The dialogue between psychology and religion is difficult to study for a number of reasons. First, it requires knowledge of both psychology and religion. People with a background in psychology often lack a solid understanding of the religious traditions they wish to study, and theologians may not be up to date on the latest developments in psychology. Second, it requires conceptual tools to organize the material and understand the basic problems involved in any attempt to connect the science of psychology with religion. These concepts can be found in many places, for instance in the writings of philosophers of science, but they are complex and often hard to follow for those without a proper theological and philosophical background. Finally, authors who write on the topic come to the study of psychology and religion from a variety of academic and personal backgrounds. This makes for wonderful diversity in conversations, but it makes understanding and mastery of the material quite difficult.
