Autonomus was a 3rd-century Italian bishop and hieromartyr who lived during the era of the Diocletianic Persecution. Seeking to avoid the intense religious crackdowns in his homeland, he migrated to Bithynia in Asia Minor. In this new region, he served as the first bishop of Claudiopolis, where he focused his efforts on evangelization. His life and ministry eventually concluded with his martyrdom in 313.
Life and ministry
Born in Italy around 250, Autonomus fled to Bithynia to escape persecution. He became a prominent leader in the local Christian community, serving as the inaugural bishop of Claudiopolis. Through his missionary work, he spread the faith throughout the region before his death in 313.
Veneration
He is recognized as a saint in both Catholic and Orthodox traditions. The Eastern Orthodox Church commemorates his memory annually on September 12. As a hieromartyr, he is honored for his dual role as both a priest and a martyr.
