In various religions, saints are important people who are believed to have exceptional holiness. In orthodox and catholic teachings, all Christians in heaven are considered to be saints, but some are considered to be worthy of higher honor, emulation, or veneration In the Anglican Communion and the Continuing Anglican movement, the title of Saint refers to a person who has been elevated by popular opinion as a pious and holy person. The saints are seen as models of holiness to be imitated, and as a 'cloud of witnesses' that strengthen and encourage the believer during his or her spiritual journey (Hebrews 12:1). The saints are seen as elder brothers and sisters in Christ. Official Anglican creeds recognise the existence of the saints in heaven. So far as invocation of the saints is concerned, one of the Church of England's Articles of Religion "Of Purgatory" condemns "the Romish Doctrine concerning...(the) Invocation of Saints" as "a fond thing vainly invented, and grounded upon no warranty of Scripture, but rather repugnant to the Word of God". However, each of the 44 member churches in the Anglican Communion are free to adopt and authorise their own official documents, and the Articles are not officially normative in all of them Anglo-Catholics in Anglican provinces using the Articles often make a distinction between a "Romish" and a "Patristic" doctrine concerning the invocation of saints, permitting the latter. In high-church contexts, such as 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 a believer, but one who has been transformed by virtue. In Roman Catholicism, a saint is a special sign of God's activity. Anglicans believe that the only effective Mediator between the believer and God the Father, in terms of redemption and salvation, is God the Son, Jesus Christ.
