Abstract
In the present study, we are discussing the actually quite important matter for the theology of the Eastern Christianity on the real existence of the divine energies and their relation to the divine essence. Following Gregory Palamas’ treatise entitled Περί θείας ἑνώσεως και διακρίσεως we attempt to approach his theory on unions and distinctions, which proves just the two ways in which God exists. In the gnoseological level, we are discussing how affirmative, apophatic and superlative theologies are combined, in order to become clear that God is totally unknown as to his essence, but, up to a certain point, knowable as to the projections of his energies. Our main goal is to show that Gregory Palamas is absolutely consistent with the previous Christian tradition.
