List of known heretics

 * Fal 'Chavamee was named a heretic for his refusal to accept the Covenant religion. As a result, his wife Han was executed, and after 'Chavamee and a high-ranking Sangheili named Haka died by each others' hand in a duel, 'Chavamee's rank of Arbiter was changed from a gloriously honorable rank of prestige to a rank granted only to Sangheili who have disgraced themselves, that they might regain their honor in death by undertaking suicidal, yet important missions for the good of the Covenant.
 * Upon learning that the human species had been chosen to be the Reclaimers of the Forerunners' legacy, the Prophet of Truth, in order to protect the current status of the Covenant, and therefore his own personal power, declared that the entire species was an affront to their gods and should be eradicated. Thereafter, humans were referred to as heretics by the Covenant because of this claim.
 * Sesa 'Refumee, leader of an artifact retrieval team, encountered the Forerunner Monitor 343 Guilty Spark in a Threshold gas mine, and discovered through conversation with him that the true purpose of the Halo Array was to wipe out all life in the galaxy, not to help true believers ascend to a higher plane of existence. Thereafter, 'Refumee and his soldiers began an open rebellion against the Covenant, which would have been grounds enough for the label of Heresy, but he also openly preached that the Great Journey was a lie, resulting in the creation of an Arbiter (see below) for the specific purpose of silencing him.
 * Thel 'Vadamee, the commander of the Fleet of Particular Justice, failed to prevent the destruction of a Halo ring by John-117. This failure was deemed heresy, and he was branded with the Mark of Shame and sentenced to death. However, the Hierarchs of the Covenant chose to name him the latest successor to the rank of Arbiter instead of simply killing him, that he might regain his honor and serve the Covenant further.
