Professor Rory Boid's Take on Secret Mark

I don't know any Greek. I am familiar enough with modern Greek to raise my eyes to heaven when Americans go into a restaurant and order 'gyros' but that's it. I think Professor Hedrick has had just about enough of my endless questions about the exact nuance of each sentence in To Theodore so I turned it over to someone else. I asked my friend Professor Rory Boid of Monash University what he thought To Theodore was saying about the composition of various gospels in the text and here is his take on matters via email:

I think it means Mark first wrote something in Rome good enough for Peter’s use, and then wrote the real gospel in Alexandria after Peter died. I think this means both the exoteric and esoteric gospel were written in Alexandria. The new exoteric gospel superseded the version written in Rome, called “Peter’s notes” later on.

One more unforeseen implication of To Theodore's chronology - it seems to confirm the critical understanding of the gospel being written around 70 CE. Interesting.
