At the 2007 General Synod, a resolution was passed which will begin the process of revising the modern language liturgies. Hymnody is an important aspect of worship in Anglicanism, and the ACC is no different. There is no one hymnal required to be used, although the ACC has produced four successive authorized versions since 1908. The most recent, Common Praise, was published in 1998. Anglican plainsong is represented in the new hymnal, as well as in the older Canadian Psalter, published in 1963. Notable Canadian Anglican hymnists include Derek Holman, Gordon Light, Herbert O'Driscoll, and Healey Willan. For a time, beginning in the early 1970s, many Anglican congregations experimented with The Hymn Book produced jointly with the United Church of Canada under the direction of Canadian composer F. R. C. Clarke, but both churches have since abandoned the common hymnal. Like most churches of the Anglican Communion, the ACC was beset by intense conflict over the ritualism controversies of the latter 19th century, leading in some extreme cases to schism. Throughout much of the 20th century, parishes – and, to a certain extent, dioceses or regions – were more or less divided between high church (Anglo-Catholic), low church (evangelical), and broad church (middle-of-the-road). Many of these designations have become muted with time, as the passions which fired the debate have cooled and most parishes have found a happy medium or accommodation. Social issues and theological division As is the case in churches directly influenced by Anglican ethos and theology, the ACC tends to reflect the dominant social and cultural strains of the nation in which it finds itself. For most of its history, the ACC embodied the conservative, colonial outlook of its mostly British-descended parishioners and of English Canada as a whole. In the post-World War II period, as the character of Canada changed, so too did the attitudes of people in the pews, and by extension, the church. Ordination of women and remarriage of divorced persons In recent years the ACC has been a leading progressive force within the Anglican Communion. In the 1970s the then primate, Ted Scott, argued at the Lambeth Conference in favour of women's ordination. The ACC ordained its first woman as a priest in 1976 and its first woman as a bishop in 1993. Many parishes, particularly in the west and even more particularly on aboriginal reserves, were already served by women deacons and
