have not love, I am nothing” (1 Corinthians 13:1–2).

Their exercise, however, when carried out in obedience, does sanctify: “Obey your leaders and submit to them, for they are keeping watch over your souls” (Hebrews 13:17). Obedience unites the exercise of charisms to charity, and therefore to sanctification.

What is the relationship between the two actions of the Holy Spirit in us?

When Jesus spoke of power over the devil, he stated plainly that the devil cannot be cast out without prayer and fasting: “This kind cannot be driven out by anything but prayer and fasting” (Mark 9:29). Prayer yes, but what kind of prayer?

When the disciples returned from their evangelising mission, he invited them to rejoice not because the devil was subject to them but because their names were written in heaven, that is, because they were being sanctified: “Do not rejoice in this, that the spirits submit to you; rather rejoice that your names are written in heaven” (Luke 10:20).

He also said that one day people would approach him claiming to have cast out devils in his name, preached in his name, and worked miracles in his name, yet he would send them away: “Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ And then I will declare to them, ‘I never knew you; depart from me’” (Matthew 7:22–23). This means that they were not doing his will, were not listening to him, were not sanctified.

When Jesus was questioned about fasting, he explained the deep meaning of Christian fasting as the quest and search for the bridegroom: “Can the wedding guests mourn as long as the bridegroom is with them? The days will come when the bridegroom is taken away from them, and then they will fast” (Matthew 9:15). In this sense, Jesus brings together fasting and prayer: the physical effort and sacrifice with the spiritual effort. He never separated them.

In fact, what truly moves things, what brings real change, is God’s action in the soul — the action of the Holy Spirit. So the crucial question is how we can receive this action of the Holy Spirit. Is it possible to “have” the Holy Spirit, to “have” his action in us and through us? This is the core of evangelisation.

To “have” the Holy Spirit, to allow his action to work in us and through us, we need to be transformed, so that the work of the Holy Spirit becomes a harmonious cooperation between him and us. The first necessity, the first need, is to be transformed and purified, so the Holy Spirit can truly take a deeper hold, so to speak, of our soul and spirit. The Holy Spirit is not merely a gift given to us as something separate from our sanctification. The action of the Holy Spirit can only take place if sanctification and transformation are occurring, so that it becomes a genuine collaboration and not a mere puppet-like instrumentality in his hands.

The tendency at times, when we speak of the Holy Spirit, is to focus on the charisms or “talents” as we call them today, and to forget that working with the Holy Spirit is not mechanical, not puppet-like. It is collaboration, transformation. As the Lord himself puts it: “I have called you friends, because I have made known to you everything that I have heard from my Father” (John 15:15). This carries the clear implication of the need to be transformed.

So when we consider the Holy Spirit, we must look to him as the one who sanctifies and transforms us, and therefore seek the best means to be transformed and to make acts of love that come from him, with his help and his transforming action in us. Otherwise, if we focus on the charisms apart from our personal transformation, we are in a sense disobeying the Holy Spirit. We are putting ourselves outside his principal work, because the Holy Spirit’s primary mission is to sanctify us, not to distribute charisms or talents. The main power of evangelisation, the essence of being witnesses, arises from the fact that we are transformed. It comes from within. It is not an external addition, not something we do regardless of our state of transformation and sanctification.

The Power of Evangelisation and its fruitfulness

The Higher Way

Saint Paul says, “And I will show you a still more excellent way” — hodòn kath’ hyperbolēn — in 1 Corinthians 12:31. The “more excellent way” is then explained immediately in the following chapter: it is the way of love (agapē). In other words, the “higher way” is the path of charity, which surpasses all charisms and gives them their proper meaning. Saint Paul makes this unmistakably clear as he opens the next chapter: “If I speak in the tongues of men and of angels, but have not love, I am a noisy gong” (1 Corinthians 13:1). So the “higher way” is love as the form of all holiness and the measure of every spiritual gift.

But what is this love — this charity — this action of the Holy Spirit in us and through us, poured out upon the Church and the world?

