At the Brit Milah parents give name to their son. Is there a seperate ceremony or is it part of the Brit Milah? And does this name-giving-part have a name?
While it is a separate section of the ceremony. it is part of that ceremony and done at the same time. Since the child as a member of Bnai Yisrael is entering the "covenant", he is given his identity at that moment. It is called kriyas hashem (calling or announcement of the name). Thus the person who will read the bracha that gives the name is announced
Rabbi Ploni is honored with kriyas hashem
As @DoubleAA points out the person does not have to be a rabbi and the announcement can be made in any language. I just gave a typical example.
@msh210 points out that this is actually not a requirement of the bris even though most people do so and make it an "honor".
It would appear that it is a part of the actual ceremony, albeit obviously not integral (מעכב).
- The text of the naming ceremony contains many explicit and implicit references to ברית and מילה
- ואעבור עליך ואראך מתבוססת בדמיך ואמר לך בדמיך חיי ואמר לך בדמיך חיי
- 'זכר לעולם בריתו וגו
- 'אשר כרת את אברהם וגו
- ויעמידיה ליעקב לחק לישראל ברית עולם
- 'וימל אברהם את יצחק בנו וגו
- 'כשם שנכנס לברית וכו
- When the same person makes the naming as the ברכות, the wine is drunk after the naming, clearly rendering this an extension of the ברכותת, otherwise it would be a ברכה לבטלה.
