Gregory Palamas

“For who that possesses reason and beholds such manifest differences among beings-both the oppositions of hidden forces and the compensating kinetic impulses, and again stability that compensates in another way; the ceaseless resolutions arising out of contrary affections and the unconfused harmony arising out of irreconcilable strife; the cohesion of things that are distinct and the continuing distinction of those that are united, whether they be minds, souls, or bodies; the harmony among so many, their established positions and relations; the conformity of their states and ranks to their essence, the indissolubility of their connection-who that attends to all these points would not form a conception of the One who has so well established each thing in itself and wondrously harmonized each with the others, so as to come to know God from his image that which he has caused?”
― Gregory Palamas, Gregory Palamas: The Triads

“The knowledge and contemplation that comes about through creatures is called 'natural law' Thus, even before the patriarchs and prophets and the written law, it summoned the human race and returned it to God, and showed indirectly the Creator to those who did not abandon the natural knowledge of the wise among the Greeks.”
