The Heretics and Schismatics of the Early Church
Marcion, Valentinus, Arius, Montanus, Donatus, Sabellius and the teachers around them — the losing side of every early controversy, named by the writers who beat them.
Almost everything here is known from hostile witnesses. Where a heresiarch’s own words survive, usually as a quotation inside a refutation, the archive gives them; where they do not, the entry says that the account comes from an opponent. Several of these people were bishops in good standing for decades before the label attached.
Judged by the standard of the councils that condemned them, not by any modern one. Figures whose orthodoxy was merely questioned, and figures later rehabilitated, are marked in their own entries rather than filed here.
