Lucas 2:21

And when eight days were fulfilled for circumcising him, his name was called JESUS, which was so called by the angel before he was conceived in the womb.

MOSAIC CEREMONIES FULFILLED FOR JESUS

Not a jot or a tittle of the law was broken by Jesus. He was born under the law and fulfilled all of its requirements perfectly, thus achieving the true righteousness to be made available to all men "in him," that is, through union with and identification with Christ.

Since the purification of Mary, mentioned a little later, and the circumcision of Christ were commandments of the law, they were obeyed. Barnes pointed out that just as Christ was baptized to "fulfill all righteousness" (Matthew 3:15), it was also proper that he should have been circumcised. "It is necessary for the future usefulness of Christ; without it, he could not have entered any synagogue, or had access to the people, or have been regarded as the Messiah."[22]

As in the case of John the Baptist, and according to custom, the formal naming took place at circumcision; even though, in both cases, the name had been given before that event.
