Dialectics is the “D” word of theology. It summons the spectre of Barth. Reformed theology, though, while not historically Barthian (whatever that means) has always affirmed analogical reasoning (see Bavinck).
Analogical reasoning says a thing is and is not like another thing. This is a form of dialectics.
God is revealed in the human flesh of Jesus but in a sense he is also veiled in the flesh of Jesus. God makes present himself in Jesus but he hides his essence in Jesus.
God is indirectly identical with the creaturely medium of his revelation, the creaturely medium being Jesus’s flesh (110). If revelation is Self-revelation, then it involves the “whole” God, albeit his whole being is hidden in a creaturely veil. McCormack is clear there is no impartation of divine attributes to Jesus’s flesh.
The hiddenness of God in revelation is the hiddenness of the whole God in revelation. There is no “behind the back” of God when God reveals himself. He doesn’t hold back.
The dialectic of veiling/unveiling is not static. Veiling is ordered towards unveiling. The stand together in an “ordered history” (179).
