The Great Heresies

In this insightful examination, Hilaire Belloc explores five of the most destructive heretical movements that have impacted Christian civilization: Arianism, Mohammedanism (Islam), Albigensianism (Cathar), the Reformation (Protestant), and the modern phase. He details their origins, spread, and ongoing influence up to 1936, with particular emphasis on Islam, where he notably forecasts a resurgence of jihadist aggression toward the West.
