Church Multi-Level Marketing??

While Paul is one of my favorite New Testament writers, it troubles me the focus some are putting on his writings to the point that they say other NT writers weren't preaching the "Pure Gospel of Grace as Paul did" and therefore they invalidate other NT writings as acceptable and credible scripture.... Oh my, what a dangerous realm of error to be in, to become so full of pride that you think you have the authority to say what counts and doesn't count as scripture and that you have the right to throw out 1,2,&3 John, 1&2 Peter, James, Jude... because they weren't written by Paul?!?!?!? What errant thinking! ... I am bothered by how quickly, swiftly, and easily people are being caught up in this "new move", thinking it is the latest, greatest from God when really it is absolute error an unscriptural!!!! Anything that promises effortless living and abundant prosperity with no investment in other areas of Christian living(in accordance with the Bible) is nothing more than a multi-level marketing scheme within the church world!
