The Fifth-Century Political Battles That Forever Changed the Church In this fascinating account of the surprisingly violent fifth-century church, PhilipJenkins describes how political maneuvers by a handful of powerful charactersshaped Christian doctrine. Were it not for these battles, today’s church could beteaching something very different about the nature of Jesus, and the papacy as weknow it would never have come into existence. Jesus Wars reveals the profoundimplications of what amounts to an accident of history: that one faction ofRoman emperors and militia-wielding bishops defeated another.

In this new edition of a classic work, the great Catholic apologist and historian Hilaire Belloc examines the five most destructive heretical movements in Christianity: Arianism, Mohammedanism (Islam), Albigensianism, Protestantism, and Modernism. Belloc describes how these movements began, how they spread, and how they have continued to influence the world. He accurately predicts the re-emergence of militant Islam and its violent aggression against Western civilization. When we hear the word "heresies", we tend to think of distant centuries filled with religious quarrels that seemed important at the time but are no longer relevant. Belloc shows that the heresies of olden times are still with us, sometimes under different names and guises, and that they still shape our world.

One of America's foremost scholars of religion examines the tumultuous era that gave birth to the modern Judeo-Christian tradition In The Crucible of Faith, Philip Jenkins argues that much of the Judeo-Christian tradition we know today was born between 250-50 BCE, during a turbulent "Crucible Era." It was during these years that Judaism grappled with Hellenizing forces and produced new religious ideas that reflected and responded to their changing world. By the time of the fall of the Temple in 70 CE, concepts that might once have seemed bizarre became normalized-and thus passed on to Christianity and later Islam. Drawing widely on contemporary sources from outside the canonical Old and New Testaments, Jenkins reveals an era of political violence and social upheaval that ultimately gave birth to entirely new ideas about religion, the afterlife, Creation and the Fall, and the nature of God and Satan.

In every generation, the Christian church must interpret and restate its bedrock beliefs, answering the challenges and concerns of the day. This accessible overview walks readers through centuries of creeds, councils, catechisms, and confessions—not with a dry focus on dates and places, but with an emphasis on the living tradition of Christian belief and why it matters for our lives today. As a part of the KNOW series, Know the Creeds and Councils is designed for personal study or classroom use, but also for small groups and Sunday schools wanting to more deeply understand the foundations of the faith. Each chapter covers a key statement of faith and includes a discussion of its historical context, a simple explanation of the statement’s content and key points, reflections on contemporary and ongoing relevance, and discussion questions.

This unique work - no other work yet available in English treats this subject - illustrates the contribution of these Councils in the development and formulation of Christian beliefs. It then shows how their legacies lingered throughout the centuries to inspire - or haunt - every generation.

There have been twenty-one universal gatherings 'ecumenical councils' of the Catholic Church. The first opened in 325, the last closed in 1965, and the names of many ring out in the history of the church: Nicea, Chalcedon, Trent, Vatican II. Though centuries separate the councils, each occurred when the church faced serious crises, sometimes with doctrinal matters, sometimes with moral or even political matters, and sometimes with discerning the church's relation to the world. The councils determined much of what the Catholic Church is and believes. Additionally, many councils impacted believers in other Christian traditions and even in other faiths. In this accessible, readable, and yet substantial account of the councils Joseph Kelly provides both the historical context for each council as well as an account of its proceedings. Readers will discover how the councils shaped the debate for the following decades and even centuries, and will appreciate the occasional portraits of important conciliar figures from Emperor Constantine to Pope John XXIII.
