There is one of their pupils who, at this time, though a man of unusual ability, brought sorrow not only on the Society but also on the universal Church: Marc Antonio de Dominis. He was a Dalmatian, whose family had given a Pope and many illustrious prelates to the Church. He followed the course of the Jesuit college in Illyria, and amazed his masters by the brilliancy of his talents. He entered the novitiate, and contrary to the practice of the Society was immediately made a professor of sacred eloquence, philosophy and mathematics. Crowds flocked to hear him; meantime he distinguished himself in the pulpit. Apparently he was a priest when he became a novice. The fame he acquired, however, turned his head and he left the Society to become a bishop, and later an archbishop, in Dalmatia. But his utterances soon showed that he was at odds with the Church. He was with Venice in its quarrel with the Pope, and then relinquishing his archbishopric, he fled to England, where he was received with enthusiasm by James I, who kept him at court, showered rich benefices on him and made him Dean of Windsor. There he wrote a book entitled "De republica christiana" (1620), which denied the primacy of the Pope. Pursued by remorse he went to Rome and at the feet of Gregory XV implored forgiveness for his apostasy. But his repentance was feigned. His letters to certain individuals showed that he was still a heretic, and he was imprisoned in Sant' Angelo, where he died in 1624, giving signs at the last moment of genuine repentance. The long Generalate of Vitelleschi was clouded by one disaster: the expulsion of the Jesuits from the Duchy of Lorraine. They had opposed the bigamous marriage of the duke, but his confessor, Father Cheminot, claimed that there were sufficient grounds for invalidating the first marriage, and took the opposite side. He was expelled from the Society or left it.
