Public Theology is by self-definition and, according to general expectations, supposed to contribute to the debate on social issues. But reality shows that there is a limit when it comes to putting theological ideas into practice. This text discusses the challenges and opportunities with reference to the example of ‘good’ decision-making in an attempt to define the specific function of Public Religious Pedagogy (“Öffentliche Religionspädagogik”) in this context. This contribution thus advocates a wider notion of Religious Pedagogy, while the discipline in Germany is usually taken to focus on religious education at schools or in congregational settings.
