What is the reality of divine–human communion?

The nature of divine–human communion was the central issue in the hesychast controversy. This raises the question of the nature of divine grace. Basing his discussion on Dionysius the Areopagite, Palamas argues that grace is both the giver and the gift, both essence and energy, for Scripture (Joel 3:1, LXX) says that God will pour out from his Spirit, making a distinction between the pourer and the poured. Palamas’ discussions of how grace is appropriated focus on the vision of light, the meaning of enhypostatic existence, and the nature of symbols. He argues that if grace is merely created, as Akindynos maintained, we could have no communion with God, because we would have nothing bridging the ontological divide between the Creator and the creature.
