The 3 star rating is not an endorsement of the contents of the book, but to note that I found the book to be interesting in subject matter and writing style.
The main things I'll point out is that like J. Gresham Machen in "Christianity and LIberalism', Edman also concludes that between "progressive christianity" and "evangelical christianity" there are essentially two different religions. She just comes to a different conclusion on which is "authentic". Machen's point about the danger of liberalism was that it made use of historically Christian terms, but at it's core was a substitute dangerous to the soul. The author makes use of much scripture in order to aid in the storytelling, but from the standpoint of authority, looks to her own and our own experience as equal to and above the writings of scripture. There is also, a heavy emphasis and attempt to note the positives of the carnal. This is incompatible with the spiritual, carnality is death to the spiritual:
Romans 8:6 "For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace."
There is a very important distinction to be made when considering the idea of "the flesh". We are not to despise it in the sense that God created the body to be immortal, and so we have an expectation of resurrection. The danger of the flesh, is the lust of the flesh.
There is also a reiteration of a creative interpretation of "the law" as being the roman law. This completely misses the simplest reading of the entire Bible. The law is the mosaic / moral law, that all of us fail to adhere to, putting us all under the condemnation of God. The question that biblical, true, historical, and orthodox Christianity answers is how we escape the just wrath of God. The answer is faith in Jesus, repentance unto life, a life lived loving God with all our hearts, and our neighbors as ourselves.
