A.T. Robertson Commentary Romans 15:6

"that with one accord ye may with one mouth glorify the God and Father of our Lord Jesus Christ." — Romans 15:6 (ASV)

With one accord (ομοθυμαδον). Here alone in Paul, but eleven times in Acts (Acts 1:14, etc.).

With one mouth (εν εν στοματ). Vivid outward expression of the unity of feeling.

May glorify (δοξαζητε). Present active subjunctive of δοξαζω, final clause with ινα "that ye may keep on glorifying." For "the God and Father of our Lord Jesus Christ" see 2 Corinthians 1:3; 9:31 for discussion. It occurs also in Eph 1:3; 1 Peter 1:3.
