A theologian who does not take full advantage of the way psychology illumines theology is not serious about the work of theology. psychologist who does not take full advantage of the way theology illumines psychology is not serious about the field and practice of psychology. Science, Religion, and Health explains in readable style how that interface and mutual illumination works, and why it is crucial for Christian psychotherapists and pastors.
