dogma

Dogma, in its broadest sense, is any belief held definitively and without the possibility of reform. It may be in the form of an official system of principles or doctrines of a religion, such as Judaism, Roman Catholicism, Protestantism, or Islam, the positions of a philosopher or philosophical school, such as Stoicism, and political belief systems such as fascism, socialism, progressivism, liberalism, and conservatism.
