I did not intend to make an argument from authority. It was you who called the references I gave "fringe Biblical scholarship" that you were not interested in reading. Going into details about Howard, Trobisch and Ziesler was meant to be a direct response to that comment. It was not meant as "proof" that the Tetragrammaton was in the NT, just that I think they are scholars worth reading if you are interested in the subject. Most scholars would dispute the claim the NT originally contained the divine name, that is clear. The reason I mentioned Trobisch in the context of discussing the nomina sacra on the other thread is that he makes an interesting case linking the nomina sacra present in extant NT manuscripts with the Tetragrammaton used in the early LXX and argues for the likelihood that the NT also originally contained the Tetragrammaton. The development of his argument takes up about 12 pages of text and 7 pages of endnotes. If I could reproduce it here for everyone to read I would. It is because the argument itself is good that I mention it, not to invoke the name of a scholar for the sake of it. You rarely rely upon secondary sources in making your arguments whereas I rely upon them heavily. I think that is understandable considering you can read biblical languages and I can't. I am not in a position to dispute inferences based on linguistic evidence you draw from texts under discussion. I am in a position to point to scholars who disagree with your position and point out where I feel their reasoning is persuasive. That is what I have attempted to do.
Although you quote me from the thread I wrote to reniaa, I have demonstrated that I can see both sides of the argument:
I think I showed the Watchtower writer is pretty misleading in how he presents his case. However there are a few things I have changed my mind on since making that post. Having read Tov's response to Pietersma I think the evidence is good that the original LXX used IAW not kyrios. Frank Shaw's dissertation also persuades me that forms of the divine name were in everyday use much longer than is generally believed and that some Jews used the divine name in everyday contexts in the first century. (I am just explaining here what information caused me to change my mind if anyone is interested, not insisting that anyone else must believe any particular thing just because some scholar I name said it!) The biggest problem I still have with the Watchtower's argument is that they try to have it both ways: they claim the NT has been well preserved so we can be confident about the text; yet an element of the text as significant as the divine name is said to have been removed. I am not in the position of having to hold those two contradictory positions. I believe the NT underwent significant revision in its early transmission, including the removal of the divine name and introduction of nomina sacra.
Ziesler's argument in Romans 10 if I remember it correctly is that the five "fors" link "everyone who calls on the name of Lord will be saved" in verse 13 with "believe in your heart that God raised him from the dead" in verse 9, not "confess with your mouth that Jesus is Lord" as most scholars see it. And it makes sense of the passage:
8But what does it say? "The word is near you, in your mouth and in your heart" (that is, the word of faith that we proclaim); 9 because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.10 For with the heart one believes and is justified, and with the mouth one confesses and is saved. 11 For the Scripture says, "Everyone who believes in him will not be put to shame." 12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. 13 For "everyone who calls on the name of the Lord will be saved." (English Standard Version)
Paul says that Christians who confess Jesus is Lord and believe God raised him from the dead will be saved. It is God's demonstration of power in resurrecting Jesus that is the guarantee of salvation. The subsequent clauses beginning with "for" are thus each linked with the action of God in raising Jesus from the dead, so that the Lord who is "Lord of all" that Paul has in mind is God who has the power to resurrect from the dead. Thus Paul also has God in mind when he quotes Joel 2:32: "for everyone who calls on the name of Jehovah will be saved". (NWT) When the Tetragrammaton was present in the text the point would have been clear. Since it was removed it is understandable that most readers have taken the "Lord" Christians confess in verse 9 to be the same "Lord" they call upon in verse 13. Yet interestingly Ziesler argues that the distinction between the two Lords is present even without positing an original Tetragrammaton. He argues that readers would have known that the Lord of the OT is a different Lord than Jesus in part because the Tetragrammaton was preserved in the copies of the LXX that they read.
