Today we explore the legacy of one of the most powerful papal names in Church history—Leo. With the election of Leo the Fourteenth, many are asking what it means to choose that name. We walk through the legacies of Leo the First (Leo the Great), Leo the Third, Leo the Tenth, and Leo the Thirteenth—tracing a line from theological clarity and imperial coronations to Reformation crisis and modern renewal. This isn’t just Church history—it’s our story, and each Leo leaves behind a mark: some healed, some divided, some saved cities, and some changed the Church forever.
