Article 7 (3) of the German 'Grundgesetz' gives space for the organizational and conceptual design and further development of religious education in schools. Denomination-oriented religious education constitutively includes the fundamental right to negative as well as positive freedom of religion. It also opens a wide range of possibilities for participation for smaller religious communities as well as for non-religious groups. Starting from the basic constitutional norm, the volume develops perspectives for a sustainable religious education in the light of various religious and secular communities and explores possibilities for cooperation between religious education and its substitute subjects such as ethics, philosophy or 'values and norms'.
