Jesuit Reductions
Cardinal Jules Mazarin strongly opposed Jansenists, both in Europe and abroad (with the Jesuit Reductions and the Jesuit China missions). Mazarin persuaded the pope to compel Jansenists to sign a formulary, to assent to "Ad sanctam beati Petri sedem", and to confess their faults. The Assembly of the French Clergy afterwards decided to compel all priests to sign an anti-Jansenist formulary, in which each one accepted the papal condemnation.
