A. Rabbi Judah the Prince or as he was called: Rebbe (teacher). He compiled the Mishna circa 218 C.E. He was the first to officially commit to writing the teachings of the Oral Law which was passed down, studied, discussed and observed in an uninterrupted chain from Sinai till his (our) day. The Mishna is divided into 6 main “orders” which comprise in very terse, skeletal form all of Jewish Law. The Mishna provides the basis for the Talmud which expounds on the Mishna’s teachings, in much greater depth,with immense detail and very lengthy discussion.
