The Apostle Paul
Romans 16:27ESV·traditional attribution

to the only wise God be glory forevermore through Jesus Christ! Amen.

Matthew Henry Presbyterian @wholebiblehenry

Here the apostle solemnly closes his epistle with a magnificent ascription of glory to the blessed God, as one that terminated all in the praise and glory of God, and studied to return all to him, seeing all is of him and from him.

Commenting on Romans 16:25-27

Albert Barnes Presbyterian @notesbybarnes

Verse 27. To God only wise. The apostle here resumes the doxology which had been interrupted by the parenthesis. The attribute of wisdom is here brought into view, because it had been particularly displayed in this plan which was now revealed. It evinced, in an eminent degree, the wisdom of God.

Jamieson-Fausset-Brown Reformed @jfbcommentary

To God, &c.--"To the only wise God through Jesus Christ, be"--literally, "to whom be"; that is, "to Him, I say, be the glory for ever. Amen." At its outset, this is an ascription of glory to the power that could do all this; at its close it ascribes glory to the wisdom that planned and that presides over the gathering of a redeemed people out of all nations.
