Roma 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.

Roma 14:21

14:21 It is good not to eat meat or drink wine or to do anything that causes your brother to stumble. ¹ 

¹ tc A large number of mss, some of them quite important (Ì^46vid א² B D F G Ψ 0209 33 1881 Ï lat sa), read “or to be offended or to be made weak” after “to stumble.” The shorter reading “to stumble” is found only in Alexandrian mss (א* A C 048 81 945 1506 1739 pc bo). Although external evidence favors inclusion, internal evidence points to a scribal expansion, perhaps reminiscent of 1 Cor 8:11-13. The shorter reading is therefore preferred.
