And thus in all things God has the pre-eminence, who alone is uncreated, the first of all things, and the primary cause of the existence of all, while all other things remain under God’s subjection. But being in subjection to God is continuance in immortality, and immortality is the glory of the uncreated One. By this arrangement, therefore, and these harmonies, and a sequence of this nature, man, a created and organized being, is rendered after the image and likeness of the uncreated God — the Father planning everything well and giving His commands, the Son carrying these into execution and performing the work of creating, and the Spirit nourishing and increasing [what is made], but man making progress day by day, and ascending towards the perfect, that is, approximating to the uncreated One. For the Uncreated is perfect, that is, God. Now it was necessary that man should in the first instance be created; and having been created, should receive growth; and having received growth, should be strengthened; and having been strengthened, should abound; and having abounded, should recover [from the disease of sin]; and having recovered, should be glorified; and being glorified, should see his Lord. For God is He who is yet to be seen, and the beholding of God is productive of immortality, but immortality renders one near unto God.
