Canon 7 How converts from the heresies are received

Those from among heretics who are being added to Orthodoxy, and to the portion of those being saved, we receive according to the order and custom set out below. Arians, and Macedonians, and Sabbatians, and Novatians, those who call themselves Cathari and Aristeri, and the Quartodecimans or Tetradites, and Apollinarians, we receive when they give written declarations 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 as we seal them we say: The seal of the gift of the Holy Spirit. But Eunomians, who are baptised with a single immersion, and Montanists, who are here called Phrygians, and Sabellians, who teach Son-Fatherhood and do certain other grievous things, and all the other heresies (since there are many here, especially those coming from the country of the Galatians): all those from among them who wish to be added to 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 thus we catechise them, and make them spend time in the church and hear the Scriptures, and then we baptise them.
