many of the high church clergy led to the designation ritualist being applied to them in a somewhat contemptuous sense. However, the terms high churchman and ritualist have often been wrongly treated as interchangeable. The high churchman of the Catholic type is further differentiated from the earlier use of what is sometimes described as the "high and dry type" of the period before the Oxford Movement. Modern use In contemporary usage, "low churches" place more emphasis on the Protestant nature of Anglicanism than broad or high churches and are usually Evangelical in their belief and conservative (although not necessarily traditional) in practice. They may tend to favour liturgy such as the Common Worship over Book of Common Prayer, services of Morning and Evening Prayer over the Eucharist, and many use the minimum of formal liturgy permitted by church law. The Diocese of Sydney has largely abandoned the Prayer Book and uses free-form evangelical services. Some contemporary low churches also incorporate elements of charismatic Christianity. More traditional low church Anglicans, under the influence of Calvinist or Reformed thought inherited from the Reformation era, reject the doctrine that the sacraments confer grace ex opere operato (e.g., baptismal regeneration) and lay stress on the Bible as the ultimate source of authority in matters of faith necessary for salvation. They are, in general, prepared to cooperate with other Protestants on nearly equal terms. Some low church Anglicans of the Reformed party consider themselves the only faithful adherents of historic Anglicanism and emphasise the Thirty-Nine Articles of the Church of England as an official doctrinal statement of the Anglican tradition. Ecumenical relationships United churches with Protestants in Asia Several provinces of the Anglican Communion in Asia have merged with Protestant churches. The Church of South India arose out of a merger of the southern province of the Church of India, Pakistan, Burma and Ceylon (Anglican), the Methodist Church of South India and the South India United Church (a Congregationalist, Reformed and Presbyterian united church) in 1947. In the 1990s a small number of Baptist and Pentecostal churches joined also the union. In 1970 the Church of India, Pakistan, Burma and Ceylon, the United Church of North India, the Baptist Churches of Northern India, the Church of the Brethren in India, the Methodist Church (British and Australia Conferences) and the Disciples of Christ denominations merged to form the Church of North India. Also in 1970 the
