Who teaches in a synagogue?

Answer 1

That would be a perfectly acceptable practice, but it's not necessarily the Rabbi's

job. Any adult (13 or older) Jewish male who is capable of preparing the portion

and reading it competently may present the public Torah reading.

In some larger, wealthier congregations, the reader is a paid position on the professional

staff. In other congregations ... such as the one I attend ... the Torah reading is presented

by as many as 10 or 20 different members, who are able and willing to do it and who volunteer

on a rotating basis. And in still other congregations, the Rabbi may be the only person available

and capable of reading the Torah.

Note that a Jewish worship service does not require the presence of a Rabbi, and

there are many congregations that function just fine without a Rabbi. Also, there

are others whose attendees include several ordained Rabbis. With Judaism having

evolved in as many as 140 different countries, there is a broad spectrum of small

details in today's synagogue services.

Answer 2

Any individual who is sufficiently knowledgable as to gather a group of willing

students may teach in a synagogue, although it's most often a Rabbi, simply

because that's a major function and responsibility of a Rabbi; and an individual's

ordination as a Rabbi is the qualification that indicates that he has the education,

and probably knows what he's talking about.

Answer 3

Yes. Many synagogues have their own religious schools.
