"Challenges" is the title of the new textbook series for Protestant religious education at secondary schools in Bavaria. "Challenges" shapes religious education. And religious education presents students with this challenge: to get to know the discourse about God and Jesus and to engage with it independently, in groups, and under expert guidance. A genuine secondary school textbook, serious, clear, and open, consistently aligned with the new LehrplanPLUS for Bavaria, tailored to the target audience and tested in practice.