If we truly desire to help our brothers and sisters, we must understand that it is the quality of the Fire of God within our hearts that makes the difference and brings about change. This Fire is God’s charity dwelling in us. The Holy Spirit purifies and transforms us, filling and enkindling our hearts with this divine fire. In cooperation with us, the Holy Spirit then sends forth flares of this fire. These divine flares are what aid and uplift our brothers and sisters.

It is a love of an entirely different order. When the spirit is thoroughly purified and transformed, the Holy Spirit is free to act. In this state, the person loves God with God’s own love; the soul gives the Holy Spirit to God, and, also, gives the Holy Spirit to others. (See below)

Thérèse, the Holy Spirit and the Church

In her retreat of September 1896, Thérèse was given the grace of seeing the relationship between the Holy Spirit (his charity in us, Love) and the Church. She explains her grace in the Manuscript B. In a way it is a grace about evangelisation, about the salvation of the souls and about the work of Evangelisation. She calls it “my vocation”, but it should be seen as the common denominator of all vocations, it is the fundamental Marian dimension of evangelisation. To illustrate the grace she received, the grace of seeing the relationship between the Holy Spirit and the Church she says “I understood that Love alone made the members of the Church act, that if Love were to be extinguished, the Apostles would no longer proclaim the Gospel, the Martyrs would refuse to shed their blood…” (Ms B 3v°).

Note: The term “Love” here should be understood in the light of our study on the flares of Saint John of the Cross (see below). What then will she do, she who cannot perform striking deeds, cannot preach the Gospel, nor shed her blood? She will love on behalf of her brothers who are fighting (cf. Ms.B 4r°). One must recognise in this “she will love” all the powerful fruitfulness contained in the flares of the Holy Spirit described by St. John of the Cross in the Living Flame of Love! She will love, “she will give God, one could say, to whomever it pleases her.” (Living Flame B, 79)

The next step then is to “acquire” this love, to be moved by it. Let us not forget the fundamental role the Act of Oblation plays in her life and his continuation in the story of the little bird in Ms B. As a consequence, she will be feeding the Church, the members of the Church, with this love. Her “pumping” this love will help the Church, will save souls, will help the Holy Spirit work in the souls. In one word, this is the foundation of the work of Evangelisation, this is the marian way of accomplishing it. She lives under Mary’s Veil, and what did Mary do in Pentencost, and after Pentecost? she interceded, she pumped the Holy Spirit to the Church. “While it is an historical fact that the Church came forth from the Upper Room on the day of Pentecost, in a certain sense one can say that she has never left it. … The Church perseveres … with Mary, the Mother of Christ … praying in the Upper Room.” (John Paul II, Dominum et Vivificantem, 66)

Therese says then that she found her vocation, her function in the Church, in the heart of the Church (the upper room with Mary?) she will be Love, this love we are talking about. Putting herself under the direct action of the Holy Spirit – implicitly with Mary – has a double effect: 1- loving God as He loves her, loving God with the Love (the Holy Spirit) he loves her with, ie giving God to God (see below) and 2- Giving God to whoever she wants, whoever Mary wants (see below St. John of the Cross explanation of the Flares of the Holy Spirit), which is like pumping the Holy Spirit to the entire Church, to the souls to be saved.

It is of the highest importance to understand this moment in Therese’s live and its repercussions on the life of the Church, in fact Therese is Doctor of the Church, like St. John of the Cross, she embodies his teaching in simplicity and in perfection. Her doctorate, her teaching, is a teaching by example: she lived to the fullness what St. John of the Cross says in the Spiritual Canticle and in the Living Flame of Love. We need to give a great attention to two aspects which proceed from this grace she receives and lives and its direct effect on Evangelisation and deeper understanding of the main work of the Holy Spirit in our life. The grace she received is for the entire Church and serves as a foundation for Evangelisation and for understanding how the Holy Spirit works.

