In Christian belief, a saint, also known as a hallow, is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term saint depends on the context and denomination. Official ecclesiastical recognition, and veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. The saints are honored in the liturgical calendars of Evangelical Lutheranism and Anglicanism. In other nonconformist denominations, such as the Plymouth Brethren, and following from Pauline usage, saint refers broadly to any holy Christian without special recognition or selection.
While the English word saint (deriving from the Latin sanctus) originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special holiness that many religions attribute to certain people", referring to the Hindu rishi, Sikh bhagat or guru, the Shintoist kami, the Taoist immortal or zhenren, the Jewish tzadik, the Islamic walī/fakir, and the Buddhist arhat or bodhisattva also as saints. Depending on the religion, saints are recognized either by official declaration, as in Roman Catholicism, Oriental Orthodoxy or Eastern Orthodoxy, or by popular acclamation (see folk saint).
