This is a general term for a number of religious groups within the Christian church. Included are followers of Luther, Zwingli and Calvin of the Reformation. The term comes from the protesting minority in a German parliament at Spires in 1528AD during the Reformation. It has been expanded upon to include the Church of England, Anabaptists, Methodists and Presbyterians. There is some common ground on the role of The Bible in worship, the rejection of Papal authority, devotion to preaching and a reduction of Catholic religious styles of worship. However, there are also differences between the various groups.
