Should this question about Jewish beliefs be closed for the reasons given in this meta post explaining a moderator's reason for closing a question about atheism and this other meta post that explains another moderator's reason for closing a question on Judaism?
If not, what's the difference?
I tried to vote to close it as off topic, but the open bounty is preventing me from doing that.
Questions about Jewish beliefs are on-topic if they relate to Old testament times, or to New testament times such that they impact Christian teaching, or provide context to the Gospels or other early Christian accounts. In the example given the question in clearly on-topic because it can help with the understanding of the Biblical accounts, the Jews' reaction to Jesus' Messianic claims, and generally with the culture of the times.
I think the question you linked regarding "What were the Jews expecting..." is reasonably on that edge between Christian teachings and the teachings of Judaism.
The question is really about the birth of Christianity. In other words, what did "Jews-following-Jesus" believe versus "Jews-who-didn't-believe" and where, exactly, did they disagree and split? It's exactly that moment where Jewish and Christian doctrine last overlap then diverge. I see that as perfectly on topic.
In a much broader sense, if the question was strictly asking about Jewish teachings — with no reasonable connection to the subject of "Christianity" — I would probably close it. As a site tightly scoped around the subject of Christianity, it's out of scope to start taking about matters of purely Jewish teachings, unless it has a reasonable connection to what you discuss here.
When it comes to Jewish (or any other religion's) teaching, there may be a strong correlation of what you happen to have extra-curricular knowledge of, but that's is entirely different than what is on topic for this site.
I'm not going to tell anyone what to do, but I think that Closed - Can Atheists be moral? ought to be rescinded.
If you don't agree with it, join me and downvote it.
I ask the question here, mainly because I think Christians can have at least as good an understanding of Jewish culture around the time of Christ. And why shouldn't they? It's not like Christianity didn't come directly out of Judaism.
Now regarding atheism, I'd tend to agree with anyone who considers it off topic IF atheism were actually a religion. It has some elements of religion, except no one who is in it considers it a religion.
No member of the faithful could possibly deny that the Church is competent in her magisterium to interpret the natural moral law. (Humanae Vitae, Article 4).
