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.
Historical background of the New Testament
Historians seek to understand where Jesus and his followers fit among other Jewish factions at the time. According to the Jewish-Roman historian Flavius Josephus, the three parties in contemporary Judaism were the Pharisees, the Sadducees and the Essenes, the last of these three being apparently marginalized and in some cases retired to quasi-monastic communities. Josephus also speaks of a "Fourth Movement", "Zealots", "Lestai" or "Sicarii".
The Pharisees were a powerful force in 1st-century Judea. Early Christians shared several beliefs of the Pharisees, such as resurrection, retribution in the next world, angels, human freedom, and Divine Providence. After the fall of the Temple, the Pharisaic outlook was established in Rabbinic Judaism. Some scholars speculate that Jesus was himself a Pharisee. In Jesus' day, the two main schools of thought among the Pharisees were the House of Hillel, which had been founded by the eminent Tanna, Hillel the Elder, and the House of Shammai. Jesus' assertion of hypocrisy may have been directed against the stricter members of the House of Shammai, although he agreed with their teachings on divorce. Jesus also commented on the House of Hillel's teachings (Babylonian Talmud, Shabbat 31a) concerning the greatest commandment and the Golden Rule. Historians do not know whether there were Pharisees in Galilee during Jesus' life, or what they would have been like.
