Romans 14:2-6

21One person has faith that he may eat all things, but he who is 2weak eats vegetables only. 3The one who eats is not to 3regard with contempt the one who does not eat, and the one who does not eat is not to 4judge the one who eats, for God has 5accepted him. 46Who are you to judge the 7servant of another? To his own 8master he stands or falls; and he will stand, for the Lord is able to make him stand.

59One person 10regards one day above another, another regards every day alike. Each person must be 11fully convinced in his own mind. 6He who observes the day, observes it for the Lord, and he who eats, 12does so for the Lord, for he 13gives thanks to God; and he who eats not, for the Lord he does not eat, and gives thanks to God.
