The danger with the traditional arguments for God is that they impart the epistemological skepticism upon which they rely as normative. The reason that attains God in the ontological argument (on the basis of an incomparable difference) is deployed by Descartes, critiqued but confirmed by Kant, so that the gap between a thinker and his thought, between the noumena and phenomena, or between God and the world, is as good as it gets. (To tell the story as if it is the fault of the philosophical arguments or the philosophers, is a slight miss-telling, as it presumes philosophy or philosophers are the movers and shakers in society when they may simply be the markers of a general failure.) It is not that the arguments or their purveyors generate this dualistic epistemology, but the gap, difference, or alienation, inherent to a common understanding, articulated and explained by Kant, presumed by Hegel, followed by Heidegger, becomes the epistemological frame for generations of theologians. The dichotomy between spheres of knowledge (science/humanities, sociology/religion, theory/practice, etc.) marks modern theology, which even at its best is modern because it presumes the mind is stuck in apriori Kantian spatio-temporal categories. Biblical studies focused on the historical critical method (whether of a liberal or fundamentalist bent), or theology focused on satisfying the mind of God, going to heaven, the apophatic, or the God beyond being, all betray this dualistic epistemology. Whatever else it might have spawned (e.g. the Enlightenment, the Protestant Reformation etc.) the modern is this shared epistemological starting point presumed to be more basic than religion or particular convictions about God. It is presumed that people know in the same basic way; it is just that they have journeyed to different places along the same road. Thus, the philosophical arguments (to say nothing of Christianity so engendered) do not challenge, but utilize what everyone knows to be the case (as the arguments explicitly state it).
Natural theology as the theological prolegomena (the philosophical arguments about God serve to introduce classical forms of theology and it was this beginning point Barth was attempting to sidestep), indicate that this problem is not external but internal to the modern theological project. Given the epistemology of the philosophical arguments, as Kant saw it, Christ is simply a prototype of what can be accomplished by reason and reason cannot get us to either the noumenal or to God. Though most theologians would not want to state it so bluntly, Jean-Luc Marion’s notion that God is unknowable is the theological conclusion to working within the Kantian framework (God is without being and beyond knowing). His is only one example of a long line of theological systems which would seal off God’s essence from the incarnation (cordoning off the economic Trinity from the immanent Trinity, or disconnecting the pre-incarnate Logos from the incarnate Christ, or suggesting, with Barth, that human language is inadequate, though it can be specially appropriated for and by revelation).
The solution (let’s not go there but start elsewhere), may seem to be no solution at all in its unwillingness to engage the starting point, but my understanding is that Christianity begins elsewhere. The fittingness of the world as a dwelling place for God is where the Bible begins (creation, God walking in the garden) and ends (heaven come to earth) and it is the point of the incarnation (Emmanuel – God with us). There is no inherent incommensurateness, no gap, no duality, no noumenal/phenomenal split, as creation, language, the world, are perfectly suited to revealing God in his essence.
As I have described it elsewhere (here), we identify who God is through incarnation because this is really who God is. The Logos is the incarnate Christ and, though we can ask other questions and raise other issues, the main point (God is with us in Christ) should not be subjected to some other mode of understanding or some other speculative questioning. We may ask after the pre-incarnate Christ, but the Bible and the early Church fathers equate the Word, of John’s prologue, with the Word of the Cross and the Word of the Gospel. It is not that the Word became incarnate and then suffered on the cross, but rather the One on the cross is the identity of the Word. The mystery of God revealed as Trinity does not unfold from a fleshless (asarkos) heavenly realm but from the Word of the Gospel (the crucified and risen Lord and not the Word of God somehow devoid of the content of the Gospel). We begin as believers with the presumption that we encounter God a se (in his essence) in Christ, and this presumption tells us what sort of world we live in and what sort of creatures we are, who bear the image of God.
As Katherine Sonderegger describes it, in her “theological compatibilism,” God’s being is not remote but is known in “our earthly words and world and signs.” In what she considers a paradigmatic case, the appearance of God to Moses, “The bush burns with divine fire; yet the bush remains unconsumed. . . This event and truth simply is the mystery of the cosmos itself. . . This is the gospel. And every reflection upon epistemology and metaphysics must be in its turn gospel, rendered in formal analysis.” God has revealed his nature and his name in an unapproachable light (Moses both sees the light and turns away), that both reveals and conceals God. To call this revelatory theophany a “paradox” would be to impose a prior framework, while what is unfolding in this event fits no frame. It is not idolatry, it is not an affirmation of absolute transcendence, and it is not some sort of paradoxical contradiction, but provides its own frame of understanding. God’s transcendence does not preclude his immanence as, on many occasions culminating in Christ, God is present, without mediation, without distance, without analogy, in creation.
God manifests himself in the world and this need not be balanced out, as Aquinas would have it, with negative concepts extrapolated from his transcendence. Aquinas reasons that humans can speak of God on the basis of the divine name (Ex. 3:14) but this negativity falls short of apprehending God in his simplicity, indicated by the name. As Matthew Wilcoxen describes it, Aquinas strips away false understandings of God’s being so that his existence is shorn of all composition. No relation to creation (inclusive of the elements of human understanding) can penetrate or approach divine simplicity – God’s essence within his self-relation. This will become such standard fare in theology that it nearly goes without saying. Aquinas will set the stage for apprehending God through both the way of negation and the positive mode of revelation, and of course, subsequent to Thomas, these will become competing modes in which philosophical negation and certainty will co-opt the faith of Christ.
Understanding Jesus as Logos (as opposed to a pre-existent Christ) and recognizing with Sonderegger, God has chosen in his transcendence to be immanent/present in human history and human language, means that the world is perfectly adequate to reveal God in his essence. Humans, in their sinfulness, may not be up to this adequacy and may prefer to cling to dualism, antagonism, and a violent epistemology, but this human failure is not a delimiting factor for God. This is the point of the incarnation (the life, death, and resurrection of Christ). God does not need protecting or defending through mediating categories which preserve his transcendence. Christ is truly human and divine. Certainly, this does not mean that we know all of God in Christ or even all of Christ in Jesus. It does mean we can really know God in his essence as revealed in Christ which, in turn, points to divine hiddenness and transcendence. However, this hiddenness is forever being revealed and this transcendence is not an impassable barrier. As Sonderegger puts it, “We are never done with this invisibility and hiddenness, never done with this exceeding light, never far from this scorching fire. It is communicated to our hearts and to our intellects; yet never identified with them.”
As she maintains, we do not need to be able to spell out how God can be poured into our world and into our understanding, it is enough to report that he has and to extrapolate from his act (in Christ) how we are to interpret and receive this mighty deed. There is no end to the theological quest, no end to the questions and applications, given this compatible epistemological starting point, which forecloses on Anselm’s incomparable difference (the end point of his cosmological argument and the starting point of his ontological argument), which bequeathed to the world, not only philosophical arguments for God, but an epistemology devoid of the essence of God.
