I'm new to the list, but I would suggest starting the Roman approach to salvation as opposed to the Orthodox approach. I think St. Antony Khrapovitsky stated it well. The West, in general, sees God the Father being offended by Adam's/Eve's disobedience. He is an angry judge demanding justice by blood sacrifice. Jesus, offers Himself, His crucifixion satisfies the Father's demand for blood and man is saved. Could this be why the West emphasizes the Crucifixion over the Resurrection?
It appears that man's justification is merely a pronouncement and sanctification(?) begins only at the time of death. And because the West believes in created grace, is man able to be a "partaker of the divine nature"?
The Eastern view sees God as the lover of man(philanthropos) Who sent His Son, Who offered Himself to become incarnate and 'deify' man bringing him back into communion with the Holy Trinity. When man makes the decision to follow the Lord, deification, participating in the uncreated energies of God(God's grace),begins here in this lifetime and is completed after man's repose. It is not simply a pronouncement but actual participation in the "divine nature."
Can we say like St. Athanasios, "God became man, so man may become god"?
