Romans 14:23
King James Version
“And he that doubteth is damned if he eat, because not of faith: for whatsoever not of faith is sin.”
Context
20For meat destroy not the work of God. All things indeed pure; but evil for that man who eateth with offence.
21good neither to eat flesh, nor to drink wine, nor whereby thy brother stumbleth, or is offended, or is made weak.
22Hast thou faith? have to thyself before God. Happy he that condemneth not himself in that thing which he alloweth.
23And he that doubteth is damned if he eat, because not of faith: for whatsoever not of faith is sin.