Therese says: “I understood that Love alone made the members of the Church act, that if Love were to be extinguished, the Apostles would no longer proclaim the Gospel, the Martyrs would refuse to shed their blood…” (Ms B 3v°). Thus, if she wished to exercise any influence within the Church, she needed to attain this quality of love. She wrote: “With what desire and consolation I repeated to myself, from the very beginning of my religious life, these other words of N.P. Saint John of the Cross: ‘It is of the utmost importance that the soul exercise itself greatly in Love, so that, consuming itself swiftly, it scarcely lingers here below but arrives promptly to see its God face to face.’” (Therese of the Child Jesus, Yellow Notebook 27.7.5) This exercise of Love is first and foremost the perfect love of our neighbour, a love in which our feelings and emotions do not interfere, as taught by Saint Teresa of Avila (see in Way of Perfection her explanation of perfect love). In a certain sense, this love also incites God to love us more (cf. John of the Cross, Spiritual Canticle A,12,11).

“At this point it should be noted that God places His grace and His love in the soul only according to the will and love of the soul. It is therefore necessary for the true lover to ensure that this is not lacking, since by this means, (as we have said), he will incite God to love him more — if it may be said thus — and to delight in his soul. And to continue this charity, it is necessary to practise and exercise what the Apostle says: ‘Love is patient, love is kind, it is not envious, it does not brag, it is not proud, it is not self-seeking, it is not easily angered, it keeps no record of wrongs, it does not delight in evil but rejoices in the truth, it always protects, always trusts, always hopes, always perseveres’ (1 Cor 13:4-7).” (C.S.A. 12,11)

Let us see how St. John of the Cross explains in the Living Flame these two incredible acts: the soul transformed in the Holy Spirit is capable with the Holy Spirit to 1- Love God as she is loved by Him (to Give God (the Holy Spirit) to God) and to 2- Give God to whoever she wants.

a) Giving God to God

It is of the highest importance to give God to God, to love God as we are loved by Him. This incredible perspective is affirmed and explained by St. John of the Cross and mentioned by St. Therese as a result of her reading of St. John of the Cross. These acts of giving God to God, of Loving God with his own love are performed by these Flares of the Fire of the Holy Spirit, and are described in details by St. John of the Cross in his major work: Living Flame of Love.

In these acts, the gift that the soul makes to God is complete, as he himself will say. The soul can give nothing more. It is here that we understand the greatness of God’s Gift: He gives to the soul the ability to give Him to Himself. He entrusts Himself to her, He entrusts the Son to her, and she offers Him as if He were her own personal possession. The soul is truly royal when it reaches these exchanges. Let us listen to the St. John of the Cross: “[The soul] gives God to God Himself in God (darsele a si mismo). And this is the complete and true gift that the soul makes to God. The soul sees here that truly God belongs to her and that she possesses Him by hereditary possession and with property by right, as an adopted child of God, through the grace that God has granted her of giving Himself, in her, to Himself, and that she can dispose of Him as her own and voluntarily give Him to whomever she pleases; and thus, she gives Him to her Beloved, who is God Himself who has given Himself to her — in doing this, she repays God all that she owes Him, since of her own free will she gives Him as much as she receives from Him.” (St. John of the Cross, Living Flame III,78)

Note: darsele a si mismo Translating this Spanish shorthand is difficult. None of the translators have succeeded in rendering it. A literal translation would be: “the grace that God has granted her of giving Himself to her to Himself,” which would mean that God gives the soul the ability to give herself to Him while He gives Himself to Himself. In other words, He gives the soul to be in the Son who gives Himself to Him. This corresponds perfectly to what the Saint says a few lines earlier: “she does in God, through God, what God does in her by Himself” (Ibid.); she acts (she offers the Son to the Father) in God the Trinity, through God the Son, in the same way that He acts (by giving Himself to the Father) in her by Himself. Or again: “she gives God to God in God” (Ibid.), she gives the Son to the Father, within the Trinity.

The Soul gives the Holy Spirit to the Father “as a thing of her own and with a voluntary offering, so that He may love Himself in Him as He deserves […].” (LF III,79) And here is a passage in which the Saint expresses, in another way, her possession of God: “And thus, a mutual love is established between God and the soul, in conformity with the union and gift of marriage, in which both together possess the goods of the other, which consist in the divine essence, each of them possessing them freely, because of the voluntary gift they have made of them to one another, saying to one another what the Son of God said to His Father in Saint John: […] All my goods are Yours, and Yours are mine, and I am glorified in them [Jn 17:10].” (LF III,79) We can sense the delight she receives from all of this!

