The basis for the work at hand is a look at current and future societal challenges in living together in communities. Public Theology claims to offer an important contribution as far as the overcoming of societal issues is concerned. The aim of this research is to shed light on this theoretical claim by relating it to a practically applied project while asking the question how the existing challenges can be dealt with. It is explicitly about participatory structures and their advancement. Participation is considered a key element for functioning communities in society. The advancement of participation for young people contains an element of activation, support and care. This research investigates which access paths the young people chose for their participatory engagement, how these are designed and experienced, and finally, how these paths can be strengthened and developed. The response to these questions resulted in concrete courses of action for the research project STC-Bremen, and furthermore, in generalized interpretations which can aid the development of other fields of action. ; Philosophy, Practical and Systematic Theology ; M.
