I have heard of chief rabbis and the rabbinate in Israel, and there is even a chief rabbi in the UK (Sacks I believe). In the popular press they are often quoted as representing “the Jews”.
But in my American Reform congregation we never even speak of a “chief” Rabbi…we just have our Rabbi.
This leads me to believe that certain movements of Judaism have chief rabbis and need them for their traditions—but others perhaps do not.
Which movements/denominations/sects of Judaism (and in which countries) need/use a “Chief Rabbi”? And which ones do not?
