Albert Barnes 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)

That you may with one mind. The word here used is translated "with one accord,"Acts 1:14; 2:1; 4:24.

It means unitedly, with one purpose, without contentions, strife, and discord.

And one mouth. This refers, doubtless, to their prayers and praises, so that they might join in the worship of God without contention and unkind feeling.

Divisions, strife, and contention in the church prevent union in worship. Though the body may be there, and the church professedly engaged in public worship, yet it is a divided service; and the prayers of strife and contention are not heard (Isaiah 58:4).

Glorify God. Praise or honour God. This would be done by their union, peace, and harmony, thus showing the tendency of the gospel to overcome the sources of strife and contention among people and to bring them to peace.

Even the Father, etc. This is an addition designed to produce love.

1. He is a Father; we then, his children, should regard him as pleased with the union and peace of his family.

2. He is the Father of our LORD; our common Lord; our Lord who has commanded us to be united and to love one another. By the desire of honouring such a Father, we should lay aside contentions and be united in the bonds of love.
