Romans 14:14

14 I am convinced, being fully persuaded in the Lord Jesus, that nothing is unclean in itself. But if anyone regards something as unclean, then for that person it is unclean.

Romans 14:23

23 But whoever has doubts is condemned if they eat, because their eating is not from faith; and everything that does not come from faith is sin.
