That would dovetail with this article.
The new ‘Sanhedrin’ is sort of a voluntary effort and not officially recognized; the problem being, that after the members are named, the automatic response is, “Why is HE on it, and not ____?”
So while there ‘is’ a Sanhedrin, it really depends on what your definition of ‘is’ is....
(AFAIK, there’s no prophecy anywhere in either Testament about the Sanhedrin—though I could be wrong.)
Levites have come to the Temple annually for years to offer the priestly blessing to Israel. So I don’t know if this current meeting is actually something new, or simply a larger version of what has been done before.
i think this group that reconstituted the Sanhedrin believes that the Temple should be rebuilt in our day and that a Sanhedrin would be necessary to authenticate the coming of the Messiah - i don’t know if they are part of this, but there is a group called the Temple Institute which has a wonderful museum/exhibit in the Jewish Quarter of Jerusalem. they have recreated the utensils and vestments from 2nd Temple to be ready for the rebuilding of the Temple in the present day. a fascinating place to visit and see those things we read about in Hebrew Scripture and now can visualize what it all looks like.
