Actually yeah, one afternoon He did! He even said as much to His disciples afterward when they asked Him why He started teaching in parables all of a sudden.
(From a harmonization perspective this happened in His second round of preaching on the lake near the Bethsaida fishing suburb of Capernaum after lunch, having previously been charged with Satanic collaboration by Pharisees in the audience when a demented man He had already healed the night before showed up the worse off than ever. The day made a huge impression on His disciples because I found an equally huge block of material from it plopped piecemeal into the Synoptics. The sequence starts about halfway through Chapter 17 of The King of Stories and continues through the first part of Chapter 21. I was amazed to discover how much of that material fit together when I started checking time/place cues and thematic/narrative cues.)
Anyway, I should clarify that I don’t think in the book Rob is (intentionally) trying to be obscure, although I do find in his early interview material he seems to be trying to be intentionally obscure or evasive on some points for whatever reasons–possibly from lack of experience (at the time) talking about it, maybe somewhat for marketing reasons, maybe also because he doesn’t want to lose his audience talking about technical issues. (My complaint about that, ever since I watched the first interview, has consistently been: Rob owes the audience or at least his peers strong reasons, not merely emotional suggestions, as to why he has spoken so strongly against non-universalist teachers and preachers.)
I agree, and will be saying more-or-less the same thing myself (more than once if I recall) in my next part.
(Plus as I go along I have fewer complaints; mainly because he’s talking more about his positive case and so by proportion less about his opposition in various ways–which means he also has fewer opportunities to be fair or unfair to his opposition by proportion. )
