We are pleased to invite you to the 59th study and networking day of the Catholic National Commission for Ecumenism, which will take place on Saturday, 7 November 2026, from 9:30 a.m. to 4:30 p.m. at the Interdiocesan Centre (Guimardstraat 1, 1040 Brussels), focusing on the following topic:<\/p>\n\n\n\n
One in Christ, sent together<\/strong><\/p>\n\n\n\n In collaboration with Missio Belgium, we have chosen the theme of the 100th World Mission Day for this year. As Pope Leo stated in his invitation, if we truly wish to become a missionary Church, we must strengthen our ecumenical commitment alongside other Christian Churches.<\/p>\n\n\n\n The speakers will explain how their respective traditions understand Christ\u2019s missionary mandate and to whom they feel particularly called to minister within our secularized Western society. During an ecumenical study day, we also aim to reflect on whether we can undertake this mission\u2014or certain aspects of it\u2014jointly with other Christian Churches. Some speakers will also address the diversity of our Christian communities and the presence of priests and pastoral workers from abroad who are serving here on mission.<\/p>\n\n\n\n This year, the main address will be delivered by Professor Dr Annemarie Mayer, Professor of Dogmatic at the Faculty of Theology in Trier and a member of the Joint Working Group between the World Council of Churches and the Roman Catholic Church.<\/p>\n\n\n\n In the afternoon, there will be contributions from other Christian churches.<\/p>\n\n\n\n On the study day the texts of the addresses will be available in Dutch and French and English. To register, please use the form hereunder.<\/p>\n\n\n\n \u2022 \n
