Romans 14:22–23
22 The faith that you have, keep between yourself and God. Blessed is the one who has no reason to pass judgment on himself for what he approves. 23 But rwhoever has doubts is condemned if he eats, because the eating is not from faith. sFor whatever does not proceed from faith is sin.1
