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.
Sadducees
The Sadducees (; Hebrew: "Ṣĕdûqîm") were a sect or group of Jews that was active in Judea during the Second Temple period, starting from the second century BCE through the destruction of the Temple in 70 CE. The sect was identified by Josephus with the upper social and economic echelon of Judean society. As a whole, the sect fulfilled various political, social, and religious roles, including maintaining the Temple. The Sadducees are often compared to other contemporaneous sects, including the Pharisees and the Essenes. Their sect is believed to have become extinct some time after the destruction of Herod's Temple in Jerusalem in 70 CE, but it has been speculated that the later Karaites may have had some roots in—or connections with—Sadducaic views.
