"All terms are potentially controversial, and those who seek controversy will find it. Yet those who seek clarification will find it as well. They must, however, be willing to overlook controversy, recognizing that it is a defense against truth in the form of a delaying maneuver. Theological considerations as such are necessarily controversial, since they depend on belief and can therefore be accepted or rejected. A universal theology is impossible, but a universal experience is not only possible but necessary. Here alone consistency becomes possible because here alone uncertainty ends."
