The Catholic movement of Jansenism rose to great popularity in the
latter half of the 1600s, despite staunch opposition from the Jesuit
orthodoxy. A 1653 papal bull made a five-point charge of heresy against
the Jansenists, with official tolerance of the movement ending in a
second bull of 1713.
Among the beliefs of the Jansenists, first
expressed in the writings of Cornelius Jansen, was that the Second
Coming would occur in 1733. Jansen died on this date in 1638.
