Religion is the set of beliefs, feelings, dogmas and practices that define the relations between human being and sacred or divinity. A given religion is defined by specific elements of a community of believers: dogmas, sacred books, rites, worship, sacrament, moral prescription, interdicts, organization. The majority of religions have developed starting from a revelation based on the exemplary history of a nation, of a prophet or a wise man who taught an ideal of life.
A religion may be defined with its three great characteristics:
One generally distinguishes the religions called primitive or animists, the Oriental religions (Hinduism, Buddhism, Shintoism, Confucianism, Taoism...) and the religions monotheists derived from the Bible (Judaism, Christianity, Islam). Christianity has itself given birth to several religions or Christian Churches (Catholic, Orthodox, Protestant, Evangelic...)
The word religion is derived from Latin "religio" (what attaches or retains, moral bond, anxiety of self-consciousness, scruple) used by the Romans, before Jesus Christ, to indicate the worship of the demons.|
The origin of "religio" is debated since antiquity. Cicero said it comes from "relegere" (to read again, to re-examine carefully, to gather) in the meaning "to carefully consider the things related to the worship of gods".
