This book was written by a bishop of Geneva who went on to be recognized as a Catholic Saint and Doctor of the Church after his death. Francis began preaching in the Calvinist region of Chablis, mainly addressing the poor. Preaching against Calvinist teaching was dangerous, but Francis survived two attempts on his life. Another time, he miraculously escaped death after meeting a wolf pack while traveling through the countryside. Despite the dangers, Francis continued to preach. Within four years, the region had returned to its catholic heritage. An Introduction to the Devout Life provides the reader with an inspiring example of faith and piety while demonstrating a fervent opposition to the doctrine of predestination.
