Veneration of the saints

Veneration (Latin veneratio or dulia, Greek , douleia), or veneration of saints, is the act of honoring a saint, a person who has been identified as having a high degree of sanctity or holiness.Angels are shown similar veneration in many religions. Philologically, "to venerate" derives from the Latin verb, venerare, meaning to regard with reverence and respect. Veneration of saints is practiced, formally or informally, by adherents of some branches of all major religions, including Christianity, Judaism, Hinduism, Islam, and Buddhism.

Within Christianity, veneration is practiced by groups such as the Eastern Orthodox Church, the Roman Catholic, and Eastern Catholic Churches, all of which have varying types of canonization or glorification procedures. In the Catholic and Orthodox Churches, veneration is shown outwardly by respectfully bowing or making the sign of the cross before a saint's icon, relics, or statue, or by going on pilgrimage to sites associated with saints. In general, veneration is not practiced by Protestants, with some denominations considering these practices heretical.

Hinduism has a long tradition of veneration of saints, expressed toward various gurus and teachers of sanctity, both living and dead. Branches of Buddhism include formal liturgical worship of saints, with Mahayana Buddhism classifying degrees of sainthood.

In Islam, veneration of saints is practiced by the adherents of Sunni Islam (for example Barelvism etc), Shia Islam and Sufism, and in many parts of Southeast Asia, along with "folk Islam", which often incorporates local beliefs and practices. Other sects, such as Wahhabists etc., abhor the practice.
