Have the dialogue processes helped the German Catholic church advance? This question will be dealt with at a common conference of DBK and ZdK on 1 and 2 September at Wolfsburg in Mülheim a. d. R. Invalid style attribute.The conference shall examine how the results from the dialogue processes so far can be stored, how the developed dialogue culture can be further developed and how participatory structures can be implemented. I was invited to give a speech on the question if and how ecclesiology and organisational development can begin a dialogue on participation, subsidiarity and synodality. I am looking forward to interesting exchanges and impulses.
