Romans 14:19-23

Young's Literal Translation

¹⁹ So, then, the things of peace may we pursue, and the things of building up one another;

²⁰ for the sake of victuals cast not down the work of God; all things, indeed, [are] pure, but evil [is] to the man who is eating through stumbling.

²¹ Right [it is] not to eat flesh, nor to drink wine, nor to [do anything] in which thy brother doth stumble, or is made to fall, or is weak.

²² Thou hast faith! to thyself have [it] before God; happy is he who is not judging himself in what he doth approve,

²³ and he who is making a difference, if he may eat, hath been condemned, because [it is] not of faith; and all that [is] not of faith is sin.
