Ephesians 3:15

15.Of whom the whole family. (135) The relative , ἐξ οὗ, of whom, may apply equally to the Father and to the Son. Erasmus restricts it entirely to the Father. I do not approve of this; for readers ought to have been allowed a liberty of choice; nay, the other interpretation appears to be far more probable. The apostle alludes to that relationship which the Jews had with each other, through their father Abraham, to whom they trace their lineage. He proposes, on the contrary, to remove the distinction between Jews and Gentiles; and tells them, not only that all men have been brought into one family and one race through Christ, but that they are enabled to claim kindred even with angels.

To apply it to God the Father would not be equally defensible, being liable to this obvious exception, that God formerly passed by the Gentiles, and adopted the Jews as his peculiar people. But when we apply it to Christ, the whole of Paul’s statement agrees with the facts; for all come and blend together, as one family, and, related to one God the Father, are mutually brethren. Let us therefore understand that, through the mediation of Christ, a relationship has been constituted between Jews and Gentiles, because, by reconciling us to the Father, he has made us all one. Jews have no longer any reason to boast that they are the posterity of Abraham, or that they belong to this or that tribe, — to despise others as profane, and claim the exclusive honor of being a holy people. There is but one relationship which ought to be reckoned, both in heaven and on earth, both among angels and among men — a union to the body of Christ. Out of him all will be found scattered. He alone is the bond by which we are united.
