I Tertius, who wrote this epistle, salute you in the Lord.
I Tertius, who wrote this ('the') letter - as the apostle's amanuensis or penman,
Salute you in the Lord. So usual was it with the apostle to dictate instead of writing his letters, that he calls the attention of the Galatians to the fact that to them he wrote with his own hand (Galatians 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 affection; and the apostle, by giving his salutation a place here, would show what sort of assistants he employed.
