A small group of friends and family gathered to celebrate Max's Bris at the singer's home in Beverly Hills.
The Bris is a ceremony to welcome an infant boy into the Jewish faith through circumcision, traditionally held eight days after his birth.
Max's middle name Liron - "my song" or "my joy" in Hebrew - was made official at the event, which was followed by a special meal.
A source close to Aguilera said: "Christina wanted to give Max a partly Jewish name. When she came across Liron she couldn't believe her luck because as well as liking the sound of it, it was a direct reference to her own career."
The 27-year-old and husband Jordan Bratman welcomed their first child on January 12, a day later than originally reported.
She recently revealed that she was "still sore" a week after the birth.
