If you have ever wondered exactly how we got from the Christian society of the early centuries, united in its faithfulness to apostolic tradition, to the fragmented and secular state of the West today, The Age of Division will answer all your questions and more. In this second of a four-volume cultural history of Christendom, author John Strickland applies insights from the Orthodox Church to trace the decline and disintegration of both East and West after the momentous but often neglected Great Schism. For five centuries, a divided Christendom was led further and further from the culture of paradise that defined its first millennium, resulting in the Protestant Reformation and the secularization that defines our society today.

InThe Division of Christendom, revered historian Hans J. Hillerbrand details the events and ideas of the sixteenth century and contends that the Protestant Reformation must be seen as an interplay of religious, political, and economic forces in which religion played a major role. Hillerbrand tells the fascinating story of the ways in which theological disagreements divided the centuries-old Christian church and the roles that leading characters such as Luther, Zwingli, Anabaptists, and Calvin played in establishing new churches, even as Roman Catholicism continued to develop in its own ways. The book covers all significant aspects of this period and interprets these important events in their own context while reflecting on the consequences of the Reformation for later periods and for today.

Published to mark the 500th anniversary of the events of 1517, Reformation Divided explores the impact in England of the cataclysmic transformations of European Christianity in the sixteenth and seventeenth centuries. The religious revolution initiated by Martin Luther is usually referred to as 'The Reformation', a tendentious description implying that the shattering of the medieval religious foundations of Europe was a single process, in which a defective form of Christianity was replaced by one that was unequivocally benign, 'the midwife of the modern world'. The book challenges these assumptions by tracing the ways in which the project of reforming Christendom from within, initiated by Christian 'humanists' like Erasmus and Thomas More, broke apart into conflicting and often murderous energies and ideologies, dividing not only Catholic from Protestant, but creating deep internal rifts within all the churches which emerged from Europe's religious conflicts. The book is in three parts: In 'Thomas More and Heresy', Duffy examines how and why England's greatest humanist apparently abandoned the tolerant humanism of his youthful masterpiece Utopia, and became the bitterest opponent of the early Protestant movement. 'Counter-Reformation England' explores the ways in which post-Reformation English Catholics accommodated themselves to a complex new identity as persecuted religious dissidents within their own country, but in a European context, active participants in the global renewal of the Catholic Church. The book's final section 'The Godly and the Conversion of England' considers the ideals and difficulties of radical reformers attempting to transform the conventional Protestantism of post-Reformation England into something more ardent and committed. In addressing these subjects, Duffy shines new light on the fratricidal ideological conflicts which lasted for more than a century, and whose legacy continues to shape the modern world.
