Psychology of Prophecy in Early Christianity analyzes early Christian prophetic activity and seeks to understand the psychological states behind it. A system of categories is suggested based on the external appearances and subjective claims of modern phenomena. Assuming that the ancients followed the same patterns, most instances described in early Christian literature are reviewed and categorized.

Indigenous (Greek and Hebrew) categories are also discussed, and an attempt is made to determine the expectations provided by both the Jewish and Greco-Roman worlds. The material is reviewed statistically by date, sect, social context, psychological type and region.
