Psalms 45:16

16Instead of thy fathers shall be thy children This also serves to show the glory and transcendent excellence of this kingdom, namely, that the children will not be inferior in dignity to their fathers, and that the nobility of the race will not be diminished after the death of Solomon; for the children which shall be born to him will equal those who had preceded them in the most excellent virtues. Then it is added, that they shall be princes in all the earth, because the empire shall enjoy such an extent of dominion on every side, that it might easily be divided into many kingdoms. It is easy to gather, that this prophecy is spoken expressly concerning Christ; for so far were the sons of Solomon from having a kingdom of such an extent, as to divide it into provinces among them, that his first successor retained only a small portion of his kingdom. There were none of his true and lawful successors who attained the same power which he had enjoyed, but being princes only over one tribe and a half of the people, they were, on this account, shut up within narrow limits, and, as we say, had their wings clipped. (173) But at the coming of Christ, who appeared at the close of the ancient Church, and the beginning of the new dispensation, it is an undoubted truth, that children were begotten by him, who were inferior in no respect to their fathers, either in number or in excellence, and whom he set as rulers over the whole world. In the estimation of the world, the ignominy of the cross obscures the glory of the Church; but when we consider how wonderfully it has increased, and how much it has been distinguished by spiritual gifts, we must confess that it is not without cause that her glory is in this passage celebrated in such sublime language. It ought, however, to be observed, that the sovereignty, of which mention is here made, consists not in the persons of men, but refers to the head. According to a frequent mode of expression in the Word of God, the dominion and power which belong properly to the head, and are applicable peculiarly to Christ alone, are in many places ascribed to his members. We know that those who occupy eminent stations in the Church, and who rule in the name of Christ, do not exercise a lordly dominion, but rather act as servants. As, however, Christ has committed to them his Gospel, which is the scepter of his kingdom, and intrusted it as it were to their keeping, they exercise, in some sort, his power. And, indeed, Christ, by his ministers, has subdued to his dominion the whole world, and has erected as many principalities under his authority as there have been churches gathered to him in divers nations by their preaching.
