Since what Christian doctrine denies can be as important as what it affirms, it is important to understand teachings about Jesus that the early church rejected. Historians now acknowledge that proponents of alternative teachings were not so much malicious malcontents as they were misguided or even misunderstood. Here a recognized expert in early Christian theology teaches orthodox Christology by explaining the false starts (heresies), making the history of theology relevant for today's church. This engaging introduction to the christological heresies is suitable for beginning students. In addition, pastors and laypeople will find it useful for apologetic purposes.

There is a lot of talk about heresy these days. The frequency and volume of accusations suggest that some Christians have lost a sense of the gravity of the word. On the other hand, many believers have little to no familiarity with orthodox doctrine or the historic distortions of it. What’s needed is a strong dose of humility and restraint, and also a clear and informed definition of orthodoxy and heresy. Know the Heretics provides an accessible “travel guide” to the most significant heresies throughout Christian history. As a part of the KNOW series, it 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 unorthodox teaching, the orthodox response and a key defender; reflections of contemporary relevance; and discussion questions.

Beginning with Walter Bauer in 1934, the denial of clear orthodoxy in early Christianity has shaped and largely defined modern New Testament criticism, recently given new life through the work of spokesmen like Bart Ehrman. Spreading from academia into mainstream media, the suggestion that diversity of doctrine in the early church led to many competing orthodoxies is indicative of today's postmodern relativism. Authors Köstenberger and Kruger engage Ehrman and others in this polemic against a dogged adherence to popular ideals of diversity. Köstenberger and Kruger's accessible and careful scholarship not only counters the "Bauer Thesis" using its own terms, but also engages overlooked evidence from the New Testament. Their conclusions are drawn from analysis of the evidence of unity in the New Testament, the formation and closing of the canon, and the methodology and integrity of the recording and distribution of religious texts within the early church.

In Heresy, leading religion expert and church historian Alister McGrath reveals the surprising history of heresy and rival forms of Christianity, arguing that the church must continue to defend what is true about Jesus. He explains that remaining faithful to Jesus’s mission and message is still the mandate of the church despite increasingly popular cries that traditional dogma is outdated and restricts individual freedom.

Eighty years ago, Walter Bauer promulgated a bold and provocative thesis about early Christianity. He argued that many forms of Christianity started the race, but one competitor pushed aside the others, until this powerful 'orthodox' version won theday. The victors rewrote history, marginalizing all other perspectives and silencing their voices, even though the alternatives possessed equal right to the title of normative Christianity. Bauer's influence still casts a long shadow on early Christian scholarship. Were heretical movements the original forms of Christianity? Did the heretics outnumber the orthodox? Did orthodox heresiologists accurately portray their opponents? And more fundamentally, how can one make any objective distinction between 'heresy' and 'orthodoxy'? Is such labeling merely the product of socially situated power? Did numerous, valid forms of Christianity exist without any validating norms of Christianity? This collection of essays, each written by a relevant authority, tackles such questions with scholarly acumen and careful attention to historical, cultural-geographical, and socio-rhetorical detail. Although recognizing the importance of Bauer's critical insights, innovative methodologies, and fruitful suggestions, the contributors expose numerous claims of the Bauer thesis (in both original and recent manifestations) that fall short of the historical evidence.

In this volume, noted church historians Justo and Catherine Gonzalez introduce readers to important early church figures whose teachings were denounced by the church as heresies. Instructional for what they taught and for revealing what the church wished to safeguard and uphold, these "heretics" are engagingly presented in their contexts through clear and accessible text that is highlighted by the humorous illustrations of Ron Hill.

Traces the decline of Christianity in America since the 1950s, posing controversial arguments about the role of heresy in the nation's downfall while calling for a revival of traditional Christian practices.

From Bible teacher John MacArthur, a revelatory exploration of what the apostle Paul actually taught about the Good News of Jesus. The apostle Paul penned a number of very concise, focused passages in his letters to the early church that summarize the gospel message in just a few well-chosen words. Each of these key texts has a unique emphasis highlighting some essential aspect of the Good News of Jesus Christ. The chapters in this revelatory new book closely examine those vital gospel texts, one verse at a time. John MacArthur, host of the popular media ministry Grace to You, tackles such questions as: What is the gospel? What are the essential elements of the message? How can we be certain we have it right? And how should Christians be proclaiming the Good News to the world? As always, the answers John MacArthur gives are clear, compelling, well-reasoned, easy to grasp, and above all, thoroughly biblical. The Gospel According to Paul is written in a style that is easily accessible to lay people, including those who know very little about the Bible, while being of great value to seasoned pastors and experienced ministers. The Gospel According to Paul is the third in a series of books on the gospel by John MacArthur including – The Gospel According to Jesus and The Gospel According to the Apostles. The Gospel According to Paul is also available in Spanish, Evangelio según Pablo.

The book deals with thinkers and movements that were embraced by many second-century religious seekers but which are now largely forgotten or known only as "heretics": Basilides, Sethianism, Valentinus' school, Marcion, Tatian, Bardaisan, Montanists, Cerinthus, Ebionites, Nazarenes, Jewish-Christianity of the "Pseudo-Clementines," and Elchasites.
