This chapter discusses the development of Anglicanism through mission and argues that mission is essential to the church’s existence and flourishing. It proposes that the church’s mission has two aspects: the deepening and revitalization of the lives of those already within the Christian community, and the extension of the Gospel beyond the boundaries of that community. Among the key issues covered are the mission in the Reformation era, Evangelicals and abolition of slavery, mission under colonialism, as well as specific regions such as India, Rwanda, Burundi, Congo, Madagascar, Quebec and Haiti. The chapter then considers the modern mission by discussing the Nigerian experience, the struggle against apartheid, and the rebirth of Chinese Christianity. The last section allows the reader to consider the mission beyond Anglicanism.
