Organized religions may include a state's official religion, for example reified by a state church; however, most political states have any number of organized religions practiced within their jurisdiction. Due to their structured, standardized, and so easily proliferated form, organized religions comprise many of the world's major religious groups. The Abrahamic religions are all largely considered organized (including Christianity, Islam, Judaism and the Bahá'í Faith), as well as some schools of thought within Indian religions (for example, some schools of Hinduism and Buddhism).
