A fuzzy but important jubilee is slipping by without much notice in Anglicanism. For fifty years or thereabouts, a new liturgical paradigm has been at work, with a variety of intended and unintended consequences that go far beyond the resulting forms and words of common prayer. The year 1967 is hardly the only possible date on which to land for such an anniversary, which is more about a movement than a single event. The liturgical movement had already been in motion for decades; the Lambeth Conference of 1958 had set down principles for change in member Churches of the Communion. In 1967, however, the moves for change became public in ways that impacted the lives of many Anglicans beyond the realm of scholarly and episcopal debate. The 1967 General Convention of The Episcopal Church approved trial use for the experimental rites that would form the basis of the 1979 Prayer Book. 2 The Alternative Services Second Series ('Series II') of the Church of England appeared across 1966-67. Beyond Anglicanism, in October 1967 the complete draft of the new form of Mass for the Roman Catholic Church was presented to the Synod of Bishops, and celebrated for the first time in the Sistine Chapel. Ideas that had long flowed about in the quieter channels of expert and elite conversation now burst their banks, and have changed worship and Church ever since. 3
