Ephesians 3:15

the whole family--ALFORD, MIDDLETON, and others translate, "every family": alluding to the several families in heaven and in earth supposed to exist [THEOPHYLACT, Æcumenius, in SUICER, 2.633], the apostle thus being supposed to imply that God, in His relation of Father to us His adopted children, is the great prototype of the paternal relation wherever found. But the idea that "the holy angels are bound up in spiritual families or compaternities," is nowhere else in Scripture referred to. And Act 2:36, where the article is similarly omitted, and yet the translation is, "All the house of Israel," shows that in New Testament Greek the translation is justifiable, "all the family," or "the whole family": which accords with Scripture views, that angels and men, the saints militant and those with God, are one holy family joined under the one Father in Christ, the mediator between heaven and earth (Eph 1:10; Phi 2:10). Hence angels are termed our "brethren" (Rev 19:10), and "sons of God" by creation, as we are by adoption (Job 38:7). The Church is part of the grand family, or kingdom, which comprehends, besides men, the higher spiritual world, where the archetype, to the realization of which redeemed man is now tending, is already realized. This universal idea of the "kingdom" of God as one divine community, is presented to us in the Lord's Prayer. By sin men were estranged, not only from God, but from that higher spiritual world in which the kingdom of God is already realized.
