On April 22, 1541, Ignatius Loyola and his associates became monks. Unlike other orders, the Jesuits take four, not three, vows - non-covetousness, chastity, obedience, plus fidelity and obedience to the Pope. Perhaps that is why they are in the first roles in the Vatican: they manage the Gregorian University and the Oriental Institute, and the activities of Vatican Radio. In the 18th century, the order was abolished for trading operations in the West Indies (it was then that Jesuit teachers poured into Russia), but subsequently revived. The result: more than 500 schools, about 130 colleges and universities, 55 seminaries and dozens of social service projects around the world.
