The center of theology, I shall argue, is philosophical theology, that is, philosophical analysis of fundamental religious concepts and claims. Whether there can be any revelation, general or special, and which putative revelation or revealed theology, if any, is genuine must be settled by reference to philosophical criteria. Whether the very concept of God itself is a coherent concept such that there could be a revelation, a legitimate object of faith, and a source of religious truth, must be made out on philosophical grounds. … The critical question is: Can philosophy justifiably be the kind of arbiter I am maintaining it can?
