Evolution of Halacha
Where did it all begin?
Nevi'im: Nevi’im (Prophets) presents Israel's History as a nation on its land.It is dived into two major parts: four books of the "Former" prophets and 14 books of the "Latter" prophets.
Ketuvim: Ketuvim, the name of the third section of the Tanach ,means "Writings",Most of the individual books in Ketuvim were written or at least put in final form in Judea during the period of Persian and Hellenistic rule, from the fifth through the second centuries BCE.
Gemara: Three centuries following the compilation of the Mishnah, rabbis throughout Eretz Yisrael and Balbylonia analysed, debated and discussd that work, these were all recorded in the Gemara
Commentators: Commentaries are there to help us understand the Torah and Talmud and contribute to the study and teaching of earlier texts. Several commentators such as Rashi, Rambam and Tosafot are still well known today because of their contributions and explanations.
Codes: The large amount of information written on Jewish law brought about the need to codify the material, separating the Halachic decisions from discussions and arguments and record the Halachic decisions. The most famous codes of Jewish law are Shulchan Aruch which was composed by Rabbi Yosef Karo in the 1560's as well as the Mishneh Torah which was composed by Rambam.
Responsa: Responsa are the answers given by authorities in Jewish law to questions put to them. Collections were made of the Geonic Responsa, especially those of Sherira Gaon and his son Hai Gaon, but while these collections were known to the medieval authorities they did not appear in print until as late as the nineteenth century.
