Book excerpt: Progressive Christianity is an ethos, a mind set, more than a movement. It is indebted to political progressivism and postmodern philosophy. It has a trajectory, which is secularism. In Deconstructing Progressive Christianity John Piippo explains this ethos, with its corresponding trajectory. He explains the differences between historic Christianity and progressive Christianity, and finds the latter to be a different kind of religion. In the process of deconstruction we see key missing elements, such as atonement theory, the resurrection of Christ, and non-natural realities. The idea of moral and spiritual human progress is seen as a myth, and progressive beliefs about love are examined. In this book you will come to better understand the progressive ethos as it relates to religion, and why progressive Christianity is best understood as distant from historic Christianity.
