This book seeks to clarify and demonstrate the incalculable and injurious influence that progressive education has had and is having upon preaching, thinking Christianly, and the local church. Progressive education began at the turn of the twentieth century, replacing classical education with what is purportedly a science-based education, which necessarily results in scientism. This seismic shift in public education has not only affected what we learn but how we think. In order to enable the church to detect progressivism's deleterious sway and protect herself by being equipped with the progressive revelation of God, and thereby counter the influence of progressive education of man, I seek to highlight some of the underlying intolerable essentials of progressive education. In the companion book to this one, The Equipping Church: Somewhere Between Fundamentalism and Fluff, I explain the biblical model for the local church and how to build such a church.
