The Apostle Paul
1 Thessalonians 5:26ESV·traditional attribution

Greet all the brothers with a holy kiss.

John Calvin Reformed @genevareformer

26 Salute all the brethren with an holy kiss. As to the kiss, it was a customary token of salutation, as has been stated elsewhere. See Calvin on the Corinthians, vol. 2, p. 78. In these words, however, he declares his affection towards all the saints.

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.
