Matthew Neumann

Graduate Candidate in History of the Christian Tradition



Matthew Neumann is a doctoral candidate in the History of the Christian Tradition. His research interests include Trinitarian theology and relations between the Roman Catholic and Eastern Orthodox traditions as they developed and separated from one another in the medieval and early modern periods. His broader interests extend to the history of the doctrines of God, Christ, the Holy Spirit, and salvation.


Matthew’s  dissertation, “‘More Orthodox than Thomas:’ John Duns Scotus, Gennadios Scholarios, and the Filioque,” will give a critical analysis of the theology of the Holy Spirit in the late Byzantine theologian Gennadios Scholarios (c. 1400 – c. 1472), especially as it relates to his reception of the Franciscan theologian John Duns Scotus (c. 1265-1308) and thecontroversy between medieval Greek and Latin Christianity concerning the procession of the Holy Spirit. What makes Scholarios’s response to the controversy unique is his ability to draw on a wider range of Greek and Latin, early and medieval, sources than almost anyone else. His reception of Aquinas is well-known, but he is also one of the few Byzantine thinkers who had direct access to the works of Scotus, whom he mentions by name. The dissertation will seek to bring out some of the neglected aspects of these two late medieval theologians and see what potential they provide for a historical approach to ecumenical issues.


Matthew holds a Master of Arts in Religious Studies from the University of Chicago, a Master of Divinity from Princeton Theological Seminary, and a Bachelor of Arts in History and Biblical and Theological Studies from Wheaton College, where he also completed a Certificate in Early Christian Studies. He lives in Dallas with his high school sweetheart, Ashley Acevedo Neumann, and their dog. They enjoy traveling and exploring new places together, and have appreciated having warmer winters than they did in their Midwest hometowns.
