Nicene and Post-Nicene Fathers, Vol. IV:
Writings in Connection with the Donatist Controversy.: Chapter 20

Chapter 20.—34.  Polianus of Mileum 1658 said:  "It is right that a heretic should be baptized in the holy Church." 1659

35.  Nothing, indeed, could be expressed more shortly.  But I think this too is short:  It is right that the baptism of Christ should not be depreciated in the Church of Christ.
