Jansenism is a theological movement within Catholicism that emerged in the 17th century, primarily associated with the teachings of Cornelius Jansen. It emphasizes the importance of divine grace and the belief that human beings are inherently sinful and cannot achieve salvation without God's intervention. Jansenists advocate for a strict moral code and often criticize the laxity they perceive in the practices of the Church. The movement gained significant traction in France, leading to conflicts with the Jesuits, who held opposing views on grace and free will. Jansenism was condemned by the Church in several papal bulls, but it continued to influence religious thought and practice, particularly in France and among certain intellectual circles.
