In the Christian tradition
Two major saints carry the name Ignatius. Ignatius of Antioch (c. 35-108) is the second-century bishop and martyr whose seven letters written on his journey to martyrdom are among the earliest Christian writings outside the New Testament. Ignatius of Loyola (1491-1556) is the Basque founder of the Society of Jesus (the Jesuits), the author of the Spiritual Exercises that have shaped Catholic spirituality across five centuries. The Catholic calendar commemorates Loyola on July 31 and Antioch on October 17.
