Biography
Pope John III, originally named Catelinus, was the bishop of Rome from July 17, 561, until he passed away on July 13, 574. His thirteen-year leadership happened during a chaotic time when the Byzantine Empire tried to regain control over Italy, while the Lombards took over large areas of the region. John III managed these tricky political and military situations while upholding the papacy's spiritual authority.
During his time as pope, John III was under pressure from Byzantine Emperor Justinian I and his successors, who aimed to assert imperial power over church affairs. The pope worked to keep the church independent without directly clashing with Constantinople. His diplomatic efforts helped maintain stability in Rome even as many Italian cities fell to the Lombards or got caught in conflicts between the Byzantines and Lombards.
John III focused on looking after church properties and ensuring religious services continued despite ongoing warfare in Italy. He led the restoration of several Roman churches and provided help to refugees fleeing the Lombards in northern and central Italy. He also handled various theological debates and church administrative issues.
In the later part of his leadership, John III faced more pressure from the Lombards around Rome. While Rome itself stayed under Byzantine control, the pope had to manage his relationships carefully with both the imperial government and local military leaders. He died in 574 when Italy's political situation remained very unstable, with the Lombards strengthening their hold over much of the region.
Before Fame
Not much is known about Catelinus's early life before he became pope in 561. He was born in Rome in the late fifth or early sixth century, growing up just as control over the city shifted from the Ostrogoths to the Byzantines. He likely started his clerical career during the time of earlier popes, maybe under Pope Vigilius or Pope Pelagius I, who both faced big theological and political issues.
Becoming pope in the sixth century required a lot of experience within the Roman clergy and often meant dealing with tricky relationships with both the Byzantine imperial court and local Roman nobility. Catelinus would have seen the Gothic Wars that tore through Italy from 535 to 554, events that probably influenced his diplomatic style when he became pope.
