Article X of the Canons of the Episcopal Church provides that "he Book of Common Prayer, as now established or hereafter amended by the authority of this Church, shall be in use in all the Dioceses of this Church," which, of course, is a reference to the 1979 Book of Common Prayer. Many traditionalists, both Anglo-Catholics and Evangelicals, felt alienated by the theological and ritual changes made in the 1979 BCP, and resisted or looked elsewhere for models of liturgy. In 1991 the Anglo-Catholic Church of the Good Shepherd (Rosemont, Pennsylvania) published a book entitled, the "Anglican Service Book" which is "a traditional language adaptation of the 1979 Book of Common Prayer together with the Psalter or Psalms of David and Additional Devotions." In 2000, the General Convention of the Episcopal Church issued an apology to those "offended or alienated during the time of liturgical transition to the 1979 Book of Common Prayer."
