the local language, the structures of the Book of Common Prayer are largely retained. Churches which call themselves Anglican will have identified themselves so because they use some form or variant of the Book of Common Prayer in the shaping of their worship. Anglican worship, however, is as diverse as Anglican theology. A contemporary "low-church" service may differ little from the worship of many mainstream non-Anglican Protestant churches. The service is constructed around a sermon focused on Biblical exposition and opened with one or more Bible readings and closed by a series of prayers (both set and extemporised) and hymns or songs. A "high church" or Anglo-Catholic service, by contrast, is usually a more formal liturgy celebrated by clergy in distinctive vestments and may be almost indistinguishable from a Roman Catholic service, often resembling the "pre–Vatican II" Tridentine rite. Between these extremes are a variety of styles of worship, often involving a robed choir and the use of the organ to accompany the singing and to provide music before and after the service. Anglican churches tend to have pews or chairs, and it is usual for the congregation to kneel for some prayers but to stand for hymns and other parts of the service such as the Gloria, Collect, Gospel reading, Creed and either the Preface or all of the Eucharistic Prayer. Anglicans may genuflect or cross themselves in the same way as Roman Catholics. Other more traditional Anglicans tend to follow the 1662 Book of Common Prayer, and retain the use of the King James Bible. This is typical in many Anglican cathedrals and particularly in Royal Peculiars such as the Savoy Chapel and the Queen's Chapel. These services reflect older Anglican liturgies and differ from the Traditional Anglican Communion in that they are in favour of women priests and the ability of clergy to marry. These Anglican church services include classical music instead of songs, hymns from the New English Hymnal (usually excluding modern hymns such as "Lord of the Dance"), and are generally non-evangelical and formal in practice. Until the mid-20th century the main Sunday service was typically morning prayer, but the Eucharist has once again become the standard form of Sunday worship in many Anglican churches; this again is similar to Roman Catholic practice. Other common Sunday services include an early morning Eucharist without music, an abbreviated Eucharist following a service of morning prayer, and a
