To be Sufficiently Christological, a God-World Identity narrative must account for Christ as our End AND OUR MEANS
The reflection, below, is just another way of framing my thoughts as were evoked by Tim Troutner’s Crisis of a House Divided: Jordan Wood and the End of the Ressourcement Thomist Settlement
Given just the bare bones monotheism of general revelation, the logic of analogy (even modally conceived) coupled with participation could, alone, i.e. even without the Incarnation, account for a divinizing grace that would lead to perfect happiness.
The stubborn facts of Special Revelation are, however, that God in His infinite wisdom made Christ the efficient cause of our grace; our happiness is a participation in His; and our beatific vision, therefore, depends on Him.
So, while the logics of analogy & participation, coupled with their implicit, rudimentary personalist entailments might provision not only a necessary but a sufficient framing for the gratuities of creation & grace (sans any concrete natura pura), for a robustly intersubjective protology of mutually constituted & equiprimordial persons & societies and the eminently unitive eschatological ecclesiology this all would necessarily presuppose, nevertheless, God chose to reveal His Love & share His Happiness through a particular MEANS that is radically more personal than even that constitutive universal presencing as would be implicated in mere analogy & participation, alone.
So, while it would be a caricature to suggest that the logics of analogy, participation & ontology aren't sufficiently personal (they're abundantly so!), the reality of Christ & fact of the Incarnation invite us to explore possible logics that would be more radically personal (and superabundantly so!) & sacramental.
Beyond the analogical, participatory & ontological, then, it seems that our theotic accounts certainly have a rather explicit warrant to speculate. And, to be sufficiently Christological, they'd have to employ such sublative logics as could better emphasize the relational, perichoretic & hypostatic dynamics of God's Creation & Incarnation as particularized in multiple incarnations.
