Cyprian : Since sins are not remitted save in the baptism of the Church, he who admits a heretic to communion without baptism does two things against reason: he does not cleanse the heretics, and he befouls the Christians. — The Seventh Council of Carthage Under Cyprian John Chrysostom : "And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on His name." Here it is a great thing he has uttered. For he said not, "Be baptized in His name:" but, "calling on the name of Christ." It shows that He is God: since it is not lawful to "call upon" any other, save God. Then he shows also, that he himself was not compelled: for, "I said," says he, "What must I do?" Nothing is left without witness: no; he brings forward the witness of a whole city, seeing they had beheld him led by the hand. But see the prophecy fulfilled. "To all men," it is said. For he did become a witness to Him, and a witness as it ought to be; by what he suffered, by what he did, and by what he said. — Homily on Acts 47
