Now accept the one who is weak in faith, but not for the purpose of passing judgment on his opinions. One man has faith that he may eat all things, but he who is weak eats vegetables only. Let not him who eats regard with contempt him who does not eat, and let not him who does not eat judge him who eats, for God has accepted him. Who are you to judge the servant of another? To his own master he stands or falls; and stand he will, for the Lord is able to make him stand.

Romans 14:1-4
