Kant closed off “the possibility of correspondence with a reality that transcends our grasp of it.” (see discussion here) We don't exactly agree, because Godhood is beyond our grasp and God perceives truths beyond our grasp yet grasps truths that are within his/her grasp.
What we would say is that we close off the possibility of truth if we try to go beyond the living object who grasps it. The denotation or definition of God does not exist as an object in itself but exists in the mind of God, which exists in the body of Godhood.
