“But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.”
King James Version (KJV)
1Co 10:20 The things which the Gentiles sacrifice, they sacrifice to devils. The idol is nothing, but to the worshiper it is a reality. That reality is not God, but really a demon. The gods were mainly dead kings and heroes who had been defiled. The "diamonia", or demons, were the spirits of dead men. The worship was really demon worship. Fellowship with devils. If the feast of the Lord's Supper is communion with Christ, the feast of the altar sacrifice communion with God, who is worshiped, the feast of the idol is communion with the idol. Yet this idol in the mind of the worshiper is a diamonion, a demon.
