While I was reading Michael Horton's treatment on the history of Justification, I came across Origen's doctrine. Horton writes of Origen's Commentary on the Epistle to the Romans, "When Origen affirms justification by grace (even by the gift of Christ's merits), it is always with respect to sins before conversion". (Michael Horton, Justification, Volume 1, in New Studies in Dogmatics, p. 57) Horton notes that this thought was assumed by Lombard, when he argues, citing Jerome, that penence is a "second plank after shipwreck", and that baptism suffices only for past sins, not for future ones. (ibid., p. 98) In contrast with Origen, Chrysostom is presented as one who believed that baptism suffices for the whole life, for past sins, and also for future sins. For this argument Horton uses a citation from Homily 11 on the Epistle to the Romans: I looked at the context, and some statements not quoted by Horton seem to throw Chrysostom's argument into ambiguity. For example, from the same Homily 11: Even Augustine, when dealing with post-baptismal sins, tends to say that those sins are forgiven through prayer, almsgiving, penitence etc.. He says in the 46th chapter of his Enchiridion: This idea, that post-baptismal sins need some other sacrament for forgivness, was rejected by the Magisterial Reformers. Is there any Church Father that affirmed the sufficiency of baptism?
