Chap. xv.—17. That therefore the baptism of John was not the same as the baptism of Christ, has, I think, been shown with sufficient clearness; and therefore no argument can be drawn from it that baptism should be repeated after heretics because it was repeated after John: since John was not a heretic, and could have a baptism, which, though granted by Christ, was yet not the very baptism of Christ, seeing that he had the love of Christ; while a heretic can have at once the baptism of Christ and the perversity of the devil, as another within the Church may have at once the baptism of Christ and the envy of the devil.
