Romans 14:19-23

So then let us follow after things which make for peace, and things whereby we may edify one another. Overthrow not for meat’s sake the work of God. All things indeed are clean; howbeit it is evil for that man who eateth with offence. It is good not to eat flesh, nor to drink wine, nor to do anything whereby thy brother stumbleth. The faith which thou hast, have thou to thyself before God. Happy is he that judgeth not himself in that which he approveth. But he that doubteth is condemned if he eat, because he eateth not of faith; and whatsoever is not of faith is sin.
