Theophylact of Ohrid, on 1Cor 12:2

“You know that when you were heathens, you went to dumb idols, according as you were led.”

“He gives a sign of a soothsayer for distinguishing a prophet, and says: whoever prophesies through idols, under the inspiration of an unclean spirit, is as if led by someone, dragged along bound by the spirit, knowing nothing of what he utters, but being in a state of frenzy and demonic possession. But a prophet is not like that; he speaks everything with a sound mind. This is the first distinction between a demon-possessed diviner and a God-inspired prophet.”
