On the Merits and Forgiveness of Sins, and on the Baptism of Infants

Nor do they fail to see this point, that his own sins are no detriment to the parent after his conversion; they therefore raise the question: “How much more impossible is it that they should be a hinderance to his son?” But they who thus think do not attend to this consideration, that as his own sins are not injurious to the father for the very reason that he is born again of the Spirit, so in the case of his son, unless he be in the same manner born again, the sins which he derived from his father will prove injurious to him. Because even renewed parents beget children, not out of the first-fruits of their renewed condition, but carnally out of the remains of the old nature; and the children who are thus the offspring of their parents’ remaining old nature, and are born in sinful flesh, escape from the condemnation which is due to the old man by the sacrament of spiritual regeneration and renewal. Now this is a consideration which, on account of the controversies that have arisen, and may still arise, on this subject, we ought to keep in our view and memory,—that a full and perfect remission of sins takes place only in baptism, that the character of the actual man does not at once undergo a total change, but that the first-fruits of the Spirit in such as walk worthily change the old carnal nature into one of like character by a process of renewal, which increases day by day, until the entire old nature is so renovated that the very weakness of the natural body attains to the strength and incorruptibility of the spiritual body.
