[21] It is good neither to eat flesh, nor to drink wine, nor any thing whereby brother stumbleth, or is offended, or is made weak. [22] Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth. [23] And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith sin.
