In the nearly four years since he was elected, Pope Francis I has achieved the singular distinction of bringing the Roman Catholic Church within sight of Schism. Even if a formal split is still unlikely, the de facto division widens every day his papacy continues. Like Martin Luther, who turned northern Europe into a battleground of Protestants versus Catholics – and whom the Pope, in his uniquely perverse way, made such a point of admiring recently – Francis is causing a rift between those who support him and those who put up with him, for now.
