1 Corinthians 8:9-10

8:9 But be careful that this liberty of yours does not become a hindrance to the weak. 8:10 For if someone weak sees you who possess knowledge dining in an idol’s temple, will not his conscience be “strengthened” ¹  to eat food offered to idols?

1 Corinthians 10:28-29

10:28 But if someone says to you, “This is from a sacrifice,” do not eat, because of the one who told you and because of conscience ²  – 10:29 I do not mean yours but the other person’s. For why is my freedom being judged by another’s conscience?

Romans 14:14

14:14 I know and am convinced in the Lord Jesus that there is nothing unclean in itself; still, it is unclean to the one who considers it unclean.

Romans 14:23

14:23 But the man who doubts is condemned if he eats, because he does not do so from faith, and whatever is not from faith is sin. ³ 

[8:10]  ¹ tn Or “built up”; This is the same word used in v. 1b. It is used ironically here: The weak person is “built up” to commit what he regards as sin.

[10:28]  ² tc The Byzantine texttype and a few other witnesses (H^c Ψ Ï) essentially duplicate v. 26 at the end of this verse (with γάρ [gar, “for”] in second instead of third position), which itself is a quotation from Ps 24:1 (23:1 LXX). Not only is there a vast number of early, important, and diverse witnesses that lack this extra material (א A B C* D F G H* P 33 81 365 630 1175 1739 1881 2464 latt co), but the quotation seems out of place at this point in the discourse for Paul is here discussing reasons not to partake of food that has been sacrificed to idols. Perhaps scribes felt that since food is from the Lord, to eat meat sacrificed to idols contradicts that belief. Either way, the better witnesses lack the clause which, had it been authentic to v. 28, would have not occasioned such a widespread excision. The evidence is thus compelling for the shorter reading.

[14:23]  ³ tc Some mss insert 16:25-27 at this point. See the tc note at 16:25 for more information.
