Religious texts, including scripture, are texts which various religions consider to be of central importance to their religious tradition. They differ from literature by being a compilation or discussion of beliefs, mythologies, ritual practices, commandments or laws, ethical conduct, spiritual aspirations, and for creating or fostering a religious community. The relative authority of religious texts develops over time and is derived from the ratification, enforcement, and its use across generations. Some religious texts are accepted or categorized as canonical, some non-canonical, and others extracanonical, semi-canonical, deutero-canonical, pre-canonical or post-canonical.
