Q. 1. What is the history of the "Jansenism" heresy?

A. 1. The "Jansenism" heresy was a movement that persevered in the Catholic Church for over 100 years. It found its origin in the Counter-Reformation after the Council of Trent (1545–1563). "Jansenism" emphasized original sin, human depravity, the necessity of divine grace, and predestination.

This movement originated from the writings of the Dutch theologian Cornelius Otto Jansen. Jansenism formed a distinct movement within the Roman Catholic Church from the 16th to 18th centuries.

On May 31, 1653, Pope Innocent X condemned this movement in the Papal bull "Cum occasione."
