We ask the Holy Spirit to set us free from sin, to make us just with God, to enable us to live in truth, justice, love

At the General Audience, on Wednesday, 4 Decem­ber, in the Paul VI Audience Hall, the Holy Father commented on Psalm 50[51], the Miserere, a heartfelt plea for God's mercy and forgiveness. The Psalmist, acknowledging his sin, asks God to create in him a pure heart and grant him a steadfast spirit. He prays: "Do not deprive me of your holy spirit" (Ps 50[51],13). The Church sees in these prophetic words a reference to the gift of the Holy Spirit, who sets us free from sin, makes us a new creation, and enables us to live in truth, justice and love. The promise of this spiritu­al rebirth leads the Psalmist to bear joyful witness to the justice of God, who shows mercy to sinners and restores them to grace, freedom and new life. Here is a translation of the Holy Father's catechesis n. 60. Af­ter the commentary, the Holy Father greeted the pil­grims in the major European languages. To the Polish group, the Pope expressed his thanks for the excellent organization of his August visit. At the end of the au­dience, the Holy Father issued a stirring appeal for civil harmony and peace in Venezuela.

Brothers and Sisters,
1. Every week the Liturgy of Lauds repeats Psalm 50[51], the famous Mis­erere. We have already reflected on sec­tions of it on other occasions. Now also, we will reflect in a particular way on a section of this grandiose plea for for­giveness: verses 12-16.

Triple invocation of the Spirit

First of all, it is important to note that in the original Hebrew the word "spirit" is repeated three times, invoked of God as a gift and received by the hu­man creature who has repented of his sin: "Renew in me a steadfast spirit.... Do not deprive me of your holy spirit.... Sustain in me a generous spirit" (vv. 12.13.14). One could say, taking re­course to a liturgical term, that it is an "epiclesis", that is, a triple invocation of the Spirit who, as in creation hovered over the waters (cf. Gn 1,2), now pene­trates the soul of the faithful, infusing it with new life and raising it from the kingdom of sin to the heaven of grace.

Spirit in the human soul

2. The Church Fathers, in the "spirit" invoked by the Psalmist, see the effec­tive presence of the Holy Spirit. Thus, St Ambrose is convinced that it is about the Holy Spirit, who is one "who was active in the prophets, was breathed up­on the Apostles and was joined with the Father and the Son in the sacrament of Baptism" (Lo Spirito Santo I, 4, 55: SAEMO 16, p. 95; The Holy Spirit in St Ambrose, Theological and Dogmatic Works, CUA Press, reprinted 1977). The same conviction is expressed by other Fathers, such as Didymus the Blind of Alexandria, Egypt, and Basil of Cae­sarea in their respective treatises on the Holy Spirit (Didymus the Blind, Lo Spi­rito Santo, Rome 1990, p. 59; Basil of Caesarea, Lo Spirito Santo, X, 24, Rome 1993).
    
Again, St Ambrose, observing that the Psalmist speaks of the joy that invades the soul once it has received the gener­ous and powerful Spirit of God, com­ments: "Joy and delight are fruits of the Spirit and really the sovereign Spirit is the one on whom we are founded. Thus whoever is brought to life by the sovereign Spirit is not subject to slavery, is not enslaved by sin, is not indecisive, does not wander here and there, is not uncertain in his choices, but standing on the rock, he is firm with feet that do not waver" (Apologia del profeta David a Teodosio Augusto, 15,72 [Defence of the Prophet David for the Emperor Theodosius]: SAEMO 5, 129).

Spirit: inner resurrection

3. With this triple mention of the "spirit", after describing in the preceding verses the dark prison of guilt, Psalm 50[51] opens onto the bright realm of grace. It is an important turning point, comparable to a new creation. As in the beginning God breathed his spirit into matter and created the human person (cf. Gn 2,7), so now the same divine Spirit recreates (cf. Ps. 50[51],12), re­news, transfigures and transforms the repentant sinner, embraces him again (cf. v. 13) making him share in the joy of salvation (cf. v. 14). Now the human being, animated by the divine Spirit, sets out on the path of justice and love, as is said in another Psalm: "Teach me to do your will, for you are my God! Let your good spirit guide me on a level path!" (cf. Ps 142[143],10).

Thanksgiving for God's mercy

4. Having experienced this inner re­birth, the person praying becomes a wit­ness; he promises God to "teach the erring your ways" of good (Ps 50[51], 15), so that, like the Prodigal Son, they may be able to return to the house of the Father. In the same way, St Augus­tine, after experiencing the dark paths of sin, in his Confessions felt the need to witness to the freedom and the joy of salvation.

Whoever has experienced God's mer­ciful love, becomes a passionate witness of it, especially in dialogue with those who are still caught in the nets of sin. Let us think of the person of Paul, daz­zled by Christ on the road to Damascus, who became an untiring missionary of divine grace.

Justice: rehabilitation of sinner

5. For one last time, the person pray­ing looks at his dark past and cries out to God: "Free me from blood guilt, O God, my saving God (cf. NAB version of v. 16). The "blood", to which he refers is variously interpreted in Scripture. Here on the lips of King David, it refers to the killing of Uriah, the husband of Bathsheba, the woman who was the ob­ject of the king's passion. In a more general sense, the invocation indicates the desire for purification from evil, vio­lence and hatred always present in the human heart with dark and malicious force. Now the lips of the faithful per­son, purified from sin, sing praise to the Lord.

In fact, the passage of Psalm 50[51] which we have just commented on ends with the promise to proclaim the "jus­tice" of God. The term "justice" in this context, as so often in biblical language, does not actually indicate God's punitive action of evil by God, but rather indi­cates the sinner's rehabilitation, since God reveals his justice by making sinners­ just (cf. Rom 3,26). God derives no pleasure from the death of the wicked, but only that he give up his behaviour and live (cf. Ez 18,23).
