Ignatius of Loyola

Ignatius of Loyola, venerated as Saint Ignatius of Loyola, was a Basque Spaniard Catholic priest and theologian, who, with six companions, founded the religious order of the Society of Jesus, and became its first Superior General, in Paris in 1541.

Ignatius envisioned the purpose of the Society of Jesus to be missionary work and teaching. In addition to the vows of chastity, obedience and poverty of other religious orders in the church, Loyola instituted a fourth vow for Jesuits of obedience to the Pope, to engage in projects ordained by the pontiff. Jesuits were instrumental in leading the Counter-Reformation.