In these flares, the soul “gives God to God,” according to the Saint’s expression. The fact that the soul is, in its very being, transformed into God results in this capacity to participate in the very work of God, in God. She gives the Holy Spirit to God, a perfect work that eases her heart and allows her to render to God Love for Love (St. John of the Cross, S.C.A. 9,6). Saint Thérèse of the Child Jesus says: “O Jesus, I know it, love can only be repaid by love; therefore I have sought and found the means to ease my heart by giving You Love for Love.” (Story of the Soul, Manuscript B 4r°) Does the Saint not say that the action of these flares repays every debt? (cf. LF II v.5)

“And just as in this gift that the soul makes to God, she gives Him the Holy Spirit as a thing of her own and with a voluntary offering, so that He may love Himself in Him as He deserves, she receives an inestimable contentment and enjoyment, because she sees that she gives to God something which is hers by right, and which, nevertheless, is proportioned to the infinite being of God.
For, although it is true that the soul cannot give God anew to God Himself, since in Himself He is always the same, yet she does it of herself perfectly and truly, in giving Him all that He had given her in order to repay love — which is accomplished in giving as much as one receives; and God repays Himself with this gift of the soul, for otherwise He would not repay Himself any less, and He is grateful to the soul, as to something she gives of herself, so much so that, on the occasion of this very gift, the soul loves Him as if anew.” (LF III,79)

b) The Value of These Acts for the Church

Since these acts are performed in God (with God), by God, and according to God’s very mode, it is as if God Himself were performing them. They have infinite value. Every act of charity that Christ performed in His life is infinite. Saint Thomas Aquinas even states that He could have saved humanity by a single one of these acts (cf. Summa Theologica IIIa q.48 a.1). We can begin to grasp the value of such acts for the salvation of humanity.

Let us see what St. John of the Cross says about the smallest movement of pure love and its effect on the Church. St. Therese will read it and be very much influenced by this teaching (See Story of the Soul, Ms. B 4v°: “O my Jesus! I love You! I love the Church, my Mother! I recall that “the smallest act of PURE LOVE is of more value to her than all other works together“). Here it is:

“In truth the soul is now lost to all things, and gained only to love, and the mind is no longer occupied with anything else. It is, therefore, deficient in what concerns the active life, and other exterior duties, that it may apply in earnest to the one thing which the Bridegroom has pronounced necessary; (Luke 10:42) and that is waiting upon God, and the continuous practice (exercise) of His love. So precious is this in the eyes of God that He rebuked Martha because she would withdraw Mary from His feet to occupy her actively in the service of our Lord. Martha thought that she was doing everything herself, and that Mary at the feet of Christ was doing nothing. But it was far otherwise: for there is nothing better or more necessary than love. Thus, in the Canticle, the Bridegroom protects the bride, adjuring the daughters of Jerusalem—that is, all created things—not to disturb her spiritual sleep of love, nor to waken her, nor to let her open her eyes to anything till she pleased. “I adjure you, O daughters of Jerusalem, that you do not stir up, nor awake my beloved till she please.” (Cant. 3:5)

2. Observe, however, that if the soul has not reached the state of unitive love, it is necessary for it to make acts of love, as well in the active as in the contemplative life. But when it has reached it, it is not requisite it should occupy itself in other and exterior duties—unless they are matters of obligation—which might hinder, were it but for a moment, the life of love in God, though they may minister greatly to His service; because an instant of pure love (un poquito de este puro amor) is more precious in the eyes of God and the soul, and more profitable to the Church, than all other good works together, though it may seem as if nothing were done. Thus, Mary Magdalene, though her preaching was most edifying, and might have been still more so afterwards, out of the great desire she had to please God and benefit the Church, hid herself, nevertheless, in the desert thirty years, that she might surrender herself entirely to love; for she considered that she would gain more in that way, because an instant of pure love is so much more profitable and important to the Church.

