Apostate Christianity is a term used to denote a religion that has turned away from doing the good works of Jesus Christ. In fact, Jesus Christ uses the term "Lukewarm" to describe the apostate works of Christianity. His remedy for the church to escape their apostate condition is to repent. The question for the church leaders then arises "What sin do we have to repent of? The answer to this question lies in the root cause of their apostasy which is that very doctrine they believe in for their salvation which produces these apostate works. Repenting of a doctrine one believes in for their salvation appears to be, in and of itself, apostasy. This makes it extremely difficult for the church to turn away from. However, if the church has faith to believe that this doctrine is false then they will be able to escape the deception contained in it for those that they can save through their repentance. This is the work of Christ. The founding doctrine of Christianity is faith in the work of Christ on the cross, in shedding his innocent blood, for their salvation. This book will prove, beyond a shadow of a doubt, that this doctrine of blood is that doctrine Christ calls on the church to repent of because it unjustly imputes the sin of his crucifixion upon sinners, in that their sins "nailed Christ to the cross". This is a concept that is not from Christ because he never taught it because he came to save sinners, not condemn their innocent blood for a work they had nothing to do with.
