The Society of Jesus is a religious order of men called Jesuits, who follow the teachings of the Catholic Church. Jesuit priests and brothers — also sometimes known colloquially as "God's marines" — are engaged in evangelization and apostolic ministry in 112 nations on six continents reflecting the Formula of the Institute (principle) of the Society. They are known in the fields of education (schools, colleges, universities, seminaries, theological faculties), intellectual research, and cultural pursuits in addition to missionary work, giving retreats, hospital and parish ministry, promoting social justice and ecumenical dialogue.
After the appearance of Grantville, the Society of Jesus was initially divided on its position on the time-displaced town. On an individual level, this division continued for years after the Ring of Fire. Some Jesuits had moved to Grantville, and had even become more-or-less Americanized; Saint Mary's Parish was noted for the number of Jesuits attached to it. However, other, more conservative Jesuits remained firmly opposed to what they saw as American heresy and even "deviltry".
After Cardinal Borja seized Rome in 1635, and had himself declared pope, the fugitive Father-General Mutio Vitelleschi, through his deputy Goschwin Nickel, declared that the Society would continue to view Urban VIII as the legitimate pope, and would continue to support him. Even so, if the Church schisms between supporters of Urban and supporters of Borja, it is possible that the Society will split as well.