3. When the soul, then, in any degree possesses the spirit of solitary love, we must not interfere with it. We should inflict a grievous wrong upon it, and upon the Church also, if we were to occupy it, were it only for a moment, in exterior or active duties, however important they might be. When God Himself adjures all not to waken it from its love, who shall venture to do so, and be blameless? In a word, it is for this love that we are all created. Let those men of zeal, who think by their preaching and exterior works to convert the world, consider that they would be much more edifying to the Church, and more pleasing to God—setting aside the good example they would give—if they would spend at least one half their time in prayer, even though they may have not attained to the state of unitive love. Certainly they would do more, and with less trouble, by one single good work than by a thousand: because of the merit of their prayer, and the spiritual strength it supplies. To act otherwise is to beat the air, to do little more than nothing, sometimes nothing and occasionally even mischief; for God may give up such persons to vanity, so that they may seem to have done something, when in reality their outward occupations bear no fruit; for it is quite certain that good works cannot be done but in the power of God. O how much might be written on this subject! this, however, is not the place for it.” (Spiritual Canticle B, Stanza 29, Introduction)

This is what St. Therese will seek through her Act of Oblation: “In order to live in a pure act of love…” (See Act of Oblation). St. John of the Cross will return to this point in the Living Flame of Love: “Therefore, these acts of love are of very great worth, and the soul merits more in one of them, and this act is worth more than all that she had done throughout her life without this transformation — whatever it may have been.” (LF I,3)

It should be noted that this remark of the St. John of the Cross sheds a singular light on the problem of apostolate and evangelisation. One thus understands his tireless insistence, throughout his works, on urging the soul towards the highest peaks. The good that results from this for the Church is immense.

Let us now admire what St. John of the Cross says about the purified soul, her dignity and power, and the consequences for the Church and Evangelisation:

“Returning, then, to our explanation, the soul here knowing that all has turned out well for it, and that now sicut tenebrae eius ita lumen eius (Ps 138:12), and that, as it was a participant in the tribulations, so now it is in the consolations and in the kingdom (2 Cor 1:7), having been very well repaid for its interior and exterior labours with divine goods of the soul and of the body, without there being any labour that does not have its corresponding great reward, it acknowledges it as now well satisfied, saying: “And every debt paid,” giving thanks to God in this verse, as David also did in his own (Ps 70:20–21) for having been brought out of his trials, saying: “How many tribulations thou didst show me, many and evil, and from all of them thou didst deliver me; and from the depths of the earth thou didst bring me up again; thou didst multiply thy magnificence, and turning to me, thou didst console me!”
And thus this soul, which before it arrived at this state was sitting outside, like Mordecai at the gates of the palace, weeping in the squares of Susa over the danger to its life, clothed in sackcloth, unwilling to receive the garment of Queen Esther, nor having received any reward for the services it had rendered to the king and for the faith it had shown in defending his honour and life, in one day, as happened to Mordecai himself, all its labours and services are here repaid, causing it not only to enter within the palace and to stand before the king clothed with royal garments, but also that the crown and sceptre and royal seat be given to it, with possession of the king’s ring, so that everything it wishes it may do, and what it does not wish it need not do in the kingdom of its Bridegroom (Esth chs. 4–8), for those of this state obtain all that they desire.
In all this not only is it repaid, but even its enemies the Jews are put to death, who are the imperfect appetites that were taking away its spiritual life, in which now it lives according to its powers and appetites.” (Living Flame, 31)

Here are the consequences. In the silence of the inner spiritual exercise of love the soul gives God to whomever it willingly desires:

“Because there the soul sees that truly God is its own, and that it possesses Him with hereditary possession, with rightful ownership, as an adopted son of God, through the grace that God granted it of dársele a sí mismo, and that, as something belonging to it, it can give and communicate Him to whomever it willingly desires.” (Living Flame 78)

One can only stand in utter awe before the work of the Holy Spirit and what He desires to accomplish in us. Blessed be God, who has taught us all this through Saint John of the Cross and Saint Thérèse of the Child Jesus!

Note: It is very important to pursue the development of this teaching, which can be found in this article: Mary’s Fiery Prayer.

Conclusion

Seeing all that the Holy Spirit desires to accomplish in us through His ordinary work of sanctification, we begin to perceive the marvels that flow from purification and transformation into Him — how the soul cooperates with Him, placing its hands in His, so to speak, in the work of evangelisation, sanctification, and salvation within the Church and throughout the world. No charism can reach such a level. And with this, we understand more clearly Our Lady’s work, and how every Christian is called to join her in the Upper Room to take part in this fundamental work of the Holy Spirit.

