History
Preserving the foundational research that shaped our understanding of psychedelic experience and mystical consciousness.
The documents collected here represent landmark moments in the scientific study of entheogenic sacraments and their relationship to genuine mystical experience. Together, they span nearly three decades of inquiry, from the original controlled experiment in 1962 to the long-term follow-up completed in 1991. The Church of Ambrosia presents these texts as primary sources for those seeking to understand the deep roots of sacramental practice.
Drugs and Mysticism: An Analysis of the Relationship between Psychedelic Drugs and the Mystical Consciousness
The original Good Friday Experiment thesis. Walter Pahnke administered psilocybin to divinity students during a Good Friday service at Boston University’s Marsh Chapel. His nine-category typology of mystical consciousness became foundational to the scientific study of religious experience.
8 chapters, appendix, and bibliography.
Pahnke’s “Good Friday Experiment”: A Long-Term Follow-Up and Methodological Critique
Twenty-five years after the original experiment, Rick Doblin located and interviewed the original subjects. His follow-up confirmed that the effects of the psilocybin experience persisted across decades, while also uncovering significant omissions in Pahnke’s original reporting.
The Church of Ambrosia publishes these documents as primary historical sources for educational and religious purposes. All texts have been digitally restored from their original publications with care taken to preserve the authors’ words faithfully.
