You know, Shermana, I am running out of patience. I'm trying to give you honest answers, and it sounds like you are only trying to catch me out.
Change your tone, or I'll put you on Ignore.
I guess its also a personal problem for the scholars who agree to this too. So if I have a Theological text-based disagreement, it's a personal problem on my part? Was it a personal problem for the Rabbis who didn't want to include Qoholeth back in the day?
I don't know what scholars you are referring to who are currently disputing the validity of Ruth.
This has nothing to do with the scholars who, before the canon was decided, disputed Kohelet. They disputed it, and at the end of the day, even the disputants agreed and accepted it into canon.
You and your recent "scholars" have no call to put into question what has been considered holy for thousands of years, unless you want to display your utter disdain and contempt for Jewish tradition.
I suppose that is your right, but then I would have the right to not take you seriously, if at all.
Where does it say she made the full conversion? In the Talmud?
I imagine you missed the whole iconic verse 1:16 which says: But Ruth said, "Do not urge me to leave you, to turn back from following you. For where you go, I will go; where you will lodge, I will lodge;
your people are my people, and your God is my God..."
That is a declaration of intent. If you need further clarification that Ruth converted, then you might need to look in the Medrash.
But the model for how to deal with a convert candidate is right here in Ruth, including turning said candidate away three times.
If you need more convincing, you will have to explain what else you need.
So then, at what point did being "Jewish" go from a tribal-based classification system for all the Hebrew tribes to a catch-all for anyone who converted including the "righteous strangers"?
That is hard to say. Jonah referred to himself as a Hebrew. Mordechai - cousin and father figure to Esther - is called a Jew in the book of Esther, even though he is from the tribe of Benjamin.
Deuteronomy 7:1-5 forbids non-Jewish men from marrying Jewish women, but no such restriction for Jewish men marrying non-Jewish women....
It isn't listed there in black and white, but it is also a forbidden union. Or have you missed the plague in Numbers because the Jewish men sinned with the Midianite women, including Phineas' spearing of Cozby and Zimri?
But....., on the previous subject feel free to explain why the foreign wives in Ezra 10:2-3 weren't even given the chance to convert. Why were they just cast away?
They had the entirety of their marriages up until that point. If the women didn't convert YET, they probably weren't going to start right then, either.
Now what term can we use to describe this difference? At what point does "Biological" differ from "Racial"?
Again... Why is the designation of race so important to you?
