Romans 15:6

ὁμοθυμαδὸν. Acts (10) and here only: with one heart and mouth,—the expression of τὸ αὐτὸ φρονεῖν.

δοξάζητε τ. θ. “A phrase much used in both O.T. and N.T. for all forms of human recognition of GOD’s true character and work, rendered by word or by act,” Hort, 1 Peter 2:12. The special subject of recognition is here indicated by the full description.

τὸν θεὸν κ. π. τ. κ. ἡ. Ἰ. Χρ. Cf. Philippians 2:11 with context from Romans 15:2. This full description is a compendium of the Gospel, especially as the Gospel of reconciliation; and comes suitably here as the climax of the detailed exhortations to unity, echoing the appeal of Romans 12:1 to ‘the compassions of GOD.’ The whole economy of creation and redemption comes from GOD, revealed as the GOD and Father of our Lord Jesus Christ, and as in Him ‘reconciling the world to Himself.’ The full phrase occurs only in benedictions (Ephesians 1:3; 2 Corinthians 1:3; 1 Peter 1:3; cf. Colossians 1:3) or other places of special solemnity (here and 2 Corinthians 11:31 nearly). Both θεὸν and πατέρα are to be taken with τ. κ.; cf. Hort on 1 Peter 1:3 (p. 29).
