Kuntz, Paul G.  "Can Whitehead Be Made a Christian Philosopher?"  Process Studies 12, no.4 (Winter 1982): 232-42.

Abstract

This article grants the orthodox case that Whitehead was not an ecclesiastical or creedal Christian.  He was, however, a cultural Christian, and a keen critic of what had gone wrong theoretically and morally with Christianity.  Having rejected orthodoxy, he produced a philosophy consciously influenced by religious experience and available, as now used, as basis of a "Christian natural philosophy."  Among the reforms implicit is to universalize Christianity and encourage changes influenced and by all other aspects of culture and by other world religions.  [Abstract from The Philosopher's Index]
