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.
Zealots
Josephus' "Jewish Antiquities" states that there were three main Jewish sects at this time, the Pharisees, the Sadducees, and the Essenes. The Zealots were a "fourth sect", founded by Judas of Galilee (also called Judas of Gamala) in the year 6 CE against Quirinius' tax reform, shortly after the Roman Empire declared what had most recently been the tetrarchy of Herod Archelaus to be a Roman province, and that they "agree in all other things with the Pharisaic notions; but they have an inviolable attachment to liberty, and say that God is to be their only Ruler and Lord." (18.1.6)
