From the Catholic Encyclopedia: As has been explained under the title "Ignatius Loyola", the founder began his self-reform, and the enlistment of followers, entirely prepossessed with the idea of the imitation of Christ, and without any plan for a religious order or purpose of attending to the needs of the days. Unexpectedly prevented from carrying out this idea, he offered his services and those of this followers to the pope, "Christ upon Earth", who at once employed him in such works as were most pressing at the moment.
I don't deny that the Jesuits did the work that needed to be done but they did it within the Church.
