John Calvin on Romans 15:3

3. For even Christ pleased not himself, etc. Since it is not right that a servant should refuse what his lord has himself undertaken, it would be very strange in us to wish an exemption from the duty of bearing the infirmities of others, to which Christ, in whom we glory as our Lord and King, submitted himself; for he having no regard for himself, gave up himself wholly to this service. For in him was really verified what the Prophet declares in Psalm 69:9,10: and among other things he mentions this, that “zeal for God’s house had eaten him up,” and that “the reproaches of those who reproached God fell on him.” By these words it is intimated, that he burned with so much fervor for God’s glory that he was possessed by such a desire to promote his kingdom, that he forgot himself, and was, as it were, absorbed with this one thought, and that he so devoted himself to the Lord that he was grieved in his soul whenever he perceived his holy name exposed to the slandering of the ungodly. The intention of producing Christ’s example here is to enjoin disinterestedness. He denies himself for the sake of glorifying God in the salvation of men: so his followers ought to show the same spirit; they ought to inconvenience themselves, and undergo toil, trouble, suffering, and reproaches, if necessary, in order to help and assist their fellow-Christians. — Ed.

The second part, “the reproaches of God,” may indeed be understood in two ways, — either that he was not less affected by the contumelies which were heaped on God, than if he himself had endured them, — or, that he grieved not otherwise to see the wrong done to God, than if he himself had been the cause. But if Christ reigns in us, as he must necessarily reign in his people, this feeling is also vigorous in our hearts, so that whatever derogates from the glory of God does not otherwise grieve us than if it was done to ourselves. Away then with those whose highest wish is to gain honors from them who treat God’s name with all kinds of reproaches, tread Christ under foot, contumeliously rend, and with the sword and the flame persecute his gospel. It is not indeed safe to be so much honored by those by whom Christ is not only despised but also reproachfully treated.

Romans 15:4-6

4. For whatsoever things were written aforetime were written for our learning, that we through patience and comfort of the scriptures might have hope.

4. Quaecunque enim ante scripta sunt, in nostram doctrinam sunt scripta, ut per patientain et consolationem Scripturarum spem habeamus.

5. Now the God of patience and consolation grant you to be likeminded one toward another, according to Christ Jesus:

5. Deus autem patientiae et consolationis det vobis idem mutuo cogitare secundum Christum Iesum;

6. That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.

6. Ut uno animo, uno ore, glorificetis Deum et Patrem Domini nostri Iesu Christi.
