Romans 15:5

By the double description of God as the God of patience and of consolation, He is characterized as the true source of these two graces which are communicated to us through the channel of the Scriptures. To get them we must therefore go not only to the Scriptures, but to Himself.

There is a close relation in a church between the consolation and the union of its members. When all are inwardly consoled from above, the way is paved for communion of hearts, all together aspiring vehemently after the same supreme good. It is this common impulse which is expressed by Paul's term (φρονεῖν ἐν ἀλλ). He thus returns to the principal idea of the passage, which he had left for an instant to speak of the Scriptures.

On the difference between Christ Jesus and Jesus Christ, see at Romans 1:1.
