A patron saint, patroness saint, patron hallow or heavenly protector is a saint who in Catholicism, Anglicanism, or Eastern Orthodoxy is regarded as the heavenly advocate of a nation, place, craft, activity, class, clan, family, or person. The term may be applied to individuals to whom similar roles are ascribed in other religions. Saints often become the patrons of places where they were born or had been active. However, there were cases in Medieval Europe where a city which grew to prominence and obtained for its cathedral the remains or some relics of a famous saint who had lived and was buried elsewhere, thus making them the city's patron saint – such a practice conferred considerable prestige on the city concerned. In Latin America and the Philippines, Spanish and Portuguese explorers often named a location for the saint on whose feast or commemoration day they first visited the place, with that saint naturally becoming the area's patron. Occupations sometimes have a patron saint who had been connected somewhat with it, although some of the connections were tenuous. Lacking such a saint, an occupation would have a patron whose acts or miracles in some way recall the profession. For example, when the previously unknown occupation of photography appeared in the 19th century, Saint Veronica was made its patron, owing to how her veil miraculously received the imprint of Christ's face after she wiped off the blood and sweat. The veneration or "commemoration" and recognition of patron saints or saints in general is found in Catholicism (including Eastern Catholicism), Eastern Orthodoxy, Oriental Orthodoxy, and among some Lutherans and Anglicans. According to the Catholic catechism a person's patron saint, having already attained the beatific vision, is able to intercede with God for their needs. It is, however, generally discouraged in most Protestant branches such as Calvinism, where the practice is considered a form of idolatry. A canonized saint can be assigned as patron by a venerable tradition, or chosen by election.
