I Corinthians 10:18-22

Observe Israel after the flesh: Are not those who eat of the sacrifices partakers of the altar? What am I saying then? That an idol is anything, or what is offered to idols is anything? Rather, that the things which the Gentiles sacrifice they sacrifice to demons and not to God, and I do not want you to have fellowship with demons. You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the Lord’s table and of the table of demons. Or do we provoke the Lord to jealousy? Are we stronger than He?
