No. In fact, most countries in the world do not have chief rabbis.
But if the synagogue has more than 1 rabbi, the Senior Rabbi should be present if possible.
Yes. It makes it official.
I think a Conservative rabbi or Reform rabbi would know.
A Chief Rabbi
Their last Chief Rabbi was Rabbi Chalom Messas (1961-1978).
The Chief Rabbi is in charge of the Jewish community in the country he lives in.
Rabbi Riccardo Di Segni
Prior to the year of their bar mitzvah, after sundown on Passover.
Sir Jonathan Sacks is the chief rabbi
Chief Rabbi Sir Jonathan Sacks. He is the religious leader of the Jewish community in the UK. Rabbi is a Jewish word meaning Teacher.
A Rabbi, the boy, his friends and family are all involved in a Bar Mitzva.
You need to ask a Conservative or Reform rabbi about that.
Yes Geoff Schwartz is Jewish. At his bar mitzvah the rabbi had to stand on a stool to reach him.
