WHEREBY are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature.
2 Peter 1:4
PLANTING within me the longing to be made equal to the Creator, the serpent, wholly wicked, took me captive.
But through thee, All-Pure Lady, I have been recalled, most truly deified.
For thou art the Mother of God, thou gavest birth to him that deified me.

AND then is fulfilled also in him [i.e. the man of habitual virtue] the Apostolic word which says, “In him we move and are” (Acts 17:28).
HE injects himself into God alone throughout, and he imprints and fashions God alone upon himself throughout (cf. Rom 8:29).
And in this, the power of that reciprocal arrangement is demonstrated.
It is a power which divinizes the man for God through love for God, and hominizes God for man through love for mankind.
And through this noble inversion, it makes man into God, through the divinization of man, and God into man, through the hominization of God.
For the Word of God, who is God also, wishes to accomplish the mystery of his embodiment always, and in all things.
Ambigua, to John (Bishop of Cyzicus), No. 7 (MPG 91.1084A-D). My non-expert translation. I’ve taken a few liberties, including breaking the passage into several shorter sentences.
BEHOLD, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not.
Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
1 John 3:1-2
WISHING to deify man, corrupted of old, the One who out of goodness fashioned it, O Virgin, and revealed the image of the divine form, became man from thee, and proclaimed one threefold Deity.
HE who is in substance the unseen Word and Maker of all, hath appeared unto men as a man, from the pure Mother of God, calling man back to partake in Godhead.
HE loveth mankind, and so the Son of God thought it fit to be formed plainly after our fashion, from a Virgin; and he made men sharers in his divine glory.
O LIGHT, sole ruler, and Substance, threefold radiance: O thou that hast no beginning, irresistible Beauty, make thy dwelling in my heart, and reveal in me a temple, shining with light and cleansed, of thy Godhead as I cry: Bless the Lord, all ye works of the Lord!
