Abstract
The relationship between psychology and religion has been widely debated in the field of psychology from its foundation as an empirical science to the present day. One author who was interested in the relationship between psychology and religion, the place of the latter in human nature, and its role in psychotherapy was the Viennese neurologist, psychiatrist, and philosopher Viktor Emil Frankl (1905-1997), the founder of logotherapy. This paper presents Frankl's main ideas about religion, the religious nature of the human being, and the relationship between religiosity, psychotherapy, and logotherapy, as well as a review of the main criticisms he has received in this regard. Frankl always defended the differences and limits between religion and psychotherapy, between the priestly cure of souls and the medical cure of souls, and between the salvific objective of religion and the hygienic objective of psychotherapy. In our opinion, critical authors have failed to appreciate Frankl's efforts to expose this distinction.
