Paul Tillich and Psychology: Historic and Contemporary Exploration in Theology, Psychotherapy, and Ethics, by Terry D. Cooper, Mercer University Press, 2006
book review
Wilder, Courtney (2006) Anglican Theological Review. 88(4): 626+ (questia)
The most significant point of conflict Cooper discusses in the initial comparison of Tillich's position and Fromm's is that "As a psychoanalyst and Marxist, Fromm is one of the most eloquent spokespersons for the position that humanity must heal itself and not rely on a transcendent Source to provide its redemption" (p. 63). In contrast, Cooper writes, "For Tillich, because estrangement invades all dimensions of our being, we can never offer ourselves redemption or healing" (p. 98) (ibid)
