The terms Anglo-Catholicism, Anglican Catholicism and Catholic Anglicanism refer to people, beliefs and practices within Anglicanism that emphasise the Catholic heritage and identity of the various Anglican churches.
The term "Anglo-Catholic" was coined in the early 19th century, although movements emphasising the Catholic nature of Anglicanism had already existed. Particularly influential in the history of Anglo-Catholicism were the Caroline Divines of the seventeenth century and later the leaders of the Oxford Movement, which began at the University of Oxford in 1833 and ushered in a period of Anglican history known as the "Catholic Revival".
A minority of Anglo-Catholics, sometimes called Anglican Papalists, consider themselves under papal supremacy even though they are not in communion with the Roman Catholic Church. Such Anglo-Catholics, especially in England, often celebrate Mass according to the contemporary Roman Catholic rite and are concerned with seeking reunion with the Roman Catholic Church.
In addition, members of the personal ordinariates for former Anglicans created by Pope Benedict XVI are sometimes unofficially referred to as "Anglican Catholics".
Following the passing of the Act of Supremacy and Henry VIII's break with the Catholic Church, the Church of England continued to adhere to traditional Catholic teachings and did not initially make any alterations to doctrine. The Ten Articles were published in 1536 and constitute the first official Anglican articles of faith. The articles for the most part concurred with the teachings of the Church in England as they had been prior to the Protestant Reformation and defended, among other things, the Real Presence of Christ in the Eucharist, the sacrament of Confession, the honouring and invocation of Christian saints and prayer for the dead. Belief in purgatory, however, was made non-essential. This was followed by the The Institution of the Christian Man (also called The Bishops' Book) in 1537, a combined effort by numerous clergy and theologians which—though not strongly Protestant in its inclinations—showed a slight move towards Reformed positions. The Bishops' Book was unpopular with conservative sections of the Church, and quickly grew to be disliked by Henry VIII as well. The Six Articles, released two years later, moved away from all Reformed ideas and strongly affirmed Catholic positions regarding matters such as transubstantiation and Mass for the dead. The King's Book, the official article of religion written by Henry in 1543, likewise expressed Catholic sacramental theology and encouraged prayer for the dead.
