“They were going

To name him

Zechariah,

After his father.”

 

καὶ ἐκάλουν αὐτὸ ἐπὶ τῷ ὀνόματι τοῦ πατρὸς αὐτοῦ Ζαχαρίαν.

 

Luke said that they were going to name him (καὶ ἐκάλουν αὐτὸ) Zechariah (Ζαχαρίαν), after the name of his father (ἐπὶ τῷ ὀνόματι τοῦ πατρὸς αὐτοῦ).  The naming of the child was not associated with the circumcision until later.  Christians often call the baptizing of their infants Christening when they give a Christian name to the child, after infant baptism became popular in the early Middle Ages.  Interesting enough, the Hispanic or Sephardic Jews name their children after their parents, while the Ashkenazic or Eastern European Jews name their children after dead relatives or grandparents.  However, today, naming a Jewish boy and circumcision take place at the same time.  For girls, it had become usual to name the girl at a Torah reading on the Sabbath.