From Transformation to Mission: A Theological Perspective

In the classic and fully Catholic understanding of synergy with the Holy Spirit, the key point is: the Spirit’s action in us is inseparable from our sanctification. God does not act on us as on puppets; He acts with us, in us, through a transformed heart.

1. The Holy Spirit’s Action Requires Inner Transformation

It is absolutely foundational in Scripture and Tradition that to “have” the Holy Spirit in a fruitful way presupposes purification, conversion, and transformation. This is not because God is reluctant, but because the Spirit is personal and seeks cooperation, not mechanical manipulation. St Paul lays out the principle very plainly: “Do not be conformed to this world, but be transformed by the renewal of your mind” (Romans 12:2). He is saying that transformation is the precondition of discernment and of cooperating with God’s will. Likewise, in 2 Timothy: “If anyone purifies himself from what is ignoble, he will be a vessel for noble use, consecrated and fit for the Master” (2 Timothy 2:21). Paul’s image is precise: purification makes us usable. God’s action and our sanctification are not two separate tracks; they are one movement.

2. The Spirit’s Action and Our Purification Are Inseparable

The Catechism expresses this unity beautifully: “The Holy Spirit is the master of the interior life. By his action, he purifies us, enlightens us, and transforms us” (CCC 1999; see also CCC 1988).

And again: “The Holy Spirit makes us spiritual by the transformation of our hearts” (CCC 1989).
Let us notice the interplay: the Spirit transforms us, but He also expects our cooperation. Sanctification is not an external varnish. It is the condition under which His action becomes stable, deep, and fruitful. St John of the Cross is even more radical. He says that God can only unite Himself to a soul that has been purified to the degree of union: “The soul must be purified and emptied of all that is not God… for the divine union to be wrought” (“Ascent of Mount Carmel,” II.5). The Spirit is not “given” in a way that bypasses purification. The Spirit creates purification so that He can act more freely.

3. True Cooperation vs. Being a Mere Instrument

It is important to insist that the Holy Spirit does not want to make us passive instruments. Scripture is again explicit about this. Paul says: “We are God’s co-workers” (1 Corinthians 3:9). The Greek term is συνεργοί — literally “synergoi”. The Church’s entire mystical and ascetical tradition is built on this word: synergy. Synergy means: God acts, We act, And the result is a shared action. Not because God needs us, but because He created us for communion, not for puppetry.

The Council of Trent teaching on justification says the same: “God touches the heart of man through the illumination of the Holy Spirit… yet man is not passive… he freely assents and cooperates with that grace” (DS 1525). This is a mature doctrine: the Spirit’s power is given in proportion to our capacity to cooperate. And that capacity grows only through purification.

4. Sanctification as the Condition for Evangelisation and Power

Jesus does say that certain powers (especially over the demonic) require prayer and fasting (Mark 9:29). The Fathers understood this as meaning: the Spirit acts more freely in a purified vessel. St Basil says: “The Spirit rests in the purified soul… and manifests Himself according to the measure of purification.” (“On the Holy Spirit,” ch. 9). This is exactly the point: the measure of purification is the measure of cooperation. For evangelisation, this is crucial. Before mission comes transformation. As Pope Benedict XVI writes: “The Church does not grow by strategies, but by holiness… evangelisation requires docility to the Spirit, which is born of continual conversion.” (“Deus Caritas Est,” 31).
Holiness is the widening of the soul so the Spirit can act. Nothing in evangelisation replaces this.

5. The Core Principle

To put it in a single line, perfectly aligned with the tradition: The Holy Spirit acts in us to the degree that we consent to be purified, transformed, and made capable of cooperating with Him. God does not overpower us. He transforms us so that His action becomes ours, and our action becomes His. This is why spiritual formation is not optional. Without radical inner change, the action of the Holy Spirit remains partial, fragile, and often blocked. With it, evangelisation becomes fire.

