“It is not not unprecedented.”
On March 29, Rabbi Janet Marder was installed as the first woman president of the CCAR (Central Conference of American Rabbis, the rabbinate of the Reform movement). In her first sermon, Kos Y’shuot Esa she postulates what the sages might have said when commenting on this historic occasion.
The Sages would have totally ignored the installation of a woman “rabbi” as CCAR president. The Sages did not generally comment on heterodox groups (e.g., the Karaites) unless halacha was affected.
