1 Cor 10:14-22 is talking about avoiding idolatry, which is always a good idea, but in the middle of it, instead of saying idols are not real or figments of the pagans’ imagination Paul says they are demons. (1 Cor 10:2 Is this an important distinction – imaginary beings vs. real demons? Why or why not?
1 Cor 10:14 Therefore, my beloved, flee from idolatry. 15 I speak as to wise people; you then, judge what I say. 16 Is the cup of blessing which we bless not a sharing in the blood of Christ? Is the bread which we break not a sharing in the body of Christ? 17 Since there is one loaf, we who are many are one body; for we all partake of the one loaf. 18 Look at the people of Israel; are those who eat the sacrifices not partners in the altar? 19 What do I mean then? That food sacrificed to idols is anything, or that an idol is anything? 20 No, but I say that things which the Gentiles sacrifice, they sacrifice to demons and not to God; and I do not want you to become partners with demons. 21 You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the table of the Lord and the table of demons. 22 Or do we provoke the Lord to jealousy? We are not stronger than He, are we?
