22. I, Tertius, who wrote this--"the"
      epistle--as the apostle's amanuensis, or penman.
      salute you in the Lord--So usually did the apostle dictate his epistles, that he calls the attention of the Galatians to the fact that to them he wrote with his own hand (Ga 6:11). But this Tertius would have the Romans to know that, far from being a mere scribe, his heart went out to them in Christian affection; and the apostle, by giving his salutation a place here, would show what sort of assistants he employed.
