Sup lad, I'm actually a theologian.
Jewish Torah is the same as the Old Testament
I said the Talmud. The Talmud is what Jews used to interpret the Torah.
YFW you realize that Jesus wasn't a Judean
Jesus was of the house of David, this is one of the prophecies and it is recorded in his genealogies. David is of the tribe of Judah.
The Genealogy of Jesus the Messiah
This is the genealogy of Jesus the Messiah the son of David, the son of Abraham:
Abraham was the father of Isaac,
Isaac the father of Jacob,
Jacob the father of Judah and his brothers,
Judah the father of…
The above is Jesus' genealogy in the Bible. Jesus is of the tribe of Judah.
Pharisees were just the pro Roman Jews
Pharisees followed the 'Oral Torah', which supposedly was about in the time of Moses (it is not the Torah written by Moses).
According to Rabbinic Judaism, the Oral Torah or Oral Law (Hebrew: תורה שבעל פה, Torah she-be-`al peh, lit "Torah that is spoken") represents those laws, statutes, and legal interpretations that were not recorded in the Five Books of Moses, the "Written Torah" (Hebrew: תורה שבכתב, Torah she-bi-khtav, lit. "Torah that is written"), but nonetheless are regarded by Orthodox Jews as prescriptive and co-given. This holistic Jewish code of conduct encompass a wide swath of ritual, worship, God-man and interpersonal relationships, from dietary laws to Sabbath and festival observance to marital relations, agricultural practices, and civil claims and damages.
According to Jewish tradition, the Oral Torah was passed down orally in an unbroken chain from generation to generation until its contents were finally committed to writing following the destruction of the Second Temple in 70 CE, when Jewish civilization was faced with an existential threat.
The major repositories of the Oral Torah are the Mishnah, compiled between 200–220 CE by Rabbi Yehudah haNasi, and the Gemara, a series of running commentaries and debates concerning the Mishnah, which together are the Talmud, the preeminent text of Rabbinic Judaism. In fact, two "versions" of the Talmud exist: one produced in Jerusalem c. 300–350 CE (the Jerusalem Talmud), and second, more extensive Talmud compiled in Babylonia and published c. 450–500 CE (the Babylonian Talmud).
The Pharisees /ˈfærəˌsiːz/ were at various times a political party, a social movement, and a school of thought in the Holy Land during the time of Second Temple Judaism. After the destruction of the Second Temple in 70 CE, Pharisaic beliefs became the foundational, liturgical and ritualistic basis for Rabbinic Judaism.
Conflicts between Pharisees and Sadducees took place in the context of much broader and longstanding social and religious conflicts among Jews, made worse by the Roman conquest. Another conflict was cultural, between those who favored Hellenization (the Sadducees) and those who resisted it (the Pharisees). A third was juridico-religious, between those who emphasized the importance of the Second Temple with its rites and services, and those who emphasized the importance of other Mosaic Laws. A fourth point of conflict, specifically religious, involved different interpretations of the Torah and how to apply it to current Jewish life, with Sadducees recognizing only the Written Torah (with Greek philosophy) and rejecting doctrines such as the Oral Torah, the Prophets, the Writings, and the resurrection of the dead.
Christians by the way do NOT follow the 'Oral Torah', and it is in fact what Jesus is condemning the Pharisees for at several points.
