Pope John I

Pope John I (Latin: Ioannes I; died 18 May 526) was the bishop of Rome from 13 August 523 to his death.

King Theoderic threatened that if John should fail in his mission, there would be reprisals against the non-Arian Christians in the West.

John proceeded to Constantinople with a considerable entourage: including his fellow bishops Ecclesius of Ravenna, Eusebius of Fanum Fortunae, and Sabinus of Campania.

[5] 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).

[7] Pope John I is depicted in art as looking through the bars of a prison or imprisoned with a deacon and a subdeacon.
