Anglican=a member of the Church of England, or another church in the world-wide Anglican communion (formed by Anglican immigration and missionary activity), or a church influenced by the traditions of the Church of England. Sometimes used since the 19th century to describe an alleged “middle way” between “Roman” Catholicism and Protestantism, holding to the teachings of the “undivided” Church of the first millenium. But this is better described by the term “Anglo-Catholicism.”
TAC=an international communion of traditional Anglican churches. The U.S. branch, the “Anglican Church in America,” is one of a number of small denominations that broke away from the Episcopal Church owing to the ordination of women and the revision of the Prayer Book in 1979. These “Continuing Churches” differ very little from each other in doctrine but have been unable to form a united front so far.
Episcopal=the branches of the Anglican Communion existing in the Scotland, the United States, and a few other places (such as Mexico) whose Anglicanism derives from the U.S. Both Scotland and the U.S. originally used the term “Episcopal Church” to indicate that they were not simply puppets of England. Today, an Episcopalian in the U.S. is a member of the large, “mainline,” liberal expression of Anglicanism. Many conservative Episcopal parishes and dioceses (and individuals, such as myself) have begun referring to themselves as “Anglican” as a way of stressing our identification with the worldwide Communion, without actually leaving ECUSA.
Anglican Church of North America=the original name of the Continuing Anglicans. However, they very quickly split into several different groups, and I believe that the only part of ACNA left was the Province of Christ the King, so that it now refers to itself as the Anglican Church of the Province of Christ the King. GKC can perhaps correct me on this one.
ECUSA =the Episcopal Church in the U.S.A. The U.S. branch of the Anglican Communion, in full communion with Canterbury but currently in a state of impaired communion with a number of other parts of the Communion owing to the election of Gene Robinson.
Traditional Anglican Communion --see TAC
Church of England --the “mother church” of Anglicanism. The state church of England (not Scotland or Wales), with a wide variety of theological belief and practice ranging from low-church evangelicalism to Anglo-Catholicism to extreme liberalism.
Low Churchmen–the Protestant wing of Anglicanism, particularly with regard to ritual. At one time this meant something almost indistinguishable from Presbyterianism. Today that old-fashioned Low-Church Anglicanism still exists, but there are also charismatic Anglicans, and because of the shift toward Catholicism in the past couple of centuries “low church” may simply mean “not Anglo-Catholic”–no private confession, no incense or chanting, communion once a week with perhaps a mid-week Eucharist as well, etc. Today, any church not having weekly Eucharist is considered very low church indeed (whereas once monthly or quarterly communion was normal). Similarly, almost all Anglican priests (at least in the U.S.) wear Eucharistic vestments, which would have been almost unheard-of at one time.
High Churchmen=Anglicans who emphasize the importance of ritual, tradition, and the structure of the Church, and are more likely to emphasize the Fathers and the medieval tradition rather than the Reformation. The two typical high-church doctrines traditionally were baptismal regeneration and apostolic succession (though of course a stronger doctrine of the Eucharistic presence also came along with this). Since the 19th century “High Church” may be indistinguishable from “Anglo-Catholic,” but it may also be a bit broader.
