In the Jewish tradition, every male child is “marked in the flesh” as a son of Abraham—a keeper of the Lord’s covenant—and formally named on the eighth day after birth.
The Jewish ritual for circumcision is called a bris: the rabbi (Hebrew for “teacher,” as Jesus was called by His disciples!) removes the baby boy’s foreskin with a small knife, as all his family witnesses his reception into the Jewish religious community. Being Jewish, Jesus was circumcised and named when he was eight days old:
"And when eight days were completed for the circumcision of the Child, His name was called Jesus, the name given by the angel before He was conceived in the womb (Luke 2:21)."
The commemoration of His circumcision celebrates God’s intention to perfectly fulfill the promise of the Law through His Son, and foretells the salvation of human flesh through the destruction of death by His bodily resurrection.
