Romans 14:1-4

Now accept the one who is weak in faith, but not to have quarrels over opinions.

One person has faith that he may eat all things, but the one who is weak eats only vegetables.

The one who eats is not to regard with contempt the one who does not eat, and the one who does not eat is not to judge the one 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 he will stand, for the Lord is able to make him stand.
