Where Is Mor Yakup?
The Church of Mar Jacob stands in Nusaybin, the ancient city of Nisibis, on the very edge of the plain of upper Mesopotamia at the modern Syrian frontier. The wider region reaches north toward Mardin and east into the Tur Abdin, the heartland of Syriac Christianity, home to great monasteries such as Mor Gabriel. For many centuries Nisibis was a great frontier city, and the church stands as a monument to that long and storied past.
One of the Oldest Churches
The Church of Mar Jacob is counted among the very oldest churches anywhere in the world, its origins reaching back to the early fourth century — to the age when Christianity first emerged from persecution into the open. Built of stone, with an ancient chamber that served as a baptistery and the crypt of its founder beneath, the church has endured in some form through seventeen centuries of war, empire, and change. Recent archaeological work has uncovered and conserved its ancient remains, revealing the depth of its history layer by layer.
Jacob of Nisibis
The church is named for and founded by Jacob of Nisibis, a revered bishop of the city in the early fourth century, honoured as a saint across the Christian world. He was among the bishops who took part in the great council that shaped the early Christian creed, and many traditions and miracles gathered around his name. He was remembered as the protector of his city and the teacher of famous pupils. His tomb within the church made it a place of pilgrimage, and his memory has been cherished by the Syriac Christians of the region down to the present day.
The School of Nisibis
Nisibis was home to one of the most celebrated centres of learning of the ancient world — the School of Nisibis — closely bound to the church and the Christian community of the city. Here scholars studied scripture, theology, philosophy, and science, and the school became a beacon of knowledge that influenced learning across the East. The great early Christian poet and teacher Ephrem the Syrian was associated with Nisibis before its school rose to its greatest fame. The legacy of this learning is part of what makes Mor Yakup and its city so important in the history of the region.
