The Torah that G-d gave to Moses and the Jewish people at Sinai contained two parts:
The Written Torah (the Five Books of Moses), and the Oral Torah, which explains how the Written Torah is lived, understood, and applied.
From the days of Moshe Rabbeinu (Moses) until the time of Rabbeinu Hakadosh, the Oral Law was not written as a public text.
Instead, the leading authority of each generation, whether the head of the Sanhedrin (supreme court) or the prophet of that time, would receive the tradition from his teachers and transmit it orally to the people.
Individual scholars might keep private notes for themselves, recording what they had understood from their teachers’ explanations of the Torah and its laws.
These personal writings included:
1. Traditions received from earlier generations
2. And new legal rulings developed in each generation using the thirteen principles by which the Torah is interpreted
These rulings were brought before the Sanhedrin (supreme court), debated, and accepted when approved. This system remained in place from the time of Moshe until the era of Rabbeinu Hakadosh, around 150 years after the destruction of the Second Temple.
What Changed in the Time of Rabbeinu Hakadosh?
Rabbeinu Hakadosh saw that this system could no longer last. Students were becoming fewer. Suffering and instability were increasing.
The Roman Empire was expanding its rule and the Jewish people were becoming scattered across distant lands.
He feared that if the Oral Law remained only oral, it would be forgotten. So he gathered all the traditions, all the laws, and all the explanations that had been transmitted from Moshe Rabbeinu and from the courts of every generation after him. From this massive body of teaching, he composed the Mishnah.
He taught it publicly, until it became well known throughout Israel. The people then wrote it down and spread it everywhere. Rabbeinu Hakadosh and his court devoted their lives to teaching it, so that the Oral Torah would remain available to all and would never be lost.
Scripture itself gave permission for this step: “It is a time to act for G-d…” – Psalms 119:126.
A Teaching That Reveals the Depth of the Oral Torah
Based on a teaching of the Lubavitcher Rebbe:
When human beings repair relationships, when they choose honesty, responsibility, forgiveness, and care, they heal more than just each other.
They repair the relationship between creation and its Source, the Creator of the universe.
This repair work becomes an atonement on behalf of G-d for the suffering humanity experienced through creation.
This is one example of how the Oral Torah reveals the inner meaning of human action, responsibility, and relationship.
