But how does the energy observed in God avoid composition? Because he alone possesses an energy completely void of passion, for by it he is active only but is not also acted upon, neither coming into being nor changing.
[Gregory Palamas, The One Hundred and Fifty Chapters, Robert E. Sinewicz, tr. PIMS (Toronto: 1988) ch. 128 (p. 233).]
Here again we have the link between passive potential and composition.
In any case, there is an interesting discussion of my original post at Sacramentum Vitae.
