"For Karl Barth, theology is, human speaking, an impossibility; where it nevertheless becomes possible, it does so only as a divine possibility. A theology which has truly understood this will be one which finds its basis - not once, but again and again - in the Realdialektik of the divine veiling and unveiling. It will be a theology which takes seriously the reality of divine action not only on the level of the theological epistemology it presupposes but also on the level of the theological method it employs. On the other hand, the employment of a method which could succeed in the tasks appointed for it by its human practitioners whether God exists or not - which, in fact, would not be altered in the least by a confession of the nonexistence of God - would reduce theology to something humanly achievable, manipulable, controllable. It would reduce theology to a regular, bourgeois science alongside all other sciences."
- Bruce McCormack, Orthodox and Modern, 112.
