Canon 8 Hebrews feigning Christianity are not to be received

Since some from the religion of the Hebrews, being in error, have thought fit to mock Christ our God, pretending to be Christians but denying him in secret, and secretly keeping the Sabbath, and doing other Jewish things, we decree that these be received neither into communion, nor into prayer, nor into the church, but that they be openly Hebrews according to their own religion, and that they neither baptise their children nor buy or acquire a slave. But if any of them is converted out of sincere faith, and confesses with his whole heart, making a public show of their customs and practices, so that others too may be reproved and corrected, this one is to be received and baptised, and his children too, and it is to be made sure that they depart from the Hebrew practices; but if they are not so disposed, they are by no means to be received.
