A combination of the following: A fixed coherent set of beliefs, usually religious, which form a pattern of religious opinions and rules; ritual and habitual behaviour; group or community organizations and structures (hierarchy, leadership, buildings etc); with a basis in key texts such as the Bible for Jews and Christians and the Koran for Muslims. There is usually a sense of the other, the supernatural or the ultimate in these systems although not always. Secular belief systems such as humanism and communism do not have this transcendental aspect. See also Value system, World View.
