When you can name every congregational leader in the Messianic movement and give me his credentials than I will join in the everyone and no one game.
I think this is a semantic dispute.
ST's point is valid- to his knowledge there's no leader within MJism that would qualify to be called a Rabbi in the sense of a Jewish Rabbi with a smicha. If you find one, let him know.
However, we know that the term "Rabbi" can also apply to teachers who have not received a smicha (ordination), especially among the haredi sects. So, in the sense of "non ordained teachers", perhaps the MJs could use the word Rabbi, but it is highly inappropriate if you ask me and can be misleading. Rabbinical training takes years, and even a Rabbi without a smicha is going to be qualified for his role.
What ST and others are noting is that there is no
standard with which a congregation can be assured that their "Rabbi" has been thoroughly tested. Some congregations perhaps fare better than others, but the worst case scenario is letting self-appointed men start their own congregations and gather people around them. This is a shame and is dangerous.
OTOH, a properly trained minister could theoretically be called a "Rabbi", as he is a teacher. As a matter of fact, even a Catholic priest I know of who visits a Jewish sysnagogue is often affectionately called "Rabbi" by the Jews- a term of respect for his learning and leadership of his own faith community. However, this Priest is not a missionary to the Jews nor their mentor, but a true friend to them. Perhaps his respect for them has earned a mutual respect?
Personally speaking, the Christian ministry, as outlined in the NT, should be what MJs are looking for in their coingregations, not a copycat Jewish Rabbinate.
