Canon 32

1Command 32: Concerning those who associate with heretics. If a bishop, priest, or deacon associates with heretics and invites them to eat and drink, he shall be excommunicated. If he does not, he shall be expelled. If a subdeacon, reader, or singer does this, they shall be excommunicated. If they do not, they shall be expelled. The same applies to laypeople. If a bishop, priest, or deacon commands and invites them, he shall be anathematized. If he does not, he shall be deposed.
