 As a consequence of these developments, different theological streams have emerged which today exist alongside the mainstream of the Church.While Adventism is a child of the 16th century Reformation initiated by Martin Luther, John Calvin and Ulrich Zwingli, its theological orientation really finds itself at home with the Radical Reformation or the Anabaptists.Anabaptists went back to the original early church teachings and rejected infant baptism and state support of the church.
