Pascal's "Provincial Letters" were not the only source of worry for the Jesuits in the seventeenth and eighteenth centuries. Many other calumnious publications appeared, such as "La morale des jésuites," "Disquisitions," "Nullités" etc., all of which had the single purpose of poisoning the public mind. The battle continued until an enforced peace was obtained by a joint order of the Pope and king prohibiting any further issues of that character from the press. That, however, did not check the determination of the Jansenists to crush the Society in other ways. Thus, as early as 1650, the Archbishop of Sens, who was strongly Jansenistic, forbade the Jesuits to hear confessions in his diocese at Easter-time, and three years later, he declared from the pulpit that the theology of the Jesuits was taken from the Koran rather than from the Gospels, and that their philosophy was more pagan than Christian. He called for their expulsion as schismatics, heretics and worse, and declared that all confessions made to them were invalid and sacrilegious. Finally, he proceeded to excommunicate them with bell, book and candle. They withdrew from his diocese but were brought back by the next bishop a quarter of a century later. Another enemy of the Society was Cardinal Le Camus of Grenoble, who forbade them to teach or preach; and when Saint-Just, who had been fifteen years rector of the college, complained of it to some friends, he was suspended and accused of a grievous crime of which he was absolutely innocent. When he brought the matter to court, Father General Oliva censured him for doing so and removed him from office. Santarelli, an Italian Jesuit, launched a book on the public which produced a great excitement. He proposed to prove that the Pope had the power of deposing kings who were guilty of certain crimes, and of absolving subjects from their allegiance. In Paris it was interpreted as advocating regicide, and was immediately ascribed to the whole Society; and it was condemned by the Sorbonne. Richelieu was especially wrought up about it. Poor Father Coton, the king's confessor, who was grievously ill at the time, almost collapsed at the news of its publication. The author had not perceived that the politics of the world were no longer those of the Middle Ages.
