Abstract: | This text is an edited version of a keynote address given in Paris on 12 March 2019 to a colloquium on “Justice and Justification” organized by the Institute for Advanced Studies in Ecumenism (ISEO, according to its acronym in French) to mark the 20th anniversary of the Joint Declaration on the Doctrine of Justification (JDDJ) between Catholics and Lutherans in 1999. The article explores the origins and the reception of the JDDJ, as well as the opportunities it offers for Christians of all denominations today. It goes on to remember the Joint Commemoration of the Reformation by Lutherans and Catholics in 2016 in Lund and Malmö, Sweden, and how this was influenced by the insights gained from the Lutheran–Mennonite dialogue. The address notes how since the signing of the Joint Declaration in 1999, three other Christian World Communions have joined the declaration and highlights various upcoming anniversaries, including the 500th anniversaries of the Diet of Worms in 2021, and of the Augsburg Confession in 2030. |
