The 43-minute call revealed that, according to the RCA, the resolution banning women from positions in the rabbinate:
a) “passed without any opposition”;
b) is binding upon all members not only as organizational policy, but also as Jewish law or halacha;
UPDATE: Since there seems to be some question as to this point, I’ve transcribed the most relevant portion, which begins at the 36:05 mark:
Rebecca Honig Friedman: Do you regard this decision as strictly an RCA policy resolution, or do you view it as a halachic policy, as well?
R’ Shmuel Goldin: Resolutions that are presented to the RCA for approval have the status of halachic decisions. In other words, this is a resolution that is based on our understanding of the halacha.
It should be noted that the resolution, which was our resolution, was also made in consultation with other halachic authorities…who guide our group, and received their approval, as well.
So the answer is that this is a reflection of our halachic position.
c) is intentionally vague in not delineating what responsibilities or job descriptions given a woman would be considered a violation of this resolution.
