The Civic Project of Christianity

"First, a purely juridical order devoid of metaphysical and theological judgment is as logically and theologically impossible as a pure, metaphysically innocent science. One cannot set a limit to one’s own religious competence without an implicit judgment about what falls on the other side of that limit; one cannot draw a clear and distinct boundary between the political and the religious, or between science, metaphysics, and theology, without tacitly determining what sort of God transcends these realms. The very act by which liberalism declares its religious incompetence is thus a theological act. Its supposed indifference to metaphysics conceals a metaphysics of original indifference. A thing’s relation to God, being a creature, makes no difference to its nature or intelligibility. Those are tacked on extrinsically through the free act of the agent."
