Gabriel of Beth Qustan was a 7th-century Syriac Orthodox bishop and monk who served the community in Tur Abdin. Born in the village of Beth Qustan, he entered the Monastery of Qartmin as a monk before rising through the ecclesiastical ranks to become its abbot and the Archbishop of Dara. During his leadership, he likely negotiated the rights of his church following the Muslim conquest of Mesopotamia. He is remembered as a thaumaturge, a title reflecting the numerous miracles attributed to him during his lifetime and after his death.
Life and ministry
After joining the Monastery of Qartmin, Gabriel was ordained a deacon and later a priest. He assumed leadership of the monastery and the archdiocese in 634, succeeding Daniel Uzoyo. As a prominent leader, he may have interacted with Caliph Umar to secure the church's position in the region. His tenure was marked by various reported miracles, including the resurrection of several individuals, such as a widow's son and a friend who served as an abbot.
Veneration and legacy
Following his death in 648, his funeral was attended by thousands of clergy. In 774, monks exhumed his remains to seek protection from a plague, leading to the relocation of his right hand. He eventually became the patron of his monastery, which by the late 15th century was renamed the Monastery of Saint Gabriel. He is commemorated as a saint in the Oriental Orthodox tradition on 23 December.
