Pardon a second post from the comments section of Classical Theism where Malcolm and I are batting ideas back and forth. I’m pretty sure no one else is in there, so I wanted to post more publicly a reference to Greg Boyd’s appropriation of the concept of dispositions or dispositional ontology and how it might provide an analogy for understanding how God’s triune identity remains unchanged through relations with the temporal world. Chase down Greg’s Redux if you’re more interested.
Malcolm: If God has a certain state of existence ad intra and also a certain state of existence ad extra, then it seems that in transitioning from the one to the other God changes in his essential properties, in which case he doesn’t maintain identity. For instance, if God ad intra is independent but then becomes dependent, it seems to me either (a) his independence ad intra is not an essential property, or (b) God ceases being God afterwards.
Tom: If you get Greg’s Redux (pp. 16-21), check out what he says about the category of dispositions, including two kinds of disposition: (1) definitional dispositions that are exercised invariantly and whose exercise constitutes the definitional or necessary properties of a thing (Note: I don’t think God is a “thing”), and (2) constitutive dispositions (‘constitutive’ is what Greg calls them but that’s probably not a good word to use), i.e., powers which a thing essentially possesses but which it may or may not exercise and remain the essential thing it is.
God’s infinite specious present is God’s essential and necessary disposition to be the triune God of infinite beauty and beatitude. This dispositional essence cannot (I don’t think) be the product or outcome of “temporal becoming” (as I try to describe in that post on the specious present). But when we move to ad extra self-expressive divine acts, these are not (as your comment seems to suppose, I’m not sure) a “transition from the one” (i.e., from the necessary-essential disposition to be triune fullness) “to the other” (i.e., to a freely exercised disposition for creative self-expression). God doesn’t shut down the exercise of his definitional disposition to be the God he is so he can rewire or re-constitute that disposition to become someone or something else. The latter disposition (for freely creative self-expression) is possessed necessarily. It’s only exercised contingently.
God’s ‘identity’ then is the abiding, unchanging, disposition to be the loving triune God of infinite beauty and beatitude (his ‘specious present’ I would say). This ‘identity’ gets “expressed” (not “constituted”) through the ad extra work of creation, but only (and this is important to our passibilism question) through the world’s ‘being’ (i.e., the extent to which created natures conform to their logoi), not through its ‘failure to be’ (i.e., its sinful misrelation and suffering).
From my view, changing states of mind in God with respect to the changing actualities of the world, even if they are intrinsic in the sense that all knowing is intrinsic to the knower, don’t constitute an intolerable divine “becoming” or reconstitute God’s identity ad intra. Why not? Because all the forms of the good which are the being of created things are already present in the divine Logos (and so definitive of the divine identity). Their ‘becoming actual’ as non-divine entities ad extra is merely expressive of this One’s disposition for free, creative self-expression. But though created things merely reflect as images the Logos in whom their possibilities are grounded (they’re not ‘new’ in that sense, obviously), their actual temporal becoming does constitute something new ‘to know’ even for God (since their contingent, temporal ‘actuality’ as such cannot be eternally pre-contained in the Logos). As Bulgakov said (Bride of the Lamb – thank you God for this passage):
If God created man in freedom, in His own image, as a son of God and a friend of God, a god according to grace, then the reality of this creation includes his freedom as creative self-determination not only in relation to the world but also in relation to God…
[A]ll the possibilities of creaturely being, having their roots in the Creator’s knowledge, are open to [his] knowledge, since they belong to the world created by Him and are included in this world’s composition, not only in the form of “integral wisdom” but also in the form of a distributed multiplicity. In this sense, creation – in both the spiritual and the human world – cannot bring anything ontologically new into this world; it cannot surprise or enrich the Creator Himself. But the very choice and creative actualization of these possibilities, that is, the domain of modal freedom, remain entrusted to creation and to this extent are its creative contribution. Although creation cannot be absolutely unexpected and new for God in the ontological sense, nevertheless in empirical (“contingent”) being, it represents a new manifestation for God Himself, who is waiting to see whether man will open or not open the doors of his heart. God Himself will know this only when it happens…
Veiling His face, God remains ignorant of the actions of human freedom. Otherwise, these actions would not have their own reality, but would only be a function of a certain divine mechanism of things.
