Romans 14:23

Again, it is to exhort him to spare the weaker, that he says this. For what good is it if he eat in doubt, and condemn himself? For I approve of him, who both eateth, and doeth it not with doubting. See how he induces him not to eating only, but to eating with a good conscience too. Then he mentions likewise the reason why he is condemned continuing in these words, "Because he eateth not of faith." Not because it is unclean, but because it is not of faith. For he did not believe that it is clean, but though unclean he touched it. But by this he shows them also what great harm they do by compelling men, and not persuading them, to touch things which had hitherto appeared unclean to them, that for this at all events they might leave rebuking. "For whatsoever is not of faith is sin." For when a person does not feel sure, nor believe that a thing is clean, how can he do else than sin? Now all these things have been spoken by Paul of the subject in hand, not of everything. And observe what care he takes not to offend any; and he had said before, "If thy brother be grieved with thy meat, now walkest thou not charitably." But if one should not grieve him, much less ought one to give him offence. And again, "For meat destroy not the work of God." For if it were a grievous act of iniquity to throw down a Church, much more so is it to do so to the spiritual Temple. Since a man is more dignified than a Church: for it was not for walls that Christ died, but for these temples.
