Origins and rise
Christopher was a native of Baghdad, originally bearing the name Isa. He was educated in rhetoric and was a skilled calligrapher, and he served in administrative roles within the Hamdanid sphere, including service connected to the court of Sayf al-Dawla, the emir of Aleppo. He came to Antioch around the time the see fell vacant on the death of Patriarch Agapius, and the local clergy and people elected him patriarch, an appointment the emir confirmed.
Patriarchate and works
As patriarch, Christopher undertook reform of the clergy and worked against corruption in church appointments. He was especially known for his care of the poor and oppressed: he negotiated with Sayf al-Dawla for reductions in the tax burden on Christian subjects and arranged for taxes to be paid on behalf of families who could not afford them. He also placed strong emphasis on education, founding schooling for the training of clergy and the instruction of children.
Sources describe his manner of life as marked by asceticism and prayer, and his generosity toward the needy earned him comparison with Saint Nicholas.
Political context and martyrdom
Antioch in Christopher's lifetime lay under the Hamdanid emirate of Sayf al-Dawla and on the frontier with the Byzantine Empire, which was steadily advancing in the region. When the emir died early in 967, the resulting instability allowed Christopher's enemies to move against him. They accused him of conspiring with the Byzantines and others against the city, and he was killed during the unrest of 967. His body was thrown into the Orontes River and later recovered.
After the Byzantine conquest of Antioch in 969, his remains were honored and buried in the church of Saint Peter, and he came to be venerated as a hieromartyr.
Sources and veneration
The most detailed account of his life was composed by Ibrahim ibn Yuhanna, a Byzantine official who had known Christopher in his youth. This Life of Christopher originally existed in both Greek and Arabic, but only the Arabic version survives. Christopher is commemorated as a hieromartyr in the Antiochian tradition; the dates associated with his commemoration include May 21, May 22, and May 23, the last reflecting the day of his martyrdom.
