Of all the practices in Judaism, Brit Milah is among the oldest and most continuously observed. For roughly four thousand years, across wildly different cultures, geographies, and historical circumstances, Jewish families have maintained this covenant. Understanding its history deepens the meaning of what remains, today, a profoundly living tradition.
The Biblical Foundation
The commandment of Brit Milah originates in the book of Genesis, where God establishes a covenant with Abraham, commanding him to circumcise himself, all male members of his household, and all future generations on the eighth day of life. This covenant — sealed in the flesh — is described as an eternal sign between God and the Jewish people.
The eighth-day timing has fascinated scholars and physicians for centuries. Modern medicine has confirmed that vitamin K — essential for blood clotting — reaches its highest natural levels in a newborn on approximately the eighth day of life. The ancient wisdom embedded in this timing continues to inspire awe.
A Historical Timeline
The Covenant with Abraham
The biblical account places the origin of Brit Milah with Abraham and his household. Abraham himself is circumcised at age 99; his son Isaac is circumcised on the eighth day — the first recorded instance of the commandment as we practice it today.
The Exodus Generation
According to biblical accounts, circumcision was not practiced during the 40 years of wandering in the desert, and a mass circumcision took place upon the Israelites' entry into Canaan under Joshua. This renewal of the covenant marked the nation's arrival in the Promised Land.
Antiochus and the Maccabees
The Seleucid ruler Antiochus IV Epiphanes banned Brit Milah under penalty of death as part of a campaign to suppress Jewish religious practice. Jewish mothers who circumcised their sons were executed alongside their babies — yet many families continued in secret. The Maccabean revolt, which gave us Hanukkah, was in part a response to these persecutions. Brit Milah became, in this period, a symbol of ultimate Jewish resistance and identity.
Roman Persecution
The Roman emperor Hadrian banned Brit Milah throughout the empire following the Bar Kokhba revolt. The practice was carried on clandestinely. This period also saw the rabbis formalize the three components of the ceremony — milah, priah, and metzitzah — as distinct ritual requirements.
The Mohel as Community Figure
Throughout medieval Europe and the Muslim world, the mohel emerged as a recognized communal religious functionary. In many communities, the role was hereditary — passed from father to son — and the mohel occupied a place of honor alongside the rabbi and the cantor. Elaborate mohel kits (knives, clamps, and vials for wine) became prized family heirlooms.
The Haskalah and Reform Movement
The Jewish Enlightenment (Haskalah) and the rise of the Reform movement in 19th century Germany brought the first significant internal debates about Brit Milah in modern times. Some early Reformers questioned or sought to abolish circumcision. The movement ultimately retained the practice, though with ongoing discussion about ceremony and meaning that continues to the present day.
The Holocaust and Survival
During the Holocaust, circumcision was used by the Nazis as a means of identifying Jewish men and boys. Despite this mortal danger, many families continued to perform Brit Milah in secret in the ghettos and camps. After the war, Brit Milah was among the first rituals revived in displaced persons camps — a powerful affirmation of Jewish continuity.
A Living Tradition
Brit Milah is today practiced by the vast majority of Jewish families across all denominations and levels of observance. In the United States, it is also one of the most common surgical procedures overall — but for Jewish families, it remains infinitely more than a medical act. It is the covenant, renewed in every generation.
Brit Milah in America
Jewish immigrants to America — arriving in waves from the 1880s through the mid-20th century — brought the tradition with them. In the early immigrant communities, the mohel was a vital communal figure, often serving entire neighborhoods of Jewish families. As American Jews spread across the country, the role evolved: physician mohels emerged in the 20th century as Jewish doctors began combining medical practice with religious training.
Today, MohelUSA.org's directory reflects the extraordinary geographic spread of American Jewish life — with certified mohels serving communities from Hawaii to Maine, from Alaska to South Florida. That spread is itself a chapter of the history of Brit Milah in America.
Four Thousand Years, One Covenant
Perhaps the most remarkable thing about Brit Milah is its unbroken continuity. Despite persecutions, bans, dispersions, and debates, the practice has survived and thrived across every era of Jewish history. When a family today gathers around a baby on his eighth day of life, they are joining a chain of covenant that stretches back to the very origins of the Jewish people.
