Throughout history, heresies have persisted, adapting to each new generation. Today, modern manifestations of these counterfeit teachings continue to infiltrate churches, threatening the very foundations of Christianity. So, how can church leaders and pastors effectively navigate these age-old controversies when they arise within their congregations? In his book, Roger Olson delves into the dual nature of heresies, revealing both the curses they bring and the unexpected gifts they offer the Church. While heresies can, on occasion, correct misguided interpretations of orthodoxy, they are far more sinister, intentionally distorting the faith and undermining the very essence of divine revelation. Olson expertly guides readers through the major heresies, detailing how the Church has historically responded to these threats, the key players involved, and the essential strategies pastors can employ to address these critical faith issues and educate their congregations about the true nature of Jesus, God, and salvation. To facilitate deeper exploration, the book includes thought-provoking questions for individual or group study. Additionally, a Leader's Guide with DVD and a Youth Study with DVD are available, featuring on-screen conversations between Adam Hamilton and Roger Olson, providing a comprehensive and engaging resource for church leaders and youth alike.
