And here you see that Baptism, both in its power and signification, comprehends also the third Sacrament, which has been called repentance, as it is really nothing else than Baptism. For what else is repentance but an earnest attack upon the old man [that his lusts be restrained] and entering upon a new life? Therefore, if you live in repentance, you walk in Baptism, which not only signifies such a new life, but also produces, begins, and exercises it.
