The Historic Installation of Pope Leo I the Great

On this significant day in 440 AD, a momentous event occurred in the history of the Catholic Church—the installation of Pope Leo I, also known as Leo the Great. Leo was the first pope in history to emphasize the authority of the papacy as the true successor of Saint Peter, establishing a foundation for future leadership within the Church.
