My LORD’s BibleApostolic Constitutions, Book V 11
1You are also forbidden to swear by them, or to utter their abominable names through your mouth, and to worship them, or fear them as gods; for they are not gods, but either wicked demons or the ridiculous contrivances of men. For somewhere God says concerning the Israelites: They have forsaken me, and sworn by them that are no gods. And afterwards: I will take away the names of your idols out of their mouth. And elsewhere: They have provoked me to jealousy with them that are no gods; they have provoked me to anger with their idols. And in all the Scriptures these things are forbidden by the Lord God.
