1 tc Most mss (א* D2 H 33vid Ï) have ἐν Χριστῷ (en Cristw) after λέγω (legw) to read “I am telling the truth in Christ,” but this is probably an assimilation to Rom 9:1. Further, the witnesses that lack this phrase are early, important, and well distributed (א2 A D* F G P Ψ 6 81 1175 1739 1881 al sy co). It is difficult to explain the shorter reading if it is not original.
