On this path, we Catholics and Lutherans, from several countries, together with various communities sharing our ecumenical journey, reached a significant step when, on 31 October last, we gathered together in Lund, Sweden, to commemorate through common prayer the beginning of the Reformation. This joint commemoration of the Reformation was important on both the human and theological-spiritual levels. After fifty years of official ecumenical dialogue between Catholics and Lutherans, we have succeeded in clearly articulating points of view which today we agree on. For this we are grateful. At the same time we keep alive in our hearts sincere contrition for our faults. In this spirit, we recalled in Lund that the intention of Martin Luther five hundred years ago was to renew the Church, not divide her. The gathering there gave us the courage and strength, in our Lord Jesus Christ, to look ahead to the ecumenical journey that we are called to walk together.
