The Smoking Gun:
The task of challenging the historicity of a "Torah Observant Rav Shaul (Paul)" is not very difficult, given that prior to the late 1980s there were only two opposed theological camps regarding Pauline teachings; Those that believed the Pauline gospels to be divinely inspired and those that considered Paul a heretic and his teachings opposed to early Church teachings (Neo-Ebionites). Within the Messianic Jewish Movement from the 1970s throughout most of the 1980s there was little discussion of Paul ever promoting Torah observance and some discussion regarding the Biblical authority of the Pauline gospels. By the mid 1990s though, the debate within the Messianic Jewish Movement by these two opposed camps apparently ended and a movement had begun to promote the acceptance of a Torah observant Paul and the reinterpretation of his Epistles . Why so? Did the TOMJ Neo-Ebionites discover a way of achieving their goals within the MJM without winning the theological debate? Apparently they did so! By adopting a Cultural Marxist historically deceptive strategy they hijacked the entire Messianic Jewish Movement without a fight. The beauty of all this deceit was that once the majority of believers within the movement accepted the historical fabrication, the originators never had to argue that Paul was a heretic again, since they invented a new Paul (Rav Shaul) that totally agreed with their goal of total Torah observance within the MJM.
The Evil Fruit of Deceit:
After the Pauline gospels vanished from the mindset of most Messianic Jews, the heresy then spread to the Hebrew Roots and Messianic Gentile movements that promoted this false gospel among thousands of Gentile Christians successfully. Today the Gentile Torah observant population predominates over the its smaller Messianic Jewish counterpart to the dismay of most Messianic Jewish and Christian leaders. The Messianic Jewish leaders that originated the heresy though have washed their hands of any guilt for promoting these historical distortions. Many Messianic Jewish rabbis and their dedicated followers still cling to the Torah observant Rav Shaul fabrications and refuse to consider them as historical distortions. To compound the problem, the grace oriented Messianic Jewish or Hebrew Christian ministries mostly address the problem as "their problem". This apathy alludes to one of the reasons why they were so easily defeated decades ago. Also, in the last decade many historical errors have filtered down to these ministries as well.
Below, you will find a factual video explaining how Cultural Marxism began and how it has permeated all of Western culture. Other articles also explain the fight that Christians must wage to combat these false spirits. The Messianic Literary Corner also has numerous articles and reference links below explaining the principles of grace and the necessity to submit all Torah observances to these principles.
