Thomas Aquinas

“ Hence it is clear that by Baptism man dies unto the oldness of sin, and begins to live unto the newness of grace. But every sin belongs to the primitive oldness. Consequently every sin is taken away by Baptism. ”

“ Faith and charity depend on man's will, yet so that the habits of these and other virtues require the power of the will which is in children; whereas acts of virtue require an act of the will, which is not in children. In this sense Augustine says in the book on Infant Baptism (Ep. xcviii) : "The little child is made a believer, not as yet by that faith which depends on the will of the believer, but by the sacrament of faith itself," which causes the habit of faith. ”

“ 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. ”

“ Further, Baptism takes away the guilt of both original and actual sin. Now it takes away the guilt of actual sin in such a way as to free man from all debt of punishment resulting therefrom. Therefore it also frees man from the penalties of the present life, which are a punishment of original sin. ”

“ And so, seeing children to be incapable of acts of virtue, they thought that they had no virtues at all after Baptism. But this inability of children to act is not due to the absence of habits, but to an impediment on the part of the body: thus also when a man is asleep, though he may have the habits of virtue, yet is he hindered from virtuous acts through being asleep. ”

“ A man is said to be insincere who makes a show of willing what he wills not. Now whoever approaches Baptism, by that very fact makes a show of having right faith in Christ, of veneration for this sacrament, and of wishing to conform to the Church, and to renounce sin. Consequently, to whatever sin a man wishes to cleave, if he approach Baptism, he approaches insincerely, which is the same as to approach without devotion. But this must be understood of mortal sin, which is in opposition to grace: but not of venial sin. ”

“ Consequently no movement of the human will suffices for the remission of sin, unless there be faith in Christ's Passion, and the purpose of participating in it, either by receiving Baptism, or by submitting to the keys of the Church. Therefore when an adult approaches Baptism, he does indeed receive the forgiveness of all his sins through his purpose of being baptized, but more perfectly through the actual reception of Baptism. ”

“ The least baptismal grace suffices to blot out all sins. Wherefore that in some more sins are loosed than in others is not due to the greater efficacy of Baptism, but to the condition of the recipient: for in each one it looses whatever it finds. ”

“ For a dead work, which is void of charity, can never come to life. But he who approaches Baptism insincerely, receives the sacrament without charity. Therefore it can never come to life so as to bestow grace.
Objection 2: Further, insincerity seems to be stronger than Baptism, because it hinders its effect. But the stronger is not removed by the weaker. Therefore the sin of insincerity cannot be taken away by Baptism which has been hindered by insincerity. And thus Baptism will not receive its full effect, which is the remission of all sins. ”

“ 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. ”

“ In sign of which it is written (Judges 3:1,2) : "These are the nations which the Lord left, that by them He might instruct Israel . . . that afterwards their children might learn to fight with their enemies, and to be trained up to war." ”

“ And therefore some receive a greater, some a smaller share of the grace of newness; just as from the same fire, he receives more heat who approaches nearest to it, although the fire, as far as it is concerned, sends forth its heat equally to all. ”
