In response to your request to answer this question:
No, I do not maintain that, for the very good reason that the verses in question are not ones that I “cherry pick,” as I’ve been at some pains to state already.
One element in critical study of Scripture, IMO, is to identify what particular stories and teachings are preserved across those variously slanted portraits. The story of the feeding of the 5,000, for example, appears in all four gospels. Whatever the truth behind it, it must therefore represent something that (a) is an early and widespread tradition regarding Jesus, and (b) carries some importance doctrinally. There are three different accounts of where Jesus teaches the two commandments he deems the most important – in one of which he commends someone else for identifying them as the most important, in the other two of which he himself promulgates them as most important in two distinct scenarios. A similar application of the principle noted suggests that this too was deemed central to his teaching.
There is, of course, much more to my idea of proper critical study than that, but it seems pointless to reiterate it under these circumstances. But that one principle and two examples should provide evidence of why I don’t consider it cherry-picking.
By the way, two points about the dating:
As PRR validly stated, the dating of the Gospels is important in determining how reliable they might be. Granted, his apparently inadvertent use of “100 years or so” for “a substantial period of time” led to an excursus on the subject of dating. But his basic premise was valid. Something only recorded decades later is less likely to provide accurate information than something recorded closer to the date of occurrence, ceteris paribus.
Second, when Tom inadvertently made a false statement about dating of the Gospels (although his intent to reference statements in this thread, in regard to which he was accurate, was I think clear), I did post a corrective in the interests of factual clarity. And while AFAIK he has not had occasion to do so in this thread, he has several times in the last month or two corrected me on inadvertent errors of fact regarding religious issues – one that comes quickly to mind was whether or not Catholic deacons could bestow the Church’s blessing, e.g., on a newlywed couple. In point of fact, they can; I had erroneously stated that they were not empowered to do so.
