The year 2017 will see the first centennial commemoration of the Reformation to take place during the ecumenical age. It will also mark fifty years of Lutheran - Roman Catholic dialogue. As part of the ecumenical movement, praying together, worshipping together, and serving their communities together have enriched Catholics and Lutherans ... The spirituality evident in interconfessional marriages has brought forth new insights and questions. Lutherans and Catholics have been able to reinterpret their theological traditions and practices, recognizing the influences they have had on each other. Therefore, they long to commemorate 2017 together.
