A Comparison of Neoplatonic and Christian Theology: Henosis vs. Theosis
------------------------------------------
Henosis, (ἕνωσις)
-A word meaning "unity" or "oneness"
-A transformation or elevation of the soul back to its prime source, the One (Τὸ Ἕν)
-Achieved through means of spiritual contemplation combined with theurgic rituals
-Requires an emptying and purifying of the self to achieve (katharsis)
-A full, unfiltered unity with the essence of the One, not just with its energies
Theosis, (θέωσις)
-A word meaning "deification" or "divinization"
-A restoration of human nature to a "pre-fall" state-- a sinless, semi-divine state.
-Achieved through a combination of spiritual purification (katharsis) and engaging with the energies of God through the sacraments.
-Not a "full" union with the essence of God, merely his energies.
-------------------------------------------
In Neoplatonism, henosis is more of an ascent, or a return of the soul to its original source, a full realization of our inner divinity. Theosis, in Christian belief, is a restoration of the human person, (body and soul) to a state of divine sinlessness, as it existed in the Garden of Eden. It is not a direct unity with God's essence but rather his energies, as his essence is ultimately unknowable to us. It is, in a sense, limited.
The similarities between henosis and theosis make for interesting theological discussions about human nature and the soul. Several Christian writers were influenced by Neoplatonist ideas in late antiquity, and many Christian beliefs borrow heavily from Platonism in general.
