As holy reason at work, Christian theology can never escape from the sober realization that we talk in the terrifying presence of the God from whom we cannot flee (Ps. 139.7). In Christian theology, the matter of our discourse is not someone absent, someone whom we have managed to exclude from our own intellectual self-presence and about whom we can talk away safely and undisturbed. We speak in God’s presence. When we begin to talk theologically about the holiness of God, we soon enough discover that the tables have been reversed; it is no longer we who summon God before our minds to make him a matter for clever discourse, but the opposite: the holy God shows himself and summons us before him to give account of our thinking. That summons — and not any constellation of cultural, intellectual or political conditions — is the determinative context of holy reason. There are other contexts, of course, other determinations and constraints in the intellectual work of theology: theology is human work in human history. But those determinations and constraints are all subordinate to, and relativized by, the governing claim of the holy God, a claim which is of all things most fearful but also of all things most full of promise.
