From a sociological perspective the denominations most likely to grow are those which are able to change in order to reach the younger generations and recent migrants. The aim of this paper is to explore how in the next twenty five years the Anglican Church of Australia can position itself to proclaim the Gospel to new generations of unreached Australians and migrants. A denomination can be described as a mainline church which has developed from either a Western national church or a broad Christian movement. It has an established organisation and tradition, and identifies with the worldwide body of professing Christians known as the Catholic Church. Denominations can be contrasted to Christian fellowships which usually stand apart from mainline denominations and their histories.
Denominations are also social entities with a membership that can be seen and numbered.
Membership in 'the Church Christ is building' is through spiritual birth and conversion. Denominations contain members of 'Christ's Church' but also nominal members. The Anglican Communion is a worldwide fellowship of independent national and regional churches that trace their origins back to the Church of England. The Anglican Church of Australia is a fellowship of twenty four independent dioceses, within the Anglican Communion. These dioceses are bound together by an agreed Constitution governing doctrine and practice.
