Work dossier · summary and historical context
Letter 20 of Ishoʿyahb III, patriarch of the Church of the East (649–659), is a theological reply to Mar Iazdshapur defending dyophysite Christology against perceived miaphysite tendencies. Written in Syriac during the early Islamic period, the letter addresses the duality of persons in Christ, a central issue in the Christological debates of the Church of the East. It employs ascetic and rhetorical imagery typical of Syriac literature, such as the 'furnace of love' and 'herald of the speaker,' and reflects a pastoral tone urging confidence in orthodoxy. The letter survives in manuscript collections of Ishoʿyahb's correspondence, used for theological instruction within the Church of the East.
This letter is a key witness to the Christological debates of the Church of the East in the early Islamic period, showing how dyophysite theology was articulated and defended. It also illustrates the literary and rhetorical style of Ishoʿyahb III, a major figure in Syriac Christianity. The letter's preservation in manuscript collections highlights its role in theological instruction, and its technical Syriac terms (e.g., qnoma, kyana) are crucial for understanding the nuances of East Syriac Christology.
Ishoʿyahb III served as patriarch of the Church of the East from 649 to 659, a period following the Arab conquests of the Sasanian Empire. The letter was likely written during his patriarchate, addressing ongoing Christological controversies that persisted after the Islamic conquests. The Church of the East, centered in the Sasanian and early Islamic realms, maintained a dyophysite Christology (emphasizing two natures in Christ) against miaphysite positions. The letter is addressed to Mar Iazdshapur, a bishop or monastic leader, and reflects the use of correspondence for theological instruction and pastoral guidance. The text is preserved in Syriac manuscripts of the Church of the East, later compiled into collections of Ishoʿyahb's letters, which were transmitted through monastic and ecclesiastical networks for doctrinal education.
