Heresy & Apostasy
What happens when a believer departs from accepted doctrine? Every tradition has mechanisms for defining orthodoxy and responding to deviation. Heresy and apostasy raise fundamental questions about community boundaries, the nature of truth, and whether faith can be compelled or must be freely given.
