This Companion brings together new contributions from internationally renowned scholars in order to examine the past, present and future of Protestantism. The volume opens with an investigation into the formation of Protestant identity, looking at its historical development across Europe, North America, Asia, Australasia and Africa. This section includes coverage of leading Protestant thinkers, such as Luther, Calvin, Schleiermacher and Barth. The Companion then goes on to consider the interaction of Protestantism with different areas of modern life, including the arts, politics, the law and science. A final section looks to the future of Protestantism, debating what will happen to both Western and non-Western Protestant movements. The Companion takes seriously the shift in Protestantism from a predominantly North Atlantic perspective to a more global reality. A strength of the volume is contributions by indigenous scholars on regional Protestant history and context as well as essays that examine the nature of neo-Protestant forms and the future of historic Protestantism identities as a consequence of increasing secularity and the emergence of 'new' non-Eurocentric or American Protestants.
