Whether grace and virtues are bestowed on man by Baptism?
Objection 1: It seems that grace and virtues are not bestowed on man by Baptism. Because, as stated above (Q 62, A 1, ad 1), the sacraments of the New Law "effect what they signify." But the baptismal cleansing signifies the cleansing of the soul from guilt, and not the fashioning of the soul with grace and virtues. Therefore it seems that grace and virtues are not bestowed on man by Baptism.
Objection 2: Further, one does not need to receive what one has already acquired. But some approach Baptism who have already grace and virtues: thus we read (Acts 10:1,2): "There was a certain man in Cesarea, named Cornelius, a centurion of that which is called the Italian band, a religious man and fearing God"; who, nevertheless, was afterwards baptized by Peter. Therefore grace and virtues are not bestowed by Baptism.
Objection 3: Further, virtue is a habit: which is defined as a "quality not easily removed, by which one may act easily and pleasurably." But after Baptism man retains proneness to evil which removes virtue; and experiences difficulty in doing good, in which the act of virtue consists. Therefore man does not acquire grace and virtue in Baptism.
On the contrary, The Apostle says (Titus 3:5,6): "He saved us by the laver of regeneration," i.e. by Baptism, "and renovation of the Holy Ghost, Whom He hath poured forth upon us abundantly," i.e. "unto the remission of sins and the fulness of virtues," as a gloss expounds. Therefore the grace of the Holy Ghost and the fulness of virtues are given in Baptism.
I answer that, As Augustine says in the book on Infant Baptism (De Pecc. Merit. et Remiss. i) "the effect of Baptism is that the baptized are incorporated in Christ as His members." Now the fulness of grace and virtues flows from Christ the Head to all His members, according to Jn. 1:16: "Of His fulness we all have received." Hence it is clear that man receives grace and virtues in Baptism.
Reply to Objection 1: As the baptismal water by its cleansing signifies the washing away of guilt, and by its refreshment the remission of punishment, so by its natural clearness it signifies the splendor of grace and virtues.
Reply to Objection 2: As stated above (A 1, ad 2; Q 68, A 2) man receives the forgiveness of sins before Baptism in so far as he has Baptism of desire, explicitly or implicitly; and yet when he actually receives Baptism, he receives a fuller remission, as to the remission of the entire punishment. So also before Baptism Cornelius and others like him receive grace and virtues through their faith in Christ and their desire for Baptism, implicit or explicit: but afterwards when baptized, they receive a yet greater fulness of grace and virtues. Hence in Ps. 22:2, "He hath brought me up on the water of refreshment," a gloss says: "He has brought us up by an increase of virtue and good deeds in Baptism."
Reply to Objection 3: Difficulty in doing good and proneness to evil are in the baptized, not through their lacking the habits of the virtues, but through concupiscence which is not taken away in Baptism. But just as concupiscence is diminished by Baptism, so as not to enslave us, so also are both the aforesaid defects diminished, so that man be not overcome by them.
III · Q. 69, Art. 5: Whether certain acts of the virtues are fittingly set down as effects of Baptism, to wit---incorporation in Christ, enlightenment, and fruitfulness?
Whether certain acts of the virtues are fittingly set down as effects of Baptism, to wit---incorporation in Christ, enlightenment, and fruitfulness?
Objection 1: It seems that certain acts of the virtues are unfittingly set down as effects of Baptism, to wit---"incorporation in Christ, enlightenment, and fruitfulness." For Baptism is not given to an adult, except he believe; according to Mk. 16:16: "He that believeth and is baptized, shall be saved." But it is by faith that man is incorporated in Christ, according to Eph. 3:17: "That Christ may dwell by faith in your hearts." Therefore no one is baptized except he be already incorporated in Christ. Therefore incorporation with Christ is not the effect of Baptism.
Objection 2: Further, enlightenment is caused by teaching, according to Eph. 3:8,9: "To me the least of all the saints, is given this grace . . . to enlighten all men," etc. But teaching by the catechism precedes Baptism. Therefore it is not the effect of Baptism.
Objection 3: Further, fruitfulness pertains to active generation. But a man is regenerated spiritually by Baptism. Therefore fruitfulness is not an effect of Baptism.
On the contrary, Augustine says in the book on Infant Baptism (De Pecc. Merit. et Remiss. i) that "the effect of Baptism is that the baptized are incorporated in Christ." And Dionysius (Eccl. Hier. ii) ascribes enlightenment to Baptism. And on Ps. 22:2, "He hath brought me up on the water of refreshment," a gloss says that "the sinner's soul, sterilized by drought, is made fruitful by Baptism."
I answer that, By Baptism man is born again unto the spiritual life, which is proper to the faithful of Christ, as the Apostle says (Gal. 2:20): "And that I live now in the flesh; I live in the faith of the Son of God." Now life is only in those members that are united to the head, from which they derive sense and movement. And therefore it follows of necessity that by Baptism man is incorporated in Christ, as one of His members. Again, just as the members derive sense and movement from the material head, so from their spiritual Head, i.e. Christ, do His members derive spiritual sense consisting in the knowledge Of truth, and spiritual movement which results from the instinct of grace. Hence it is written (Jn. 1:14, 16): "We have seen Him . . . full of grace and truth; and of His fulness we all have received." And it follows from this that the baptized are enlightened by Christ as to the knowledge of truth, and made fruitful by Him with the fruitfulness of good works by the infusion of grace.
Reply to Objection 1: Adults who already believe in Christ are incorporated in Him mentally. But afterwards, when they are baptized, they are incorporated in Him, corporally, as it were, i.e. by the visible sacrament; without the desire of which they could not have been incorporated in Him even mentally.
Reply to Objection 2: The teacher enlightens outwardly and ministerially by catechizing: but God enlightens the baptized inwardly, by preparing their hearts for the reception of the doctrines of truth, according to Jn. 6:45: "It is written in the prophets . . . They shall all be taught of God."
Reply to Objection 3: The fruitfulness which i ascribed as an effect of Baptism is that by which man brings forth good works; not that by which he begets others in Christ, as the Apostle says (1 Cor. 4:15): "In Christ Jesus by the Gospel I have begotten you."
