The North American Academy of Ecumenists is gathering this September at Princeton Theological Seminary, widely regarded as one of the major twenty-first-century centers for the study of World Christianity: investigation and interpretation of the diversity of Christian communities worldwide, both in their historical development and in their contemporary forms. But PTS also bears an underappreciated legacy as ground zero for a pioneering, interdisciplinary framework for inductive, collaborative research into the dynamics of Christian division and the pathways of conflict transformation: Ecumenics.
This one-hour workshop, hosted as part of the 2026 NAAE gathering but open to the public and especially encouraged for graduate students, will put the NAAE’s Vice President (Prof. Raimundo Barreto) and Immediate Past President (Dr. Aaron Hollander), specialists in World Christianity and Ecumenics respectively, into conversation with one another and with participants on the mutual inclusivity of these fields. Taking each other’s recent monographs (Base Ecumenism and Saint George Liberator) as case studies, Barreto and Hollander will first explore the importance of activating methods and perspectives of World Christianity within spaces of ecumenical inquiry (like the NAAE itself) and the importance of revitalizing an interdisciplinary Ecumenics framework as a means of extending the reach and impact of studies in World Christianity. Then, they will open a discussion about workshop participants’ own experiences or interests in these fields of inquiry, considering what new possibilities might be stimulated by a more reflexive and strategic alignment between World Christianity and Ecumenics.
This event will have a hybrid format: in-person NAAE participants will join Barreto and Hollander on site at Princeton Theological Seminary; online conference participants and other attendees from the general public will receive a link to join via Zoom.
This program is free and open to the public, but online participants must REGISTER at: https://www.eventbrite.com/e/world-christianity-and-ecumenical-method-tickets-1997047215982?aff=oddtdtcreator
