Francis de Sales (French: François de Sales; Italian: Francesco di Sales; 21 August 1567 – 28 December 1622) was a Bishop of Geneva and is honored as a saint in the Catholic Church. He became noted for his deep faith and his gentle approach to the religious divisions in his land resulting from the Protestant Reformation. 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.
The Roman Catholic Church celebrates St. Francis de Sales’ feast on 24 January, the day of his burial in Annecy in 1624. From the year 1666, when his feast day was inserted into the General Roman Calendar, until its 1969 revision, he was celebrated on 29 January, a date still observed by some Traditionalist Catholics.
