The teaching about religions, being a necessary part of education, needs to be supported; and the 10th anniversary of «Toledo Guiding Principles on Teaching about Religions and Beliefs in Public Schools» (2007) serves as a good occasion to discuss this issue. The main pedagogical mission is to teach about the subject, not to generate values and meanings. Historically, these values and meanings were produced by religion, and the Church played a normative role, regulating the content of education and the entire life of the school.
