Jacob Baradaeus (/ˌbærəˈdiːəs/; Greek: Ἰάκωβος Βαραδαῖος; Arabic: مار يعقوب البرادعي; Syriac: ܝܥܩܘܒ ܒܘܪܕܥܝܐ, romanized: Yaʿqub Burdʿoyo), also known as Jacob bar Addai or Jacob bar Theophilus, was the Bishop of Edessa from 543/544 until his death in 578. He is venerated as a saint in the Oriental Orthodox Churches and his feast day is 31 July. Jacob's missionary efforts helped establish the non-Chalcedonian Syriac Orthodox Church, also known as the "Jacobite" Church after its eponymous leader, and ensured its survival despite persecution.
