ing that by sin they have lost their baptism and that it profits them no more.
Guard yourself, by all means, against this error. For, as has been said, if any one has fallen into sin, he should the more remember his baptism, and how God has there made a covenant with him to forgive all his sins, if only he has the will to fight against them, even until death. Upon this truth, upon this alliance with God, a man must joyfully dare to rely, and then baptism goes again into operation and effect, his heart becomes again peaceful and glad, not in his own work or "satisfaction," but in God's mercy, promised him in baptism, and to be held fast forever. This faith a man must hold so firmly that he would cling to it even though all creatures and all sins attacked him, since he who lets himself be forced away from it makes God a liar in His covenant, the sacrament of baptism.
Baptism and PenanceXV. It is this faith that the devil most attacks. If he overthrows it, he has won the battle. For the sacrament of penance also (of which we have already spoken)[1] has its foundation in this sacrament, since sins are forgiven only to those who are baptised, i. e., to those whose sins God has promised to forgive. The sacrament of penance thus renews and points out again the sacrament of baptism, as though the priest, in the absolution, were to say, "Lo, God hath now forgiven thee thy sin, as He long since hath promised thee in baptism, and as He hath now commanded me, by the power of the keys,[2] and now thou comest again into that which thy baptism does and is. Believe, and thou hast it; doubt, and thou art lost." So we find that through sin baptism is, indeed, hindered in its work, i. e., in the forgiveness and the slaying of sin; yet only by unbelief in its operation is baptism brought to naught.- ↑ Luther here refers to his Treatise on the Sacrament of Penance, which was published just before the present treatise on baptism, in 1519. See Weimar Ed., II, pp. 709 ff. and p. 724.
- ↑ The power to forgive and to retain sin, belonging, according to Roman teaching, to the priest, and normally exercised in the sacrament of penance.
