Ut Unum Sint Lecture Series

“The movement promoting Christian Unity is not just an ‘appendix‘ which is added to the church’s traditional activity.”

Pope John Paul II – Ut Unum Sint

The year 2020 will mark 25 years since Pope John Paul II’s Ecumenical Encyclical Ut Unum Sint (That They May Be One). This was a landmark document in the history of the Catholic Church’s communication and friendship with other Christian Traditions. In the lead up to the 25th anniversary next year, ACEIR will be arranging a series of three lectures reflecting on the document. The series will invite speakers from several different Christian Traditions, along with members of the Catholic Church, to reflect on the document, the ecumenical imperative, and the true meaning of the Christian call to fraternity and unity.

Lecture I

Ecumenism in Australia: Yesterday and Today

The first lecture in the series will outline the document, discussing the key points in their historical and theological context. This overview will then be used as a foundation for discussion of the ecumenical situation in Australia, both in the past and the present. There will be a brief Q&A session after the speakers.
