On one occasion—speaking on Shabbat Rosh Chodesh Tevet, Chanukah 5735—the Rebbe highlighted the significance of the three elements of Shabbat, Rosh Chodesh, and Chanukah.
These three themes—though independent and not always coinciding—reflect two complementary movements that exist throughout Torah and creation: affirmation and negation, the “positive” and “negative” strokes, which together form the wholeness of G-d’s revelation.
Just as the first two commandments, “I am” and “You shall have no other gods,” are considered the root of all the commandments and were heard directly from G-d, so does all of creation carry both multiplicity and unity.
Shabbat, Rosh Chodesh, and Chanukah each express another aspect of this relationship between difference and unity. Their distinctions begin with time itself: Shabbat recurs weekly, Rosh Chodesh monthly, and Chanukah annually. They also differ in history and spiritual essence.
Shabbat dates back to Creation, when the Divine light shone openly for 36 hours. Rosh Chodesh came into its full significance only when G-d chose Jacob and his children, the people whose calendar would sanctify time. Chanukah arose centuries later, in an era when darkness prevailed—the Greek regime sought not merely to disrupt Jewish practice temporarily but to extinguish it entirely. Yet out of that darkness came a light with the power to illuminate the outside world, transforming night itself. This is the essence of Chanukah: not merely resisting concealment, but causing the very darkness to shine.
In personal service, Shabbat corresponds to Torah study, which elevates a Jew above the world, as every Jew is called “a student of the Divine.” Rosh Chodesh does not have the level of sanctity of Shabbat, since work is permitted on it; nevertheless, Scripture does not call it a “day of work.” This indicates one’s engagement with worldly matters—whether necessities or one’s livelihood—but in a manner that lifts action into a realm beyond action, infusing it with holiness. Chanukah, in turn, reflects the power to illuminate the outside world, not only removing concealments but transforming the world itself into holiness.
Ordinarily, these are three distinct modes of service. But when Shabbat, Rosh Chodesh, and Chanukah coincide, the Jew is empowered to unite all three at once: to stand above the world like Shabbat, to elevate the world like Rosh Chodesh, and to transform the world like Chanukah.
