Step-by-step explanation:
Jansenism is the theological concept or movement that taught human nature was inherently corrupt and that the grace of God extended only to a limited number of individuals.
Developed by Cornelius Jansen in the seventeenth century, Jansenism was influenced by the ideas of St. Augustine and embraced the doctrine of original sin, emphasizing the need for divine grace for salvation. It held that human beings were morally incapable of achieving salvation on their own and that God's saving grace was bestowed only upon the predestined elect.
Furthermore, Jansenism rejected the idea of free will, arguing that human choices and actions were determined by God's sovereign will. It had a significant impact on Catholic theology and was declared a heresy by the Catholic Church in the early eighteenth century.
