Irenaeus on God and epektasis

And in this respect God differs from man, that God indeed makes, but man is made; and truly, He who makes is always the same; but that which is made must receive both beginning, and middle, and addition, and increase…. God also is truly perfect in all things, Himself equal and similar to Himself, as He is all light, and all mind, and all substance, and the fount of all good; but man receives advancement and increase towards God. For as God is always the same, so also man, when found in God, shall always go on towards God. (Against Heresies 4.11.2)
