An excerpt from orthodox Jewish author Asher Norman’s must read book, “Twenty-Six Reasons Why Jews Don’t Believe in Jesus“:
The apostle Paul arrived on the Christian scene around 50 C.E., about 15 years after Jesus had been killed. Although Paul never met Jesus, he was the putative author of approximately half of the Epistles (letters) in the Christian Bible. In addition, Paul’s disciple Luke was the putative author of the books of Luke and Acts, which describe how Paul came to dominate the early Christian movement. Luke portrayed Paul as a fearless, virtually infallible central character in the Christian story…
Paul was a deeply troubled, wildly volatile personality. Significantly, Paul clearly revealed in his own Epistles that he was often accused of being a “liar”. The fact that the editors of the Christian Bible felt it necessary to reveal this embarrassing fact demonstrates that Paul’s credibility was a major issue. In addition, Paul stated in his Epistles that he believed that the ends justify the means. A strong case can be made that Paul lied about being born Jewish. This can be inferred from the fact that Paul used the word “we” when referring to Gentiles. There are significant indications that Paul was a failed convert to Judaism. Paul probably lied about being a member of the Pharisee party. This may be inferred from the fact that Paul worked as a policeman for the High Priest who was leader of the rival Sadducee party. Paul probably lied about being a student of Gamaliel, the leader of the Pharisee Party. This can be inferred from the fact that Gamaliel supported the law and opposed the High Priest while Paul opposed the law and worked for the High Priest. Logically, it is much more likely that Paul was a Sadducee, since he worked for the High Priest who was the leader of the Sadducee Party. Paul seemed to have a distorted sexual nature, which was expressed through his theology. Judaism views sexuality in the context of marriage as a holy creative act while Paul viewed sex within marriage as a concession to passion.
An early Christian group called the Ebionites was comprised of descendants of the original disciples. The Catholic Church persecuted the Ebionites out of existence by the fourth century, but fragments of their writings survive. They wrote that Paul was a Gentile who became a Jewish proselyte, was circumcised as a convert, and studied Judaism. They said that Paul arrived in Jerusalem from Tarsus as an adult hoping to marry the High Priest’s daughter. When she rejected him, Paul became enraged and wrote against circumcision, the kosher laws, the Sabbath, and finally opposed the efficacy of all the laws of the Torah.
