1 Corinthians 8:2

8:2 If someone thinks he knows something, he does not yet know to the degree that he needs to know.

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 

1 Corinthians 8:7

8:7 But this knowledge is not shared by all. And some, by being accustomed to idols in former times, eat this food as an idol sacrifice, and their conscience, because it is weak, is defiled.

1 Corinthians 8:11

8:11 So by your knowledge the weak brother or sister, ²  for whom Christ died, is destroyed. ³

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.

² tn Grk “the one who is weak…the brother for whom Christ died,” but see note on the word “Christian” in 5:11.

³ tn This may be an indirect middle, “destroys himself.”
