You know that what you are asserting teeters on a good approximation of dates; that St Paul’s epistles likely predate the synoptic gospels and a Q as theorized; gospels stories were oral traditions long before being transcribed; each evangelist was evangelizing a different culture; and each evangelist was likely comprised of multiple disciples; synoptics took on Q-like coloring from the regional blending of a single report. Everyone has a different perspective of the parade. Would you consider that the while the synoptic gospels are titular, they may not have been written by their namesakes? Scholars aside, it is amazing that each extant Gospel copy is remarkably identical. Deducing that the Beatitudes was not a single Sermon on the Mount event is brilliant. World War II was more than the Allied invasion of Normandy. Redefining history in this way imparts little value to the occurrences described. The argument of Q and who is who is literary more than historic in substance - scholarly.
