Yes, there are sects in Judaism. The three main sects in America are the Orthodox, the Conservative, and the Reform. There are blends and variations; and the old saying, "two Jews, three opinions" applies here.
Answer 2
All Jews have the same Torah.
Torah-observant Judaism dates back for a few thousand years. Originally it was simply called "Torah" or living by the Torah. Today it has the additional name of Orthodox Judaism.Orthodox Jews believe that the Torah must be fully observed (Deuteronomy 13:5). They keep the laws of Judaism as codified in the Shulchan Arukh (Code of Jewish Law), which lists the laws of the Torah and Talmud. Torah-study is seen as very important (Deuteronomy 5:1); and the modern world is seen as subservient to the Torah (Talmud, Nedarim 32a), not the other way around.
Other Jewish groups (Conservative, Reform) are recent. They adapt, curtail or change the Torah-laws in contemporary life, to a greater or lesser degree.
