"This is the gospel, that sins are remitted in the name of Christ; and no heart ever received tidings more glad." Huldrych Zwingli's contribution to the Reformation may have been just as important as Luther and Calvin's, yet many still don't know much about him, let alone read his powerful works. Zwingli preached against ecclesial corruption, fasting, the requirement of celibacy on the clergy, the veneration of saints, excommunication, and more—setting the stage for the Swiss Reformation. The Works of Zwingli (7 vols.) assembles some of Zwingli's most important works translated into English and includes historical works about his life and legacy.

While most Christians are familiar with the events and major participants of the Reformation, many still don't know very much about the Anabaptists—a sect of breakaway Christians who rejected the Roman Catholic Church and the idea of state churches altogether. Holding to principles of nonviolence, renunciation of the oath (based principally on Matthew 5:34–37 and James 5:12), and believer's baptism—the Anabaptists were persecuted for their beliefs by Catholics and Protestants. Among the various leaders of this pious group, Menno Simons became so influential, other Anabaptist leaders started referring to his Dutch followers as Mennonites.

Close friend of Martin Luther, important co-laborer in the Reformation, and talented scholar sometimes called “the teacher of Germany,” Philip Melanchthon occupies an essential place within the history of Protestantism. Church historian Philip Schaff once noted that “without Luther the Reformation would never have taken hold of the common people; without Melanchthon it would never have succeeded among the scholars of Germany.”
