Named after Fr. Elliott Bernard Allen (1921-1981), who was the founding Dean of Faculty of Theology at St. Michael’s College, the Institute was created in 1991 in response to the growing environmental crisis.
The first Director, Fr. Stephen Dunn, C.P., through the inspiration of the work of cultural historian Fr. Thomas Berry (1914-2009), developed a certificate program so students at the TST could acquire a specialization in Theology and Ecology while completing their graduate degree.
Since 1991, students have also been able to complete masters and doctoral level theses in eco-theology (including eco-spirituality, eco-feminism, and eco-ethics) as well as interdisciplinary theses involving eco-theology—a pioneering accomplishment of the Elliott Allen Institute.
In addition to courses about the relationship between theology and ecology, the Institute hosts public lectures, bringing a variety of experts into dialogue with theologians to creatively explore ecological challenges.
Lectures have been delivered by: Thomas Berry, Brian Swimme, Mary Evelyn Tucker, John Grim, Rosemary Radford Reuther, Heather Eaton, Anne Marie Dalton, Christopher Key Chapple, Chung Hyun Kyung, Theodore Roszak, Stephen Bede Scharper, Edmund O’Sullivan, John Haught, Dieter Hessel, Dorothy Golden Rosenberg and Celia Deane-Drummond among others.
After Fr. Dunn retired in 2001, Dr. Dennis O’Hara became the Director. Dr. Hilda Koster took over in 2021 – the third Director to lead the Institute.
Since its inception, the Institute has enjoyed a close relationship with the Passionists of Canada, especially at the former Holy Cross Centre for Ecology and Spirituality at Port Burwell, Ont. It is also closely aligned with the Sisters of the Congregation of St. Joseph, especially at their Villa St. Joseph Ecology and Spirituality Centre in Cobourg, Ont.
Through these partnerships, the work of the Institute was enlarged and enhanced. The student members of the Institute have expanded their classroom education to the more natural settings of these retreat centers. Today, this collaboration continues at St. Gabriel’s Passionist Parish in Toronto through the monthly eco-sabbath gatherings and the annual Advent-Solstice Evening of Reflection, as well as an annual course in eco-praxis at Villa St. Joseph Ecology and Spirituality Centre in Cobourg.
In 2012 a brief video about the mission and history of Elliott Allen was made, including unique archival material of a lecture by Fr. Thomas Berry.
