My own partial transcription from portions of this excellent conversation between David Bentley and Tony Golsby-Smith about Gregory of Nyssa:
[Gregory of Nyssa] is arguably the first metaphysician who in any significant way explored the metaphysics of divine infinity. …Infinity was ascribed to God …very rarely in Platonic tradition. The invite was not taken to be a positive attribute for many schools of thought until fairly late in the development of Hellenistic philosophy. He had is own anthropology. He had is own approach to an understanding of the nature of the human being, the nature of creatures as thoroughly dynamic expressions of being in relation to a God who is infinite. I don’t think that anyone before Gregory was as successful as he at arguing that the very things that for a more standard metaphysics would be seen as separating humanity from the divine—that is the mutably, the changeableness of human nature—Gregory was able to treat as the very terms of union with God. That is he had a very specific theology of the way in which human beings are related to God in union with God that was his rather creative use of a verse from Paul [Ph. 3:13] of eternal dynamic ascent into the divine. That our union with God, our eternal union with God, would be one also of eternal novelty, of epectasis [ἐπεκτεινόμενος], of being stretched out into an ever greater embrace that, by virtue of the divine infinity, is inexhaustible and by virtue of the inexhaustibly changing nature of the creature is nonetheless something in which we can participate. …All of this, in its own way, is quite original.
All sorts of things are called gods. Saints are called gods. John of Damascus and the other church fathers often speak of saints as gods because they don’t mean God in the sense of God most high. They just mean a divinized creature.
What does it mean to say [with the Nicene Creed established by Gregory and his fellow Cappadocians] that in Christ God has entered into immediate communion with humanity? What is humanity? How is it that God, by becoming one man, in another sense is present in all of humanity, pervades the entirety of human experience that is available to all of the spirit? This leads to Gregory of Nyssa coming up with all sorts of fascinating claims about what it is to be human, what it is to be truly human, how God created humanity form the vantage of eternity as apposed to the process of creation in time and how these two relate. Here he far surpassed his brother [Basil] and Gregory of Nazianzus in the range of speculative genius and also theological profundity. The picture of the human that emerges from it is one of a sort of radical coinherence, radical community, such that the human essence itself is one that is community before it is individuated in persons.
What he does with the Life of Moses is he turns this into a mystical treatise about he ascent of the soul into God’s infinity. And the other is his great commentary on the Song of Songs which …has all these odd premonitory hints of a kind of almost romantic vision of the soul as this infinite insatiable energy that is plunged by its error for the divine, striving—not tragically striving—but nonetheless moved by this insatiable hunger for the beauty of God into ever-deeper communion.
[Gregory of Nyssa] recognizes the animality, the physicality, the degree to which, especially for fallen humanity, [it is given] in preparation for the fall. He talks about preparing certain organs (among them, organs of procreation) to be appropriate to the life that we live in this mortal flesh now. …At the same time, he realizes that even in this condition—he’s always …recogniz[ing] this divine light, this divine music even in the human[‘s] most indigent and coarsely physical form.
In a sense, [Gregory of Nyssa] starts [the creation story] at the end. The creation of humanity starts—he does this wonderful thing where he takes the two different creation accounts, Genesis 1 and Genesis 2, and makes them, so to speak, two different creative horizons within God’s working—he beings with the human being as already glorified, already united to Christ, already in its totality, all human being together rejoicing in and divinized by the presence of God. From there—that’s the primordial creative act of God, the eternal already accomplished end—from there then unfolds, even from the conditions of sin, how does God create us in time—this being not just the end of the story, but its foundation, its beginning. Rather than starting from this sort of tragedy of a promising creature created in a limited landscape of possibilities, who makes a mess of things, condemns himself and his descendants, …that’s actually an interval in the story that is surpassed before the story even gets underway.
You are confronted first and foremost with this dizzying claim that humanity created after the image fo God in the beginning was nothing less than the totality of all human beings throughout time united in a single body divinized, joined to Christ and thoroughly plunged into the life of God. That’s where the story begins.
I’m a great champion of the romantic movement—especially the English romantic—the great rebellion against the mechanization, and I have no problem with a full robust, red blooded, seemingly panentheistic [vision]. I think that this is another reason to read Gregory On the Making of Humanity and Basil in the Hexameron. …Now, there is a certain degree of the Platonic melancholy there, a certain distrust of matter. You just can’t get away from that in the fourth century, especially in a fallen world. …But they are not talking about a world in which dead matter is the fictile clay by which God creates a working order of mechanisms related to him only in terms of his power. It really is for [them] a vision of created as pervaded by the Spirit of God. It really is the πνεῦμα, the breath of God really does permeate, fill and enliven all things. Life is literally at once the eternal spirit of God but actually the breath of God in all things. It is perfectly healthy to see the romantic rebellion [as being] against the mechanized picture—either the dualistic or the materialist version—this picture of creation as nothing but a collection of organic machines and matter as something inherently dead which is brought to life simply as a mater of functional arrangement but that in itself [is dead]. For Gregory, everything is just the mirror of the divine nature. …In both Basil and Gregory, they both deny that there is even, in any meaningful, sense a material substrate. Their understanding of matter—I don’t know if you’d say that it’s Berkeleian, that’s a bit of an anachronism—but their understanding of matter or the material creation is that it exists as a coalescence of radiant forms [Greek phrase given here, 41:53], of pure spiritual forms. They don’t believe that there is any sort of inanimate, non-divine, non-illuminated, purely passive level of material existence. And this is something that [Gregory] shared with Basil.
The portion in this conversation above about the two nested horizons of God’s creative work provides some helpful language regarding the nature of the cosmos that we inhabit now (see three previous posts here, here and here for just a few other examples of material in my blog related to this). Gregory considers there to be a foundational work of creation outside of time (both the beginning and the end of this current world) in which there is a “humanity created after the image fo God in the beginning [that] was nothing less than the totality of all human beings throughout time united in a single body divinized, joined to Christ and thoroughly plunged into the life of God.” This fullness of humanity is Adam made in the perfect image of God’s eternal son. This undifferentiated humanity falls at the moment of its creation (as Maximus the confessor puts it in three places) and Jesus Christ is therefore the “Lamb slain from the foundations of the cosmos” (Revelation 13:8) and the second Adam to whom all of humanity must remain united in order for the image of God to be preserved. Within fallen time, this image of God is now being differentiated as a kind of secondary work of creation—God’s joining with us in sin and death to nonetheless participate fully with even the life of fallen creation and to accomplish the end of God’s primary creative work. Later in the conversation, David summarizes Gregory as saying that, from our current perspective, creation has not yet taken place. From God’s eternal perspective, it can be clearly inferred as well, it has already taken place.
This entire interview is well worth listening to, and I hope the entire thing is transcribed. Two more are planned focussing on other writings of Gregory. This first interview touches on many other topics such as: Who were all of the Cappadocian saints and what is the nature of the Christian orthodoxy that they were critical in helping to establish? Why did Gregory advocate for the release of all slaves when no other Christian thinker (or likely any human thinker ever) had done so before in this way? Was Gregory a widower and what did Gregory say about marriage and monastic life? How does Gregory compare to Coleridge?
