See David Bradshaw's provocative, pleasing, and thoroughly insightful essay on the contrasting reception of Aristotle's concept of "the energy of God."
"The term ‘energy’ comes from the Greek energeia, a term coined by Aristotle. Aristotle’s earliest works use it to mean the active exercise of a capacity, such as that for sight or thought, as distinct from the mere possession of the capacity." - From The Concept of Divine Energies

"My goal in this paper is two-fold. First I wish to show that a sharply different way of thinking about God was present within the Christian tradition from an early point, that is, prior to Augustine. Second, I wish to show that this alternative conception is of live philosophical interest. Although I shall be discussing primarily Christian sources, I by no means believe that what I have to say should be of interest only to Christians. The question of what God is like, if there is a God, is of universal human importance. What ought to interest us in any answer is not what religious label it comes under, but whether it is true."
