On this episode of Prove All Things, Jeff and Mike welcome guest Gary Haegerich for an in-depth examination of the increasingly popular Zadok Calendar. Together, they evaluate its claims using Scripture, history, and logic, highlighting serious contradictions found in the books of Enoch and Jubilees. The discussion exposes calendar inconsistencies, added holidays, and theological errors that conflict with both the Old and New Testaments. If you’ve heard claims about the “ancient” Zadok Calendar and wondered whether they hold up biblically, this episode offers a clear, thoughtful, and Scripture-based response.
