The Council of Nicaea in the Historiographic Writings of the Church of the East

The early reception of the Council of Nicaea in the Church of the East has usually centered around the Synodicon Orientale with the 410 Synod of Isaac’s adherence to its decisions and canons, as well as a form of its creed. This presentation seeks to provide a perspective on the reception of Nicaea in the time afterwards, focusing on the historiographical sources of the Church of the East. Beginning with the Syriac Ecclesiastical History of Barhadbeshabba ʿArbaya in the sixth century and concluding with the great Arabic syntheses of the early second millennium, this presentation discusses the representation of the Council of Nicaea in ten major and minor historiographical sources of the Church of the East. Identifying the major themes associated with Nicaea in these sources helps uncover the role of the council in shaping the Church of the East’s historical memory, offering insights into its self-definition and its relations to other ecclesial bodies. This offers, in turn, a distinct lens on the council's impact and ecumenical legacy in a church situated outside the Roman Empire and with a different ecclesiastical structure.
