Nicene and Post-Nicene Fathers: Series I/Volume IV/Donatist Controversy/On Baptism/Book VI/Chapter 16

26.&#160; Nicomedes of Segermi said:&#160; "My judgment is that heretics coming to the Church should be baptized, because they can obtain no remission of sins among sinners outside."

27.&#160; The answer to which is:&#160; The judgment of the whole Catholic Church is that heretics, being already baptized with the baptism of Christ, although in heresy, should not be rebaptized on coming to the Church.&#160; For if there is no remission of sins among sinners, neither can sinners within the Church remit sins; and yet those who have been baptized by them are not rebaptized.
