Canon 95 How converts from heresy are received

Those who from among heretics join themselves to Orthodoxy and to the portion of those who are being saved, we receive according to the order and custom set down below. Arians, and Macedonians, and Novatians, who call themselves Cathari and Aristeri, and the Quartodecimans, that is, Tetradites, and Apollinarians, we receive when they give libelli and anathematise every heresy that does not think as the holy catholic and apostolic Church of God thinks, and are sealed, that is, anointed first with the holy chrism on the forehead, and the eyes, and the nostrils, and the mouth, and the ears; and, sealing them, we say: "The seal of the gift of the Holy Spirit." And concerning those who have been Paulianists and have then fled for refuge to the catholic Church, a definition has been set forth that they be rebaptised without fail. But Eunomians, who are baptised with a single immersion, and Montanists, who are here called Phrygians, and Sabellians, who hold that one and the same is both Son and Father, and who do certain other grievous things, and all the other heresies (since there are many of them here, especially those coming from the country of the Galatians), all of them who wish to join Orthodoxy we receive as pagans: and on the first day we make them Christians; and on the second, catechumens; then on the third we exorcise them, breathing three times into the face and into the ears; and so we catechise them, and make them spend time in the church and hear the Scriptures; and then we baptise them. And the Manichaeans too, and the Valentinians, and Marcionites, and those who come from similar heresies, we receive as pagans and rebaptise. But Nestorians, and Eutychians, and Severians, and those from similar heresies must make libelli, and anathematise their heresy, and Nestorius, and Eutyches, and Dioscorus, and Severus, and the other leaders of such heresies, and those who think as they do, and all the heresies mentioned above; and so partake of the holy communion.
