1 Corinthians 10:19

“What say I then? etc.] Or may be objected to, or inferred from, what I say; that an idol is anything, or that which is sacrificed to idols is anything? to which must be answered, as the Syriac version reads, al, “no”, by no means; by running the parallel between Christians having communion with the body and blood of Christ, in the Lord’s supper, through eating the bread and drinking the wine, the Israelites partaking of the altar, by eating of the sacrifices of it, and men’s joining with idols and idolaters, by eating things sacrificed to idols; it follows not that an idol has anything of deity in it, and is to be set upon a level with God, when, as he had said before, an idol was nothing,…”

“What say I then?--The inference might be drawn from the analogies of the Lord's Supper and Jewish sacrifices, that an idol is really what the heathen thought it to be, a god, and that in eating idol-meats they had fellowship with the god. This verse guards against such an inference: "What would I say then? that a thing sacrificed to an idol is any real thing (in the sense that the heathen regard it), or that an idol is any real thing?" (The oldest manuscripts read the words in this order. Supply "Nay") "But [I say] that the things which the Gentiles sacrifice, they sacrifice to devils (demons)." Paul here introduces a new fact. It is true that, as I said, an idol has no reality in the sense…”

“What say I then? - This is in the present tense; τί οὖν φημι ti oun phēmi, what do I say? What is my meaning? What follows from this? Do I mean to say that an idol is anything; that it has a real existence? Does my reasoning lead to that conclusion; and am I to be understood as affirming that an idol is of itself of any consequence? It must be recollected that the Corinthian Christians are introduced by Paul 1 Corinthians 8:4 as saying that they knew that an idol was nothing in the world. Paul did not directly contradict that; but his reasoning had led him to the necessity of calling the propriety of their attending on the feasts of idols in question; and he introduces the matter now by…”

“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. 1 Corinthians 10:21”

“10:19-20 Idols have no reality or life (see 8:4-6), and sacrifices made to them accomplish nothing. The sacrifices pagans make to idols are actually unknowingly made to demons (see Deut 32:16-17; Ps 106:37; Rev 9:20). Those who share in their religious meals are thereby uniting themselves with demons.”
