Fr. Gregory Waldrop and art historian Joseph Connors introduce themselves and open with a deceptively simple question: does the sacred require architecture at all, or can it exist in a mountaintop, a gathered assembly, a moment struck by lightning? They trace the idea through Hagia Sophia's dome — once described by visiting emissaries as making them unsure "whether we were in heaven or on earth" — and confront an uncomfortable truth running through nearly every celebrated sacred building: it was often built through violence, expropriation, or repurposed from another faith entirely, from the Parthenon to the Taj Mahal.
