Culture, when understood as a macro concept, also includes religion. Religion constitutes an institutionalized aspect of culture, with its own sources of authority that regulate social behaviour. It is often based on the concept of transcendental authority, and most religions have codified normative systems. Change must be wrought within the religious hierarchy of the community and must conform to the religious dogma of the written sources. As a consequence, religions are often a haven against social and cultural change. In all religions, there are movements that resist any change to the patriarchy and the status of women and girls in the family. Conversely, non-gender-based discriminatory practices, including some previously defended in the name of culture and religion, such as slavery, have been delegitimized or abandoned as values and ethics have evolved.
