Pope Leo the Fourteenth is admitted to Rome’s Gemelli Hospital today to undergo surgery to remove a small nodule in his lung. With doctors advising about a week of medical rest, the Prefecture of the Papal Household has suspended all public and private papal audiences through October twentieth.
Key events on the Vatican calendar have already been rescheduled. Notably, Cardinal Luis Antonio Tagle will preside in the Pope’s place over the closing Mass marking the tenth anniversary of Amoris Laetitia.

This pause raises a fundamental question: Who governs the Catholic Church when the Pope is in the hospital? Can the cardinals take over?
The answer lies in the Church’s Canon Law.
Under Canon 331, the Bishop of Rome retains supreme, full, and direct authority over the Universal Church. A hospital stay does not transfer this power to anyone else.
Day-to-day administrative matters continue seamlessly through the Roman Curia—including the Secretariat of State and the various dicasteries. Under Canon 360, these offices operate in the Pope’s name to carry out routine governance. However, matters reserved exclusively for the Pontiff simply await his recovery.
Canon 335 addresses situations where the Roman See becomes vacant or completely impeded. In such circumstances, Church law strictly dictates that nothing may be altered in the governance of the Universal Church, and special norms must be observed. However, a routine hospital stay is not classified as an impeded see, nor does it trigger Sede Vacante—which applies solely to a pontiff’s death or valid resignation.
While cardinals frequently represent the Pope at liturgies or diplomatic duties, they cannot assume his governing authority. The Church’s constitutional structure remains fully intact, as millions of faithful worldwide unite in prayer for the Holy Father’s swift recovery.
