What Makes You Jewish On Shavuot

Rabbi Yaron Reuven discusses what it means to be Jewish on Shavuot, emphasizing that true Judaism is defined by a complete acceptance of the Torah rather than just lineage. Rabbi Reuven uses the historical context of the Torah being given to explain the boundaries between Jews and non-Jews, as well as the rules regarding conversion and Torah study.

While having a Jewish mother qualifies someone to be a Jew by default, true Jewish identity requires actively accepting the Torah. A Jewish person who abandons the laws and does not keep Shabbat is considered an idol worshiper, as there is no concept of a "good" or "bad" Jew. Before the Torah was given, Judaism didn't exist, and all people were considered Noahides. The Avot kept many laws before the Torah was given, but they deliberately violated Shabbat because they were not permitted to observe it.

Living a "half-Jewish" life by keeping select holidays and laws without officially converting is strictly forbidden, and Rambam says this creating a completely new religion. Non-Jews are permitted to learn the basics of the written Torah: the Five Books of Moses, Prophets and the Writings, and Mussar. Non-Jews are forbidden from learning mystical aspects like Kabbalah or the intricate details of the mitzvot , and doing so is considered theft that carries heavenly consequences. Parashat Yitro serves as a reminder that anyone can become a Jew , which is ultimately achieved by fully accepting the Written and Oral Torah.
