1 Corinthians 10:19

10:19 Am I saying that idols or food sacrificed to them amount to anything?

1 Corinthians 8:4

8:4 With regard then to eating food sacrificed to idols, we know that “an idol in this world is nothing,” and that “there is no God but one.” ¹ 

[8:4]  ¹ sn “An idol in this world is nothing” and “There is no God but one.” Here and in v. 1 Paul cites certain slogans the Corinthians apparently used to justify their behavior (cf. 6:12-13; 7:1; 10:23). Paul agrees with the slogans in part, but corrects them to show how the Corinthians have misused these ideas.
