Roma 14:14

14:14 I know and am convinced in the Lord Jesus that there is nothing unclean in itself; still, it is unclean to the one who considers it unclean.

Roma 14:22

14:22 The faith ¹  you have, keep to yourself before God. Blessed is the one who does not judge himself by what he approves.

[14:22]  ¹ tc ‡ Several important Alexandrian witnesses (א A B C 048) have the relative pronoun ἥν ({hn, “the faith that you have”) at this juncture, but D F G Ψ 1739 1881 Ï lat co lack it. Without the pronoun, the clause is more ambiguous (either “Keep the faith [that] you have between yourself and God” or “Do you have faith? Keep it between yourself and God”). The pronoun thus looks to be a motivated reading, created to clarify the meaning of the text. Even though it is found in the better witnesses, in this instance internal evidence should be given preference. NA²⁷ places the word in brackets, indicating some doubt as to its authenticity.
