Bossey 80th Anniversary
For 80 years, the Ecumenical Institute at Bossey has been transforming lives and strengthening the global movement for Christian unity. Since its founding in 1946 by the World Council of Churches, Bossey has welcomed thousands of students, church leaders, and scholars from every region of the world, creating a unique community where dialogue, prayer, and shared learning transcend denominational, cultural, and national boundaries. Through this distinctive experience, generations of leaders have been equipped to serve as bridge-builders, peacemakers, and faithful witnesses in their churches and communities.
The 80th anniversary provides a unique opportunity not only to celebrate Bossey's remarkable legacy but also to reaffirm its continuing role in shaping ecumenical leadership for an increasingly fragmented world. In a world marked by deepening divisions and unprecedented global challenges, the Institute's mission is more vital than ever. This milestone is both a celebration of eight decades of faithful ecumenical formation and an invitation to partners, friends, and supporters to help ensure that Bossey continues to inspire, educate, and empower future generations of leaders committed to the unity of the Church and the flourishing of the world.

Special celebration in Bossey: 7 October
The commemoration begins on the evening of 6 October with an encounter between guests and the current student community. This opening moment would allow visitors, alumni, and friends of the institute to meet the newest generation of ecumenical leaders and to experience the spirit of community that has defined Bossey for eight decades.
The main celebration will unfold on 7 October. The day begins, fittingly, with morning prayers in the Bossey Chapel, grounding the anniversary in the shared worship that has always been central to the Institute’s life. A session of greetings follows, highlighting the “faces of Bossey” across 80 years including students, faculty, staff, and partners whose lives and ministries have been shaped by their time at the Institute. This is followed by a keynote address from the WCC general secretary, Rev. Prof. Dr Jerry Pillay, who will speak on “From Vision to Viability: Restating Bossey’s Mission for a Changing World,” offering both a theological reflection and a forward-looking mandate for the institute’s future.
A panel discussion will bring together representatives from the WCC’s Commission on Ecumenical Education and Formation, alumni, and former colleagues to reflect on Bossey’s evolving role in the global ecumenical movement.
The festive lunch that follows, accompanied by music or dance and the cutting of the anniversary cake, celebrates the intercultural richness that has always been Bossey’s hallmark. In the afternoon, alumni will share stories, testimonies, and reflections, culminating in the launch of the renewed Bossey alumni network, a key initiative designed to strengthen global connections among graduates.
The celebration will conclude with some symbolic act that could involve planting of an 80th anniversary tree and a group photo. This gesture embodies both memory and hope, rooting the legacy of the past while pointing toward the growth still to come.
Together, these events will form a celebration that honours Bossey’s history, celebrates its present, and commits the community to its ongoing mission of dialogue, justice, unity, and reconciliation.
Here you will find a selection of publications, articles and archive items about the history of the Ecumenical institute at Bossey.
The Story of Bossey
This brief yet lively history of Bossey, penned by Hans-Ruedi Weber and updated by Robert K. Welsh, delves into the roots and evolution of Bossey and its programmes, its place in the whole ecumenical movement, and the people who have invested creative energy into its growth and flourishing. The Story of Bossey reveals not only a life-changing venue for Christian encounter but a lens on the rapidly changing landscape of the larger church, the ecumenical movement, and indeed the world.
A Place to Remember
Bossey has remained in the memories of many people who have visited or studied here. This collection of essays is a testimony to the life altering experiences which have been taking place here since 1946. It continues to be a unique place and an important WCC programme that shapes the identity of the many students today that continue making a difference when they return home.
On 80th anniversary, Bossey celebrates “ongoing mission of dialogue, justice, unity, and reconciliation”
Fr Dr Lawrence Iwuamadi, academic dean of the World Council of Churches' Ecumenical Institute at Bossey, took time to reflect on the 80th anniversary of the “living laboratory” of ecumenism, and how its students are living into a future that brings hope in so many ways.
Suzanne De Diétrich in the WCC's Ecumenical Review regarding the first years of Bossey
"The Ecumenical Institute of the World Council of Churches opened its doors in October 1946. A brief survey of the first three years of its activity may be of interest to the readers of the Ecumenical Review. Figures never tell the whole story, but they act sometimes as an acid test: how far is the Ecumenical Institute truly Ecumenical — ecumenical in its recruiting, ecumenical in its life and teaching?"
