what is created is not God’s energy - this is impossible - but what is effected and accomplished by the divine energy… the energy, although distinct from the divine nature, is also an essential, that is to say, a natural activity of that nature.
Palamas establishes the axiomatic distinction: divine energy is uncreated and natural to God’s essence, while creatures are only its effects, not the energy itself.
