Mishneh Torah, Circumcision 2

Sugya Map: The Mechanics of Milah

• Core Issue: Who is valid to perform Brit Milah and what constitutes a "finished" act when the operator is technically disqualified (e.g., Akum, woman, or minor)?
• Primary Sources: Avodah Zarah 27a (validity of woman/uncircumcised Jew); Shabbat 137b (pri'ah as Halacha leMoshe miSinai); Rambam, Hilchot Milah 2:1–2.
• Nafka Mina: Whether a Brit performed by a non-Jew is a ma'aseh mitzvah that requires no repetition, or merely a successful physical alteration that mandates a hatafat dam brit (drawing blood).

Text Snapshot

• Mishneh Torah, Circumcision 2:1: "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..."
• Nuance: The Rambam uses the term "anyone" (ha-kol)—a broad inclusionary clause. Note the dikduk in 2:2: "If he [a gentile] does so, there is no need for a second circumcision." The Kessef Mishneh notes the tension: if a gentile is pasul, why does the act stand?

Readings

• Kessef Mishneh (2:2): Argues the issue is lishmah (intent). If the act of cutting is successful, the status of the child as circumcised is achieved, even if the agent lacked the requisite status to perform the mitzvah.
• Yitzchak Yeranen: Reframes the Rambam via Tosafot (Bekhorot 34a). Even if an act is prohibited to perform (e.g., by a gentile), once the physical state is changed (the foreskin is gone), the result is a milah. The prohibition is external to the ontological status of the child.

Friction

• Kushya: If Milah is a kiyum mitzvah (an act of fulfillment), how can a gentile—who is not commanded—create a mitzvah?
• Terutz: Tzafnat Pa'neach suggests that milah is a hybrid: a physical transformation (guf) and a religious obligation. If the guf is transformed, the obligation is satisfied. The mohel is merely the instrument; if the instrument is flawed, the outcome remains valid because the "flesh" has been removed.

Psak/Practice

The Shulchan Aruch (YD 264:1) codifies that while we prefer a qualified Jewish male, the act is not repeated. Practically, the Rama insists on hatafat dam brit (without a blessing) if the mohel was a gentile, effectively treating the initial act as a physical reality but a religious vacuum.

Takeaway

Milah is primarily an ontological shift in the status of the Jewish body. While the agent must ideally be a bar-mitzvah Jew, the status of the child is independent of the agent’s ritual standing.
