Thus God became Man, as in first principles so also in ultimates. . . God from the beginning was Man in first principles, though not in ultimates; yet after He took on the Human in the world, He also became Man in ultimates. This follows from the things proved above,–that the Lord united his Human to his Divine, and thus made his Human also Divine. It is from this that He is called “the Beginning and the End, the First and the Last, the Alpha and the Omega:” as in the Apocalypse: “I am the Alpha and the Omega, the Beginning and the End, said the Lord: He who is, and who was, and who is to come; the Almighty” (Apocalypse 1:8, 11,13, 17; 2:8; 21:6; 22:12-13).
And in Isaiah: “Thus saith Jehovah, the King of Israel, and his Redeemer, Jehovah Zebaoth: I am the First and the Last” (Isaiah 44:6; 48: 12).
