Thanks for the links, Randy.
“Uncreated Energies” = grace
We Orthodox are aghast at the concept of grace being something that God created. God, not a created something, is our Savior.
The 9th Ecumenical Council (held intermittently in Constantinople in 1341-1351) hammered-out the terminological precision explaining the Uncreated Energies. St. Gregory Palamas of Thessaloniki was the great saint of that council.
Through participation in God’s Uncreated Energies, we become by grace what God is by nature. We become (in the words of St. Peter) “partakers of the Divine Nature”. The distinction between the Holy Trinity (as the necessary Creator) and deified men (as contingent creations) is forever maintained.
The light of Christ at His Transfiguration was the Uncreated Energies, which are also depicted in saints’ halos in icons.
