Jewish beliefs, law and tradition are based on the Torah, which is also known as the Five Books of Moses. The Torah contains 613 commandments according to the rabbinic tradition. The laws are divided for men, women, priestly groups, and even farmers. While the Torah has been the main written text for Jews, most Jewish people believe in the Oral Law, which have been documented and further taught by rabbis. The Torah, or the written law, cannot be studied without the reader being familiar with the oral law. The Jewish way of life is called Halakha and is based on the unity of oral and written tradition.
Jewish people have a covenant relationship with God, through which they must obey the laws set by God in order to receive the support and good deeds of God. Therefore, Judaism is considered a faith of action. Jews aim to follow the law as well as the spirit of the law. Therefore, they instill holiness to daily occurrences. Jews believe that that Jesus is a teacher and that followers of Christianity split from Judaism in order to revere Jesus as a Messiah.
Since the sixth century CE, Rabbinic Judaism has been the main form of Judaism and is based on the belief that the written law, the Torah, goes hand in hand with references to the oral Torah, which also determines what behavior is permitted according to the law, or "the way."
To be considered a Jewish person, one must be the child of a Jewish mother. Some Jewish groups accept children of Jewish fathers as Jews, as well. Converting to Judaism, however, is complicated.
