One of the most pointed warnings Jesus uttered during His earthly ministry was: "Beware the leaven of the Pharisees and Sadducees...Leave them " He said this to His followers, without qualification. The apostle Paul worked to keep this leaven out of the fledgling churches as well. Why were they both so opposed to these men and what exactly were they warning their followers to avoid? This book takes an in-depth look at this subject, examining the wider implications of Jesus' words and then making the strongest possible case for their continued application to the Church today. This is a vitally important subject for every member of every church around the world, not just those in America. Indeed, the stakes could not be higher. We encourage every believer to read this book and devote themselves to understanding it. It will change your life (Keep in mind that, because this is such a difficult subject for so many in the institutional churches, negative and even hostile reviews should be viewed in that context.)
