Nicene and Post-Nicene Fathers, Vol. IV:
Writings in Connection with the Donatist Controversy.: Chapter 28

Chapter 28.—54.  Another Saturninus of Abitini 1835 said:  "If Antichrist can give to any one the grace of Christ, then can heretics also baptize, who are called Antichrists." 1836

55.  What if another were to say, If a murderer can give the grace of Christ, then can they also baptize that hate their brethren who are called murderers?  For certainly he would seem in a way to speak the truth, and yet they can baptize; in like manner, therefore, can the heretics as well.
