SalveMariaRegina"A Diocletian may succeed in causing a four years’ vacancy in the See of Rome; antipopes may arise, supported by popular favor, or upheld by the policy of emperors; a long schism may render it difficult to know the real Pontiff among the several who claim it: the Holy Ghost will allow the trial to have its course, and, while it lasts, will keep up the faith of His children." Abbot Guaranger
