Romans 14:20-23

20For the sake of meat do not destroy the work of 1God. All things indeed [are] pure; but [it is] evil to that man who eats while stumbling [in doing so]. 21[It is] right not to eat meat, nor drink wine, nor [do anything] in which thy brother stumbles, or is offended, or is weak. 22Hast thou faith? have [it] to thyself before 2God. Blessed [is] he who does not judge himself in what he allows. 23But he that doubts, if he eat, is condemned; because [it is] not of faith; but whatever [is] not of faith is sin.
