The Nicene Dossier in Western Syriac Canonical Collections

This paper examines the reception of the 325 Synod of Nicaea in late antique and early medieval Western Syriac collections of canon law. Particular attention is paid to a collection that originated in the 7th century and probably goes back to the multilingual miaphysite scholar Jacob of Edessa. Like many oriental collections of canon law, it is based on the Greek Corpus Canonum of the Church of Antioch. However, compared to most witnesses of the Corpus Canonum tradition, it offers a considerable number of additional documents related to the Synod of Nicaea. It includes the letter in which Constantine moved a synod planned in Ancyra to Nicaea, which is only preserved in West and East Syriac collections. Furthermore, it offers the anti-heretical appendix to the Nicene Creed (Appendix Antiochena) in a more detailed version, which is otherwise only preserved in a single Coptic manuscript. In addition, it contains a Nicene decree on the date of Easter, which is preserved in Greek in the Synagogue of John Scholasticus, deprived of its context. Finally, it contains the letter of the Nicene Synod to the Church of Alexandria, which is otherwise preserved in distinctly different contexts, always outside of the Corpus Canonum tradition. The collection is also the only witness for the letter of the Synod of Antioch (324/25). It is erroneously attributed not to the Synod of Nicaea, but to the Church Council of Antioch (341), but an accompanying commentary relates it to the Nicene Creed. The paper begins with an introduction to the structure and history of the collection, all the manuscripts of which can be traced back to an archetype that can be located in Tur-‘Abdin during the eighth century. The individual documents are then presented and categorised in terms of their transmission history. It can be shown that they were already found in the Greek model of Jacob of Edessa and, if they were not compiled by the editor himself, were taken from the archive(s) of the fifth-century Church of Antioch. The Syrian editor was interested in them as historical-canonistic documents, as well as for philological reasons. Together, they provide a comprehensive picture of the Nicene Synod, which is analysed in detail in the article. In the process, the effects of the collection in Michael the Syrian’s chronicle also come into view.

Curriculum Vitae

Prof. Dr. Matthias Simperl was born in Schwäbisch Hall (Baden-Württemberg, Germany) in 1989. After graduating from high school, he studied Catholic theology, philosophy and history in Tübingen, Munich, Rome and Augsburg. In 2015, he completed these studies with a diploma in Catholic theology. For this, he submitted a thesis on the early redactional history of the Roman Liber pontificalis. He then studied classical philology and editorial studies in Fribourg (Switzerland), where he completed his Master of Arts in 2018 with a thesis on Gregory of Nazianzus’ speeches directed against Julian the Apostate. In his doctoral thesis, he re-edited the letter of the Synod of Antioch (324/25), analysed the tradition and defended the authenticity of this document, which is of great importance for our understanding of the immediate history of the Council of Nicaea. The work was accepted by the Faculty of Catholic Theology at the University of Augsburg in 2023 and subsequently honoured with several awards. From 2016 to 2024, Simperl was a research assistant at the Chair of Church History with a particular focus on Ancient Church History and Ancient Church Theology at the Catholic Theological Faculty of the University of Augsburg. Since October 2024, he has been on leave from this position and is the temporary holder of the vacant chair until further notice.
