Abstract: | This article explores why the Lutheran/Roman Catholic commemoration of the Reformation in 2017 is an ecumenical challenge par excellence. In particular it contrasts the context of the 2017 commemoration with that of previous centenaries and goes more deeply into this by analysing the dialectics of centenaries both in general and with respect to this very special centenary. It also describes major changes in the relationship between Protestants and Catholics, presenting other main aspects of the new context in which that commemoration is taking place in 2017, and addressing different aspects of commemoration. It offers an analysis of how the Catholic/Lutheran Commission on Unity overcame the hindrances to a common commemoration and celebration in its document ‘From Conflict to Communion’, opening the way for a twofold commemoration, both in joy and gratitude, and in lament and confession of guilt. The article also focuses on five ecumenical imperatives which this document offers, not only looking back, but also looking forward, committing Catholics and Protestants to continue their way from conflict to communion. It concludes by describing the highly remarkable service of Common Prayer, which took place in Lund Cathedral, with Pope Francis, for which the above document prepared the way and formed the basis. It becomes clear how theological preparation and the Common Prayer in Lund concurred in making possible a historic ecumenical commemoration and celebration of the Reformation. |
