Ignatius of Loyola, born Íñigo López de Oñaz y Loyola on approximately 23 October 1491, was a prominent Spanish Catholic priest and theologian. He is best known for founding the Society of Jesus, commonly referred to as the Jesuits, alongside six companions in Paris in 1541. As the first Superior General of this religious order, Ignatius played a pivotal role in shaping its mission and vision.
With a strong emphasis on missionary work and education, Ignatius introduced a unique fourth vow for Jesuits, which mandated obedience to the Pope. This commitment allowed the Jesuits to engage in various projects as directed by the pontiff, making them instrumental in the Counter-Reformation efforts.
Drawing from his experiences as a soldier, Ignatius focused on the spiritual development of his followers. He meticulously documented his approach in the Spiritual Exercises, published in 1548, which later evolved into what is now known as Ignatian spirituality. His teachings have had a lasting impact on the Catholic Church and beyond.
Ignatius was beatified in 1609 and canonized as a saint on 12 March 1622. His feast day is celebrated on 31 July, and he is recognized as the patron saint of the Basque provinces of Gipuzkoa and Biscay, as well as the Society of Jesus. In 1922, Pope Pius XI declared him the patron saint of all spiritual retreats.
