"The legislative authority now called called "Rabbinic Judaism" began during the diaspora into Babylon."
On what basis do you say this, given your view that the term itself didn't arise for hundreds of years later? You use the presence of the word in the NT as a basis for claiming the NT was written later while simultaneously positing that the rabbinic concept had pre-existed the NT by hundreds of years?
"Side note: The term Rabbi was not used in Jewish literature until after the destruction of the Temple. That fact helps any Jew date (at least the translation) of the Gospels."
That's a pretty strained argument, which certainly begs the question and assumes in advance that the Gospels might not record real history. But it is strained quite apart from the logical fallacy involved. We are to believe that the authors (you imply possibly, the 'fabricators'), while so crafty in immersing the context of Jesus' life in the period from about 1-35 AD (you know, comments about Pilate, things like that) lost sight of their tact and accidentally used the word 'rabbis' ?
That's stretching it, I'd say. back to the point.
It strikes me as a bit odd that you are confronting Christianity with its incongruities with a movement (rabbinic Judaism) that didn't even formally exist- according to you- by any recognizable name until after the destruction of the temple c. 70 Ad.
Surely we as Christians ought to take comments by such folks with a shaker of salt. Wouldn't we be closer to understanding Christianity's Jewishness and their interpretation of the Tanak using pre-rabbinic understandings of Judaism, gleaned from Philo, Josephus, and the Dead Sea Scrolls?
For example, in the DSS there is a document called "The Coming of Melchizedek" which has this passage that cites Daniel 9:
The visitation is the Day of Salvation that He [Melchizedek] has decreed through Isaiah the prophet concerning all the captives, inasmuch as Scripture says, "How beautiful upon the mountains are the feet of the messenger who announces peace, who brings good news, who announces salvation, who says to Zion "Your divine being reigns"." (Isa. 52;7) This scriptures interpretation : "the mountains" are the prophets, they who were sent to proclaim God's truth and to prophesy to all Israel. "The messengers" is the Anointed of the spirit, of whom Daniel spoke; "After the sixty-two weeks, an Anointed shall be cut off" (Dan. 9;26) The "messenger who brings good news, who announces Salvation" is the one of whom it is written; "to proclaim the year of the LORD`s favor, the day of the vengeance of our God; to comfort all who mourn" (Isa. 61;2)
http://www.webcom.com/gnosis/library/commelc.htmIn my 1996 translation of the DSS, the editor points out that: "For our [the composer of the document] author Melchizedek is an enormously exalted divine being, to whom are applied names that are generally reserved for God alone, the Hebrew names el and elohim. In the author's citation of Isaiah 61:2, which speaks of 'the year of the Lord's favor," "Melchizedek" is substituted even for the most holy name of Israel's God, Yahweh. Yet more remarkably, Melchizedek is said to atone for the sins of the righteous..."
The editor also goes into quite a bit of time talking about the jubilee year, etc, and its connection to that document here and in other DSS documents, and largely corroborates what the Christian said in one of the links above.
I also have trouble perceiving that the Rabbis were really God's idea for dealing with a scattered people. Correct me if I'm wrong, but according to the prophets and the writings, wasn't this scattering the result of disobedience?
Anyway, I'm curious about your side note about 'rabbi' being used only after the destruction of the temple. I'm almost curious enough to scour Philo to see what can be found. Still, the simplest conclusion I draw from what you said is that Rabbinic Judaism actually didn't get started until after Christianity started.