The Holy Spirit Sanctifier

Sanctification is the beating heart of the Church’s teaching on the Holy Spirit. Temptation to focus on “talents,” “charisms,” or “effects,” instead of the inner transformation gets right to the critical distortion that so often sneaks into contemporary spirituality. Let us see this in Scripture and Tradition.

1. The Holy Spirit Is First the Sanctifier, Not the Supplier of Talents

The Catechism says it without varnish: “The Holy Spirit is the master of the interior life.” (CCC 1995) His primary mission is to sanctify, not to decorate us with abilities. Charisms are real, but they are secondary and subordinate to holiness. St. John Chrysostom captures the danger very bluntly:

“To have gifts is nothing; what is required is purity of life.” (“Homilies on 1 Corinthians,” Hom. 29)

The early Fathers always put holiness before power. Because holiness is the true power as we saw above with St. John of the Cross.

2. Jesus Himself Defines the Relationship: Not Servants, but Friends

Here is a key Johannine line: “I do not call you servants any longer… I have called you friends” (John 15:15). A friend is someone who knows the heart of the Lord, not just the tasks. Friendship with Jesus implies transformation, because friendship is reciprocal; we must be made capable of that intimacy. St Augustine comments: “We are not to be servants, but friends; and friends not by nature but by being transformed through grace.” (“Tractates on John,” 85.2) The point is: the Spirit’s action is personal; He forms friends of God, not instruments.

3. Charisms Without Transformation Are Spiritually Empty

Again, let us remember that St. Paul makes this point with astonishing clarity in 1 Corinthians 13: “If I have prophetic powers… but do not have love, I am nothing.” (1 Corinthians 13:2) “Nothing” — not “less helpful,” but nothing. Paul is blunt: gifts without transformation = zero. The Church Fathers read Paul exactly this way. Origen writes: “The Spirit distributes gifts, but He dwells only in the purified.” (“Commentary on Romans,” II.11) Charisms can be given temporarily even to imperfect souls, but indwelling — the real fruitfulness — requires purification.

4. True Evangelisation Flows from Who We Become, Not What We Can Do

The main work of witness comes from within. This is pure Pauline theology. St Paul again:

“We all, with unveiled faces, beholding the glory of the Lord… are being transformed into the same image from glory to glory. This comes from the Lord, the Spirit.” (2 Corinthians 3:18) Evangelisation is not first about doing; it is about becoming. The more we are transformed into Christ, the more Christ radiates through us. Pope Benedict XVI summarises this perfectly:

“The Church does not grow by proselytism but by attraction.” (“Deus Caritas Est,” 31) Attraction comes from holiness, from the radiance of a life transformed by the Spirit.

5. Ignoring Personal Transformation Is a Subtle Form of Disobedience

Here is something very delicate: focusing on charisms without purification is, in effect, stepping outside the Spirit’s principal intention. St Basil is explicit on this point: “The Spirit is resisted not when His gifts are neglected, but when His work of sanctification is despised.” (“On the Holy Spirit,” ch. 16) To seek gifts without sanctification is to want the Spirit’s “tools” without His heart.

It is also dangerous. St John of the Cross cautions: “Any desire for spiritual gifts not grounded in humility and purity is an obstacle to union with God.” (“Ascent of Mount Carmel,” III.46) When the main work of the Spirit — our sanctification — is sidelined, the whole spiritual life becomes unstable.

6. The Spirit Works Through Love, Not Just Power

The need to make acts of love that come from the Holy Spirit with His help is vital. This is deeply traditional. St Thomas Aquinas says: “Charity is the form of all the virtues, because it is by charity that the Holy Spirit forms us from within.” (“Summa Theologiae,” II-II, q. 23, a. 8) The Spirit’s work is primarily the shaping of charity — and it is from charity that all fruitful evangelisation flows.

7. In Summary

The Holy Spirit’s main work is sanctification.

Charisms are secondary and function properly only when rooted in holiness.

Evangelisation is the overflow of inner transformation, not an external performance.

Friendship with Christ requires our purification.

Cooperation with the Spirit means embracing His work in us, not chasing His effects around us.

Charisms without sanctification are noise.

Sanctification without charisms is already fruitful.

When the two come together in the right order, the Church burns with apostolic fire.
