Rabbi Avi Weiss is changing the title of Maharat Sara Hurwitz to Rabbi Rabba, a title that at least sounds like clergy, as Maharat is a contrived and convoluted word that means absolutely nothing to people not in the know. It means absolutely nothing to me, and I am in the know. Either way, Sara Hurwitz is great at what she does, far beyond a vowel’s power to add or subtract.
