Romans 15:6

When one common aspiration reigns in the church, secondary diversities no longer separate hearts; and from the internal communion there results common adoration like pure harmony from a concert of well-tuned instruments. All hearts being melted in one, all mouths become only one. And how so? Because one being only appears henceforth to all as worthy of being glorified.

It seems obvious to us, since the two words God and Father are joined in Greek by one and the same article, that the complement: of our Lord Jesus Christ, must depend on both. Comp. Ephesians 1:17 (“the God of Jesus Christ”); Matthew 27:46 (“my God, my God”); John 20:17 (“my Father and your Father, my God and your God”). The expression: God of Jesus Christ, denotes the relation of complete dependence; and the expression: Father of Jesus Christ, the relation of perfect intimacy. The ideal here described by the apostle, and which is the supreme object of the prayer which he has just formed, Romans 15:5, is therefore that of the union of the entire church, composed of Jews and Gentiles, in the adoration of the God and Father who has redeemed and sanctified it by Jesus Christ. This union was in a sense his personal work, and the prize of his apostolic labors. How his heart must have leaped, hearing already by the anticipation of faith, the hymn of saved humanity! It is the part of every believer, therefore, to make all the advances and all the sacrifices which love demands in order to work for so magnificent a result. So there is added, as the conclusion of all that precedes (from Romans 14:1), Romans 15:7.
