modern state of Israel to Judaism.
While many Orthodox Jews accept the label "Orthodox", others reject and criticize it because it was never traditionally applied to Jews in ancient times or the Middle Ages. Many Orthodox Jews prefer to call their faith Torah Judaism. Unlike the modern denominations of Judaism, Orthodoxy is not a single movement or school of thought. There is no single group which all rabbis are expected to belong to. In the United States at the present time, there are a number of Orthodox congregational organizations, but none of them can claim to represent even a majority of all Orthodox congregations.
Orthodox Jews believe that God gave Moses the whole Torah (Written and Oral) at Mount Sinai.
Written Torah refers to the first five books of the Bible. Oral Torah interprets and explains the Written Torah. Orthodox Jews believe that the Torah contains 613 "mitzvot", or commandments, that are binding upon Jews. Orthodox Judaism is composed of different groups with intersecting beliefs, practices and theologies, and in their broad patterns, the Orthodox movements are very similar. Modern Orthodox Jews strictly observe "halakhah" Jewish Law, but still integrate into modern society. Ultra-Orthodox Jews, which includes Chasidic Jews, strictly observe Jewish laws and do not integrate into modern society by dressing distinctively and living separately. Most Orthodox groups characterize non-Orthodox forms of Judaism as heresy. Within orthodoxy, the various groups maintain significant social differences, and differences in understanding halakha due to their varying opinion concerning the role of women in Judaism, relations with non-Orthodox Jews, attitudes toward modern culture and modern scholarship, and how to relate to the State of Israel and
Zionism.
Orthodox Judaism affirms monotheism, the belief in one God. Orthodox Judaism maintains the traditional understanding of Jewish identity. A Jew is someone who was born to a Jewish mother, or who converts to Judaism in accordance with Jewish law and tradition. Orthodoxy does not allow intermarriage. Intermarriage is seen as a deliberate rejection of Judaism. An intermarried person is exiled from most of the Orthodox community.
