8:1 With regard to food sacrificed to idols, we know that “we all have knowledge.” 1 Knowledge puffs up, but love builds up. 8:2 If someone thinks he knows something, he does not yet know to the degree that he needs to know.
1 sn “We all have knowledge.” Here and in v. 4 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.
