And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
All Commentaries on 1 Corinthians 15:28 Go To 1 Corinthians 15
Gregory the Theologian
AD 390
“God will be all in all” at the time of restoration—“God,” not “the Father.” The Son will not revert to disappear completely in the Father, like a torch temporarily withdrawn from a great flame and then joined up again with it—Sabellians must not wrest this text. No, God will be “all in all” when we are no longer what we are now, a multiplicity of impulses and emotions, with little or nothing of God in us, but are fully like God, with room for God and God alone. This is the “maturity” toward which we speed.
