1. Cyprian and others, to Stephen their brother, greeting. We have thought it necessary for the arranging of certain matters, dearest brother, and for their investigation by the examination of a common council, to gather together and to hold a council, at which many priests were assembled at once; at which, moreover, many things were brought forward and transacted. But the subject in regard to which we had chiefly to write to you, and to confer with your gravity and wisdom, is one that more especially pertains both to the priestly authority and to the unity, as well as the dignity, of the Catholic Church, arising as these do from the ordination of the divine appointment; to wit, that those who have been dipped abroad outside the Church, and have been stained among heretics and schismatics with the taint of profane water, when they come to us and to the Church which is one, ought to be baptized, for the reason that it is a small matter to “lay hands on them that they may receive the Holy Ghost,” unless they receive also the baptism of the Church. For then finally can they be fully sanctified, and be the sons of God, if they be born of each sacrament; since it is written, “Except a man be born again of water, and of the Spirit, he cannot enter into the kingdom of God.” For we find also, in the Acts of the Apostles, that this is maintained by the apostles, and kept in the truth of the saving faith, so that when, in the house of Cornelius the centurion, the Holy Ghost had descended upon the Gentiles who were there, fervent in the warmth of their faith, and believing in the Lord with their whole heart; and when, filled with the Spirit, they blessed God in divers tongues, still none the less the blessed Apostle Peter, mindful of the divine precept and the Gospel, commanded that those same men should be baptized who had already been filled with the Holy Spirit, that nothing might seem to be neglected to the observance by the apostolic instruction in all things of the law of the divine precept and Gospel. But that that is not baptism which the heretics use; and that none of those who oppose Christ can profit by the grace of Christ; has lately been set forth with care in the letter which was written on that subject to Quintus, our colleague, established in Mauritania; as also in a letter which our colleagues previously wrote to our fellow-bishops presiding in Numidia, of both which letters I have subjoined copies.
