Francis de Sales was a Bishop of Geneva and is honored as a saint in the Roman Catholic Church. He became noted for his deep faith and his gentle approach to the religious divisions. He is known also for his writings on the topic of spiritual direction and spiritual formation, particularly the Introduction to the Devout Life and the Treatise on the Love of God.
Introduction to the Devout Life enjoyed wide popularity, and was well received in both Protestant and Catholic circles, evidenced by its translation into all major languages of the day. It is typically categorized as a form of reading known as lectio divina (“divine reading”), based on the Christian monastic practice of spiritual reading.
