Theosis (Deification)
Made not merely forgiven but transformed, partakers of the divine nature
Theosis describes salvation as the transformation of the human person, by grace, into the likeness of God, becoming what 2 Peter calls a 'partaker of the divine nature.' Rooted in Irenaeus, Athanasius, and Maximus the Confessor, it does not mean becoming God in essence. Traditions differ in emphasis: it is central and explicit in Eastern Orthodoxy, while Catholics and some Protestants affirm related ideas in qualified and differently framed ways.
