"There are critical junctures in each Gospel narrative where the status quo changes. If everything before and after those junctures reflects a consistency (pre/post status quo) in that regard, then we have more evidence of chronological sensibility in the narrative at large.
For example, someone should do a study of Luke's gospel alone and ask, how many elements in each story-episode would not fit if we 'moved' this episode further backwards or forwards in his narrative. There's a few stories that could slide quite a ways, but there are many more that could only go so far."
Who said this? Me, last November
Why bring it up? I think this is what I need to be working on more, nowadays.
