The Epistles of Cyprian

¹⁶ But what is the greatness of his error, and what the depth of his blindness, who says that remission of sins can be granted in the synagogues of heretics, and does not abide on the foundation of the one Church which was once based by Christ upon the rock, may be perceived from this, that Christ said to Peter alone, “Whatsoever you shall bind on earth shall be bound in heaven, and whatsoever you shall loose on earth shall be loosed in heaven.” And again, in the Gospel, when Christ breathed on the apostles alone, saying, “Receive the Holy Ghost: whose soever sins you remit they are remitted unto them, and whose soever sins you retain they are retained.” Therefore the power of remitting sins was given to the apostles, and to the churches which they, sent by Christ, established, and to the bishops who succeeded to them by vicarious ordination. But the enemies of the one Catholic Church in which we are, and the adversaries of us who have succeeded the apostles, asserting for themselves, in opposition to us, unlawful priesthoods, and setting up profane altars, what else are they than Korah, Dathan, and Abiram, profane with a like wickedness, and about to suffer the same punishments which they did, as well as those who agree with them, just as their partners and abettors perished with a like death to theirs?
