Orthodox Theology--Spirituality of Deification
Deification means we are to become more like God through His grace or divine energies. In creation, humans were made in the image and likeness of God (Gen.1:26) according to human nature. In other words, humanity by nature is an icon or image of deity: The divine image is in all humanity. Through sin, however, this image and likeness of God was marred, and we fell.
When the Son of God assumed our humanity in the womb of the blessed Virgin Mary, the process of our being renewed in God's image and likeness was begun. Thus, those who are joined to Christ through faith in Holy Baptism begin a re-creation process, being renewed in God's image and likeness. We become, as St Peter writes, 'partakers of the divine nature" (2 Pet. 1:4).
Because of the Incarnation of the Son of God, because the fullness of God has inhabited human flesh, being joined to Christ means that it is again possible to experience deification, the fulfillment of our human destiny. That is, through union with Christ, we become by grace what God is by nature-we 'become children of God' (John 1:12). His deity interpenetrates our humanity. --->images of Dracula!
Eucharistic prayer--By the mingling of this water and wine, may we become one with his divinity just as he became one with our humanity.
