Show me a discussion of Essence/Energy from the early medieval Fathers that is not in the context of the Economy.
From Cyril’s Thesaurus 18: Ἀλλὰ τὸ μὲν ποιεῖν, ἐνεργείας ἐστὶ, φύσεως δὲ τὸ γεννᾷν. Φύσις δὲ καὶ ἐνἐργεια οὐ ταθτόν· οὐκ ἄρα τῷ γεννᾷν τὸ ποιεῖν ταθτὸν ἔσται. St. Cyril of Alexandria, like his predecessor St. Athanasius recognized, that essence and energy cannot be the same.
See also what Gregory of Nyssa writes in Against Eunomius II.31-2:They insist that, because the Father’s being is simple, it must be reckoned nothing else but unbegottenness, since it is said to be unbegotten. To them we may also reply that, because the Father is also called Creator and Designer, and the one so called is also simple in being, it is time these clever people announced that the Being of the Father is ‘creation’ and ‘design’, since no doubt the argument from simplicity attaches to his being the meaning of every word which applies to him. So they should either separate unbegottenness from their definition of the divine being, letting it retain its own proper meaning, or, if, because of the simplicity of the Subject, they do define the being by unbegottenness, they should on the same grounds envisage both creation and design in the Father’s being, not as though the potency in the being were what creates and designs but as though that potency itself were seen as creation and design.
The Argument, according to Gregory of Nyssa, is that there must be some ontological distinction between the essence (the being) of God, and the names of God (which describe either the energies of God, or what God is not). Otherwise, to say that God is the Creator is to say that creation is the essence of God, and to say that God is the designer is would be to say that the essence of God is design. The names of God do not name the essence.
All the Fathers say that the Essence is simple. All the Fathers say that the Energy is simple.
When have I said otherwise?
St. Basil immediately comes to mind. He stated that there is not multiplicity or compoundness in God, which is why we say “God is Good” or “God is Holy.” We do not say that God is composed of goodness and holiness, and other attributes.
Again, when did I say in this thread that God is composed?
We do not refer to the Energies of God, but rather the Energy of God. The Energy appears as a multiplicity only from our limited human perspective, but within God Himself, there is no such distinction in attirbutes.
This is not entirely correct or in line with Cappadocian thought. The essence can have nothing predicated of it, because it is unknowable. But the energies can be named, and furthermore, those names apply to God as well, but not to His essence. St. Basil makes this clear in his epistle 234: But God, he says, is simple, and whatever attribute of Him you have reckoned as knowable is of His essence. But the absurdities involved in this sophism are innumerable. When all these high attributes have been enumerated, are they all names of one essence? And is there the same mutual force in His awfulness and His loving-kindness, His justice and His creative power, His providence and His foreknowledge, and His bestowal of rewards and punishments, His majesty and His providence? In mentioning any one of these do we declare His essence? If they say, yes, let them not ask if we know the essence of God, but let them enquire of us whether we know God to be awful, or just, or merciful. These we confess that we know. If they say that essence is something distinct, let them not put us in the wrong on the score of simplicity. For they confess themselves that there is a distinction between the essence and each one of the attributes enumerated.
Notice how he asks the rehtorical question, “And is there the same mutual force, in His awfulness and His loving-kindness, His justice and His creative power, His providence and His foreknowledge, and His bestowal of rewards and punishments, His majesty and His providence?” He answers this very rhetorical question in Against Eunomius 1.8:Gladly, then, would I scrutinize him to see if he similarly sticks to this prudence in the case of all that is said about God, or if he does so only in the case of this word. For if he does not consider anything at all by way of conceptualization so as to avoid the appearance of honoring God with human designations, then he will confess this: that all things attributed to God similarly refer to his substance [for context, Basil is arguing that Eunomius cannot privilege one attribute, unbegottenness, to refer to the essence, while not affirming the same of all of the other attributes]. But how is it not ridiculous to say that his creative power is his substance? Or that his providence is his substance? Or the same for his foreknowledge? In other words, how is it not ridiculous to regard every activity of his as his substance? And if these names converge upon a single meaning, each one has to signify the same thing as the others, such as is the case with polyonyms, as when we call the same man ‘Simon,’ ‘Peter,’ and ‘Cephas.’ In the same vein, whoever has heard that God does not change will be lead to his unbegottenness, and whoever has heard that he has no parts will also be brought to his creative power. What is more absurd than this confusion? Each of these names is deprived of its proper signification, and conventions are established that contradict both common usage and the teaching of the Spirit.
