The Apostle Paul
1 Thessalonians 5:28BSB·traditional attribution

The grace of our Lord Jesus Christ be with you.

Matthew Henry Presbyterian @wholebiblehenry

In these words, which conclude this epistle, observe, I. Paul's prayer for them, Th1 5:23. He had told them, in the beginning of this epistle, that he always made mention of them in his prayers; and, now that he is writing to them, he lifts up his heart to God in prayer for them. Take notice, 1. To whom the apostle prays, namely, The very God of peace.

Commenting on 1 Thessalonians 5:23-28

Albert Barnes Presbyterian @notesbybarnes

Verse 28. The grace of our Lord Jesus Christ, etc. . In regard to the subscription at the close of the epistle, purporting that it was written from Athens, see the Intro. paragraph 3. These subscriptions are of no authority; and the one here, like several others, is probably wrong.

Jamieson-Fausset-Brown Reformed @jfbcommentary

(See on Co2 13:14.) Paul ends as he began (Th1 1:1), with "grace." The oldest manuscripts omit "Amen," which probably was the response of the Church after the public reading of the Epistle. The subscription is a comparatively modern addition.
