Religious views on truth
There is no unilateral agreement among the different denominations of Judaism concerning truth. In Orthodox Judaism, truth is the revealed word of God, as found in the Hebrew Bible, and to a lesser extent, in the words of the sages of the Talmud. For Hasidic Jews truth is also found in the pronouncements of their rebbe, or spiritual leader, who is believed to possess divine inspiration. Kotzk, a Polish Hasidic sect, was known for their obsession with truth.
Messianic Judaism
Currently there are over 300 Messianic Jewish congregations in the United States with maybe half of their attendance being Gentiles. Most of these congregations belong to the International Association of Messianic Congregations and Synagogues (IAMCS), an arm of the Messianic Jewish Alliance of America (MJAA), or to the Union of Messianic Congregations (UMJC) or to Tikkun International.
