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.
History of early Christianity
Judaism at this time was divided into antagonistic factions. The main camps were the Pharisees, Saducees, [Essenes] and Zealots. This led to further unrest, and the 1st century BC and 1st century AD saw a number of charismatic religious leaders, contributing to what would become the Mishnah of rabbinic Judaism, including Yohanan ben Zakkai and Hanina ben Dosa.
