The article examines state-supported religious education and its consequences for civic attitudes in Indonesia and Israel, two democracies that grant religion a prominent place in the public sphere, particularly in education. The comparison reveals that while in Indonesia the state was able to gradually introduce a secular curriculum in religious schools and establish an accreditation system by which it could exert influence on the way religion is taught, in Israel, by contrast, state-funded religious schools over time became increasingly opposed to a mandatory ‘core curriculum’ of general studies.
