The short answer
For males, traditional conversion requires entry into the covenant of circumcision; if already circumcised, a symbolic drawing of covenantal blood (hatafat dam brit) is typically required. The act marks covenantal belonging, not only a medical procedure.
Why people ask this
Many are surprised that being already circumcised is not enough in traditional practice; understanding the covenantal, not merely surgical, meaning explains the additional act.
Key terms
- Hatafat dam brit /ha-ta-FAT dam brit/
- A symbolic drawing of covenantal blood for an already-circumcised male.
Jewish perspectives
- Traditional: the brit is covenantal; a previously circumcised male still requires hatafat dam brit to mark the covenant.
- Some non-traditional communities treat medical circumcision alone as sufficient for the requirement.
Scholarly & historical context
Circumcision as the sign of the covenant is biblical (Genesis 17); the rabbinic refinement for already-circumcised converts developed in the Talmudic period.
What is agreed upon
For males, traditional conversion includes entry into the covenant of circumcision.
Where the disagreement begins
Whether medical circumcision alone suffices or whether hatafat dam brit is additionally required, and how medical conditions affect it.
Practical consequences
Ask the beit din in advance what is required in your case, especially if you are already circumcised.
