There is no requirement in old covenant law for a child to be named on the day of his circumcision. The fact that this was what happened with Jesus is meant to draw a parallel between him and John (Luke 1:59–64). John is the forerunner who points to Jesus, the final prophet of the old covenant (Luke 16:16). Jesus is superior to John and has come to inaugurate the new covenant (Hebrews 8:6).1
21 Le huitième jour, auquel l'enfant devait être circoncis, étant arrivé, on lui donna le nom de Jésus, nom qu'avait indiqué l'ange avant qu'il soit conçu dans le sein de sa mère.
