Albert Barnes' Bible Commentary
Romans 15 - Introduction
It may be of importance to state that between the last verse of the preceding chapter and the first verse of Romans 15, the Arabic version, some manuscripts and many of the Greek fathers, as Chrysostom, Theodoret, Theophylact, etc. have introduced Romans 16:25. Why this was done, has been a matter of controversy. The discussion, however, is of no practical importance, and most critics concur in the opinion that the present arrangement of the Greek text is genuine.
