St. John I
John · 523 – 526
The first pope to visit Constantinople, he was imprisoned and died a martyr on his return to Italy.
John I became pope in 523 and was sent by the Arian king Theodoric to Constantinople to negotiate with Emperor Justin I on behalf of the Arians. In Constantinople, John was received with great honor and even crowned the emperor. But when he returned to Ravenna, Theodoric — suspicious of John's warm reception in the East — threw him in prison, where he died in 526. The Church honors him as a martyr.
Why He Matters
John I was caught between two powers and paid for it with his life. His story is a reminder that holding to the faith sometimes means pleasing no one — and that faithfulness can cost everything.
