I stopped publicly debating and communicating with Thomas Hatsis in August 2019, after receiving a slanderous and threatening email from him. I will explain below what promoted this unprofessional outburst. However, due to the February 2022 posting on Graham Hancock’s popular website of Hatsis’ recent screed against me and The Psychedelic Gospels‒ and against all scholars who “argue for the mushrooms in Christian art hypothesis”‒I felt an obligation to readers and to the field of psychedelic studies to set the record straight by writing this Reply to the Hatsis Review. In this Reply, I will also propose a framework for revitalizing the study of mushrooms in Christian art (MICA), and focus the field on the central question: to what extent are psychoactive mushrooms present in Christian history?
