“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)
10:18 Consider Israel after the flesh - Christians are the spiritual Israel of God. Are not they who eat of the sacrifices partakers of the altar - Is not this an act of communion with that God to whom they are offered? And is not the case the same with those who eat of the sacrifices which have been offered to idols?
10:19 What say I then - Do I in saying this allow that an idol is anything divine? I aver, on the contrary, that what the heathens sacrifice, they sacrifice to devils. Such in reality are the gods of the heathens; and with such only can you hold communion in those sacrifices.
10:21 Ye cannot drink the cup of the Lord, and the cup of devils - You cannot have communion with both.
10:22 Do we provoke the Lord to jealousy - By thus caressing his rivals? Are we stronger than he - Are we able to resist, or to bear his wrath?
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.
