Romans 14:1-9

But him that is weak in faith receive ye, yet not for decision of scruples. One man hath faith to eat all things: but he that is weak eateth herbs. Let not him that eateth set at nought him that eateth not; and let not him that eateth not judge him that eateth: for God hath received him. Who art thou that judgest the servant of another? to his own lord he standeth or falleth. Yea, he shall be made to stand; for the Lord hath power to make him stand. One man esteemeth one day above another: another esteemeth every day alike. Let each man be fully assured in his own mind. He that regardeth the day, regardeth it unto the Lord: and he that eateth, eateth unto the Lord, for he giveth God thanks; and he that eateth not, unto the Lord he eateth not, and giveth God thanks. For none of us liveth to himself, and none dieth to himself. For whether we live, we live unto the Lord; or whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord’s. For to this end Christ died and lived again, that he might be Lord of both the dead and the living.