Bossey, Bible and Culture, by Hans-Ruedi Weber
In his introduction to Hendrik Kraemer’s inaugural lecture for Bossey on 5 October 1946, W.A. Visser ’t Hooft wrote: “The programme of the Institute has three basic subjects: the Bible, the world, the universal Church.” He added that “to reconstruct the Church and to enable it to proclaim the message for which the world waits means in the first place that the laity become true ambassadors of the Church in their own milieu. The Institute must therefore devote itself very especially to the formation of the laity.”
Bossey: a short story of a great vision, by Rev. Dr Odair Pedroso Mateus
Less than one year following the end of World War II, the World Council of Churches (WCC) began the process of acquiring the Château de Bossey, with its three-floor 18th century mansion and a 12th century tower surrounded by small farms and vineyards on the slopes between the Jura mountains and the Lake of Geneva.
The Céligny congregation, Bossey, and the memories of Arnold Mobbs, by Rev. Dr Odair Pedroso Mateus
As Rev. Marc Gallopin welcomes the new Bossey students to the Reformed congregation in Céligny, Switzerland, this sunny Sunday, 13 October, the name of another Céligny pastor comes to my mind: Arnold Mobbs.
"Opening of the Ecumenical Institute" - Ecumenical Press Service, October 1946

Ronald Lawday: "An Impression of the Geneva Institute an Ecumenical Adventure" - The Record, March 1948
I have just returned from twelve weeks at Château de Bossey, the Institute of the World Council of Churches near Geneva. We were eighteen nationalities there: Swedish, Danish, Dutch, German, French, Italian, Czech, Hungarian, Ukrainian, Russian (in exile), Austrian, Swiss, Indian, Indonesian (including two Chinese), Peruvian, Brazilian, American, English—mainly youth leaders and teachers, met together for a course including study of the Bible, youth work, evangelism, and the World Church.
Ronald Lawday: "An Anglican Abroad" - Church of England Newspaper, April 1948
Recently I found myself, in common with about thirty other Christians, at the Ecumenical Institute, established in 1946 by the World Council of Churches. "Institute" scarcely conveys the right impression: situated within 30 minutes of Geneva by train, we found Château de Bossey; a beautiful 19th century mansion with terraces looking across Lake Leman to the hills of Savoy in the south; and, to the north, the Jura range. In the peace and happiness of a family atmosphere we settled down for 12 short weeks to think of the World Church, its problems and its possibilities.
Joanie: "Letter from the Château de Bossey" ' AYH Knapsack, Autumn 1947
Dearest Folks: Should have written you before, but I'm just beginning to realize where I am and that I am ... I've thought of you so often as we've talked of the problems of youth in 21 different countries - from Norway to South Africa, Germany to South India--and always we say "If only others could could know each other as we do..." ... and that's where youth hosteling comes in, and why I think of you.
Jo-Ann Price: "Chateau in Switzerland Now a Religious Center" - The Milwaukee Journal, March 1950
Since it was opened in October, 1946, no less than 500 Christian laymen and theologians have made their way along the narrow “avenue of trees” to the Chateau de Bossey near here. They have come from many countries and religious denominations to discuss how churchmen can come to grips with current affairs.
"Le Chateau de Bossey" - Church and Community, August 1950
Towards this end, some fifteen conferences have been held on subjects ranging from art to international law. These conferences last from five to ten days, and are essentially a round-table sharing of experiences and viewpoints by men and women engaged in a given field of work or research.
Bossey Grad School 53-54 Letters, March 1955
Dear friends, this "redactor" should probably begin by explaining the late date of this letter. You will remember that we had planned it for last September! Some letters did not arrive until after Christmas, although by now none of that matters since the major delay was personal. I'll not waste space by elaborating - use your imagination!
Bossey Newsletter Nr2, July 1955
Dear Friends, As many of you wrote me a letter in the past weeks, we can publish the second issue of our Newsletter earlier than it was planned. We all, I suppose, thinking about Bossey in these days, have in mind the departure of Prof. and Mrs. Kraemer, who will leave the Institute in August.
Bossey Newsletter Nr3, October 1955
Dear Friends, as I received so many letters, I will say only Hallo! to you all at the beginning of this Newsletter. Perhaps there will be some space at the end for me, to say some general remarks. - I received letters from Dr Paul and John Watson just after having written the 2nd issue. Now they may open this issue.
Harman Grieswood: "Christian communication word and image" - The Church of England Newspaper, June 1956
We must surely be impressed by two things—a deep sense of responsibility towards the danger of using modes of representation and communication which had become identified with purely secular ends and an awareness that whatever the difficulties all communication must somehow be used in Christ's service.
Robert S Paul: "Using the lay people" - The Congregational Monthly, July 1957
