This 212-page book documents over 15 serious unBiblical heresies taught by key Gnostic leaders from all over the world. It will be seen from this study that the modern Bible versions like the ASV, ERV, RSV, NRSV, NEB, NASV, NIV, ESV, and many others, contain many of these same doctrinal heresies. These heresies are not by accident. They were purposely caused. The reason for this is that the headquarters of Gnosticism was Alexandria, Egypt. It is also true that the Vatican and Sinai N.T. Greek manuscripts, on which these new versions are based, originated in this same city-Alexandria, Egypt. It is clear that, when the Traditional Greek Words in the Gnostics’ possession opposed their heresies, these apostate Gnostics doctored the N.T. Greek Words in order to conform them to these heresies. In actuality, Gnosticism-not some manuscript debate-is the doctrinal foundation of the Vatican and Sinai Greek N.T. manuscripts and hence the doctrinal foundation of the new Bible versions which are based upon them. This explains the title of this book: GNOSTICISM-The Doctrinal Foundation Of the New Bible Versions.
