Romanos 14

12 So then each of us shall give an account concerning himself to God.

13 Let us no longer therefore judge one another; but judge ye this rather, not to put a stumbling-block or a fall-trap before his brother.

14 I know, and am persuaded in the Lord Jesus, that nothing is unclean of itself; except to him who reckons anything to be unclean, to that man {it is} unclean.
