Looking this up I came across this:
According to a Jewish tradition[13], the Rabbis were very scared of early Christianity and knew that the religion would go on to become successful. In order to save future Jews from both death and definite assimilation, the Rabbis of the time sent a man to infiltrate the Christian communities and change the Christian doctrine to become so distinct from Judaism that it is proselytizing will focus on gentiles and not Jews. He was also to change the Christian doctrine to become favorable to Jews, even outlawing the murder of Jews. This man was named Saul, who later became known as Paul. Paul, who may or may not have been a student of Rabban Gamliel,[14] helped shape the Pauline doctrine that forbade Christians from killing Jews[15] and switched the Christian day of rest from Saturday to Sunday to alienate more Jews as a way of maintaining Judaism without having more Jews succumb to the Christian religion[16]. The first pope, Peter Kephas, is known as Shimon Keifa in Jewish tradition, and he was the author of the liturgical poem Nishmas Kol Chai[17]. Rabbi Yehuda HaChassid of Regensburg (1150-1217) even called[18] Peter a righteous man who had good intentions in his seeming apostasy. Others explain that he was not a secret agent of the Pharisee Rabbis in an attempt to undermine Christianity, but rather he was a total apostate and only repented on his deathbed whereupon he wrote Nishmas.
It was highly appropriate that in 2006 the National Geographic published its findings regarding the Gospel of Judas around the time of the year that NBC plays The Ten Commandments, that is, the Easter and Passover season. The Gospel of Judas (carbon-dated to circa. 200-300 A.D.) tells a story in which Judas Iscariot did not betray his supposed teacher, Jesus, but rather handed him over to the Roman authorities because his teacher told him to do so. All the anti-Semitism that the Passion play stories, especially around the Easter and Passover season, have caused throughout history were by insinuating that all Jews are betrayers of Jesus like Judas was. However, this logic does not really follow because many of Jesus’ students were Jewish, so if one betrays him that should not necessarily brand all Jews greedy, avaricious, mosers. When the French bishop Irenaeus (ca. 130-202 CE) banned the Gospel of Judas, he purposefully wanted the church to become anti-Jewish. If the Christians were only exposed to the Gospels of Mark, Matthew, Luke, and John they would get a bad picture of Judas and effectively apply that to all Jews. Even if this was not his intent, he at least, wanted to distinguish Christianity from Judaism for whatever reasons[11] by demonizing the Jew. The Gospel of Judas will never be given the same credit as the other gospels within the Christian communities because it would take away their justification for many acts of anti-Semitism they committed throughout history.
