Pope St. John I

St. John I was Pope from 523-526.  He was very frail when he was elected to the papacy. Despite his protests, Pope John was sent by the Arian King Theoderic the Great—ruler of the Ostrogoths, a kingdom in present-day Italy—to Constantinople to secure a moderation of a decree against the Arians, issued in 523, of Emperor Justin, ruler of the Byzantine, or East Roman, Empire. Emperor Justin is recorded as receiving John honorably and promised to do everything the embassy asked of him, with the exception that those converting from Arianism to Catholicism would not be "restored" (i.e., allowed to retain their place in the Catholic hierarchy as deacons, priests, or bishops). Although John was successful in his mission, when he returned to Ravenna, Theoderic's capital in Italy, Theoderic had John arrested on the suspicion of having conspired with Emperor Justin. John was imprisoned at Ravenna, where he died of neglect and ill treatment. His body was transported to Rome and buried in the Basilica of St. Peter.

The Liber Pontificalis credits John with making repairs to the cemetery of the martyrs Nereus and Achilleus on the Via Ardeatina, that of Saints Felix and Adauctus, and the cemetery of Priscilla. Pope John I is depicted in art as looking through the bars of a prison or imprisoned with a deacon and a subdeacon. He is venerated at Ravenna and in Tuscany. His feast day is 18 May, the anniversary of the day of his death.
