Hi Doug, I have speed read what you have written, and did not spot one Typo, but I too am getting old so cannot swear that I have not missed one !
The only observation I have is that though you make it plain you are dealing with the development of evolution of the Messiah concept by comparing the views as they appeared chronologically, when dealing with N.T writings you have not always mentioned (again) the time period that the Gospel or whatever was written, for the lay reader it may be helpful to always do this. I think with the letter to the Hebrews, and maybe 1st and 2nd Peter you may not have mentioned their time of writing in the sections. To do so underlines that the evolution of the concepts surrounding the Messiah in Christian thought are very late.
Having read what you have written thus far, the last Gospel to be written, that of " John" now seems to me to have as one major motive the tidying up of the various concepts of " messiah" for the Jesus/Christ movement to use, and take advantage of.
Just an irrelevant aside, I noticed the verses from the Gospel of John where the Jews dispute the Messiahship because Jesus comes from Nazareth, does this show that the writer of the Gospel of John was not aware of the anachronistic Census Story in Luke to get around this anomaly, or is this merely a device to show that "the Jews" were ignorant of this story ? I suppose it depends in one way if Luke was generally distributed, being written around 90 C.E , and "John" more than likely a decade or two later, John may not have read it. Although the many points of agreement between Luke and John, and of course the other Gospels, does look as though he was familiar with all three.
