Judaism
There are some movements that combine elements of Judaism with those of other religions. The most well-known of these is Messianic Judaism, a religious movement, which arose in the 1960s, that incorporates elements of Judaism with the tenets of Christianity. The movement generally states that Jesus is the Jewish Messiah, that he is one of the Three Divine Persons, and that salvation is only achieved through acceptance of Jesus as one's savior. Some members of the movement argue that Messianic Judaism is a sect of Judaism. Jewish organizations of every denomination reject this, stating that Messianic Judaism is a Christian sect, because it teaches creeds which are identical to those of Pauline Christianity.
Origins of Rabbinic Judaism
Judaism at this time was divided into antagonistic factions. The main camps were the Pharisees, Saducees, and Zealots, but also included other less influential sects. This led to further unrest, and the 1st century BC and 1st century AD saw a number of charismatic religious leaders, contributing to what would become the Mishnah of Rabbinic Judaism, including Yochanan ben Zakai and Hanina Ben Dosa. The ministry of Jesus, according to the account of the Gospels, falls into this pattern of sectarian "preachers" or "teachers" with devoted "disciples" (derived from the Greek word for "students").
