Actually, the Jewish canon is entirely originated in Hebrew or Aramaic, both ancient languages that existed concurrently. There is today only a modern Hebrew, Aramaic has descendant languages but has itself gone extinct other than as a scholarly and priesthood language, much like Latin has, though Latin came later.

Yiddish is a language used by modern Jews of European descent long after diaspora. Most Yiddish Jews have little if any Hebrew ancestry. The author was noted after the opinion article to have specifically been a HEBREW Jewish Rabbi. He would have been selected to become a rabbi at birth and been studying the original languages and the scriptures as well as histories and laws etc from birth. I would be far quicker to trust his judgements on his peoples history than I would any other Jew, let alone a Christian or someone who purports to be a religious scholar but only started to study a broad spectrum of religions from a late age.

Hebrew is the ancient and still living language of the Hebrews. They are a people who may or may not be Jewish, Judaism is a faith, not a people. Therefore, quite simply, a Hebrew Jewish Rabbi is a much better authority on Hebrew and therefore Jewish history than any other profession since Judaism started as a Hebrew faith.

And what I find interesting, is, no matter which sect they follow, ALL current HEBREW Jewish Rabbi's seem to be saying the same thing as this one. At this point, anyone questioning this are the ones to be asked to back that up, and, not surprisingly, they always fail to put forth a convincing argument, pushing for later translations or sectarian non-canonical works to be considered proof positive of their argument.

Canonical Hebrew and Aramaic texts for the Bible are still extant, they've been preserved despite all the things the Hebrews as a people have been through. Also still extant, preserved through all their history, have been a large chunk of their historical records, including their laws. As a HEBREW Rabbi, the man who wrote this opinion piece has been studying these records, in their original language, all his life. That's his JOB. I'll readily consider him more authoritative than some other random person who only just started studying this stuff recently in translated form.

There's still a lot of opinion here, of course. The same words that he interpreted to mean that the Abrahamic God is gender fluid COULD also be interpreted to mean that the Godhead includes more personages than one, and at least one of those personages is female... there's really no way to know what was meant, and he's interpreting it just as much as we are. The fact that he's interpreting it from the original, though, and with far more context than we non-Hebrews have, lends quite a bit more credence to his theorizing and opinions than most though. Especially since every Hebrew Jewish Rabbi are saying the same or at least extremely similar things.
