Mishneh Torah, Circumcision 2

Hook

Why does the Rambam permit a non-circumcised Jew, a slave, or even a minor to perform a brit milah, yet disqualify a gentile—even though the physical outcome of the procedure is identical?

Context

Rambam’s ruling in Hilchot Milah 2:1 is grounded in the Talmudic debate (Avodah Zarah 27a) regarding who possesses the "legal capacity" (hechsher) to perform a ritual act. The historical tension rests on whether circumcision is merely a surgical removal of flesh or a formal act of covenantal entry requiring a "covenantal agent."

Text Snapshot

"Circumcision may be performed by anyone... Even a person who is himself not circumcised, a slave, a woman, or a minor may perform the circumcision... A gentile, however, should not be allowed to perform the circumcision at all. Nevertheless, if he does so, there is no need for a second circumcision." — Mishneh Torah, Circumcision 2:1

Close Reading

1. Structural Leniency: Rambam prioritizes the result (the child is circumcised) over the status of the agent, provided the agent is within the fold of the covenant.
2. Key Term (Lishmah): The Kessef Mishneh suggests that the gentile is disqualified because he cannot act lishmah (for the sake of the mitzvah), as he is not bound by the commandment itself.
3. Tension of Validity: There is a paradox: the act is forbidden to be done by a gentile, yet once done, it is retrospectively valid—the "covenantal mark" is indelible.

Two Angles

• Rashi vs. Ramban: Rashi often views the mohel as a required agent of the commandment. If the agent is excluded, the act fails.
• The Kessef Mishneh: Argues the Rambam holds that once the foreskin is gone, the "covenantal state" is achieved, even if the "covenantal process" was technically flawed by the agent's identity.

Practice Implication

This halakhah teaches us to distinguish between the process of a mitzvah and the status of the person performing it. In daily life, it reminds us that while we must strive for the ideal "agent" (the mohel), the ultimate sanctity of a religious milestone often persists even when the human administration is imperfect.

Chevruta Mini

1. If the gentile’s act is valid, why do we maintain the strict prohibition against using them?
2. Does the requirement of metzitzah (suction) suggest the mohel is a medical provider or a ritual conduit?

Takeaway

Circumcision is a physical transformation that, once completed, creates a permanent status, even if the human instrument lacked the proper covenantal standing.
