A saint (from the Latinsanctus) in Christianity is a human being who has answered the call to holiness. The term is used differently by various denominations. In high-church contexts, such as Roman Catholicism or Anglo-Catholicism, a Saint is generally one to whom has been attributed (and who has generally demonstrated) a high level of holiness and sanctity. In this use, a saint is therefore not simply a believer, but one who has been unusually transformed. On the other hand, many denominations, notably in Protestantism, emphasise the traditional New Testament meaning of the word, preferring to write saint (lower case) to refer to any believer, in continuity with the doctrine of the priesthood of all believers. Several denominations venerate the dead saints, while others vehemently reject this. Some make a distinction between a "Romish" and a "Patristic" doctrine concerning the invocation of saints, permitting the latter.
The use of the term saint is not exclusive to Christianity. In most religious cultures, there are people who have been recognised within that culture as having fulfilled the highest aspirations of religious teaching. In English, the term saint is often used to translate this idea from many world religions.
Gregory made a significant impact on the shape of Trinitariantheology among both Greek- and Latin-speaking theologians, and he is remembered as the "Trinitarian Theologian". Much of his theological work continues to influence modern theologians, especially in regard to the relationship among the three Persons of the Trinity. Along with two brothers, Basil the Great and Gregory of Nyssa, he is known as one of the Cappadocian Fathers.
The Saints Wikiproject aims primarily at standardizing the articles about people venerated by some Christians as saints or the blessed and ensuring quality articles. If there is an interest in including saints from religions other than Christianity, please propose those changes on our talk page.
