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 many of the adherents of traditional Sunni Islam (Sunni Sufis, for example) and Shia Islam, and in many parts of places like Turkey, Egypt, South Asia, and Southeast Asia. Other sects, such as Wahhabists etc., abhor the practice.
In Judaism, there is no classical or formal recognition of saints, but there is a long history of reverence shown toward biblical heroes and martyrs. In some regions, for example within Judaism in Morocco, there is a long and widespread tradition of saint veneration.
Both main branches of Buddhism, Theravada and Mahayana, recognize those who have achieved a high degree of enlightenment as an Arhat. Mahayana Buddhism particularly gives emphasis to the power of saints to aid ordinary people on the path to enlightenment. Those who have reached enlightenment, and have delayed their own complete enlightenment in order to help others, are called Bodhisattvas. Mahayana Buddhism has formal liturgical practices for venerating saints, along with very specific levels of sainthood. Tibetan Buddhists venerate especially holy lamas, such as the Dalai Lama, as saints.
