When can't you be a rabbi?

Answer 1

The question is very ambiguous ... we are left to try and figure out just what the questioner

hopes to learn, before we attempt an answer.

Here are some characteristics that would bar an individual from being ordained to the rabbinate:

All groups within Judaism:

-- non-Jew

-- age less than 13

-- insufficiently educated in Judaism

Some groups within Judaism but not all:

-- non-Sabbath-observant

-- unmarried

-- female
