In April and May 2025, an ecumenical seminar was convened for the second time in Assisi, Italy. They met under the banner of The Feast of Creation and the Mystery of Creation: Ecumenism, Theology, Liturgy, and Signs of the Times in Dialogue to continue a conversation begun a year earlier.
Organized by the Laudato Sì Research Institute of the Roman Catholic Church in partnership with the Anglican Communion, Lutheran World Federation, the World Communion of Reformed Churches, the World Council of Churches, and the World Methodist Council, the seminar met to examine the history of Christian engagement with the creation story, described in the book of Genesis, in the context of the growing climate justice movement. They developed a proposal that a creation season be incorporated into the liturgical calendar to run from A Feast of Creation on September 1 through to October 4, the Commemoration of Francis of Assisi.
Registration for ILS 2026 is open!
From the ILS Newsletter: The 77th meeting of the Institute of Liturgical Studies will consider the possibilities of such a festival and season. We will reflect on creation, incarnation, and Jesus’s death and resurrection, all received by us through the created materiality of our sacramental life together. Furthermore, we will examine how petroleum culture has influenced our sacramental life and begin to envision ways to counter its impact. A model lectionary will be used, and sample liturgies will be celebrated.
