“Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth.”
King James Version (KJV)
14:22 Hast thou faith - That all things are pure? Have it to thyself before God - In circumstances like these, keep it to thyself, and do not offend others by it. Happy is he that condemneth not himself - By an improper use of even innocent things! and happy he who is free from a doubting conscience! He that has this may allow the thing, yet condemn himself for it.
Ro 14:22 Hast thou faith? Art thou strong in the faith, and possessed of knowledge that the weaker brethren have not? Let God take not of it, but do not parade it before the weak. Happy [is] he that condemneth not himself, etc. If one "allowed" that he had the right to eat all kinds of meats, etc., and did it to the injury of his brother, he would condemn himself, because he trampled on the law of love.
