The purpose of this treatise is: 1) to draw attention to the presence of situations arising within medical practice in which religious beliefs play an important role. 2) to emphasize the fact that most students and many doctors are given insufficient training in such matters, which are of considerable import to a fair percentage of the public. 3) to provide a few examples of what is meant by a religio-medical situation, and a bibliography for further exploration by the initiate in such matters.
