As a Christian ecumenical religious order, we are committed to authentic ecumenism and seek ecumenical dialogue with all Christian Churches and charitable dialogue with all religions of good will.

As an order founded upon the 1931 Bonn Agreement between Anglicans and Old-Catholics, our commitment to ecumenism is rooted in our theology of baptism. Indeed, through the mystery of baptism, we all enter into the Divine life; and through our baptism, we are all one in Christ.

The Hans Küng Center for Ecumenism at St. Willibrord Priory hosts ecumenical and inter-religious conferences, lectures, courses and workshops concerning Christian unity and Old-Catholic spirituality in addition to retreats, days of recollection and ecumenical fellowship for clergy and lay people. 

The Center was named in honor of The Rev. Prof. Dr. Hans Küng, the renowned German Catholic theologian. In 2013, Professor Küng was awarded the Doctor Divinitatis degree, honoris causa, by the Collegium Augustinianum.
