Romans 14:2-6

21One person has faith that he may eat all things, but the one who is 2weak eats only vegetables. 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 10values one day over another, another 11values every day the same. Each person must be 12fully convinced in his own mind. 6The one who observes the day, observes it for the Lord, and the one who eats, 13does so with regard to the Lord, for he 14gives thanks to God; and the one who does not eat, it is for the Lord that he does not eat, and he gives thanks to God.
