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.
Jewish diaspora
Karaim are Jews who used to live mostly in Egypt, Iraq, and Crimea during the Middle Ages. They are distinguished by the form of Judaism which they observe. Rabbinic Jews of varying communities have affiliated with the Karaite community throughout the millennia. As such, Karaite Jews are less an ethnic division, than they are members of a particular branch of Judaism. Karaite Judaism recognizes the Tanakh as the single religious authority for the Jewish people. Linguistic principles and contextual exegesis are used in arriving at the correct meaning of the Torah. Karaite Jews strive to adhere to the plain or most obvious understanding of the text when interpreting the Tanakh. By contrast, Rabbinical Judaism regards an Oral Law (codified and recorded in the Mishnah and the Talmud) as being equally binding on Jews, and mandated by God. In Rabbinical Judaism, the Oral Law forms the basis of religion, morality, and Jewish life. Karaite Jews rely on the use of sound reasoning and the application of linguistic tools to determine the correct meaning of the Tanakh; while Rabbinical Judaism looks towards the Oral law codified in the Talmud, to provide the Jewish community with an accurate understanding of the Hebrew Scriptures.
