Breaking News - Markus Vinzent's Next Book Will Argue that the Marcionite Gospel is the Source of Both Canonical Mark and Luke

I am writing this on the go but when I woke up this morning I saw a conversation between Markus Vinzent and his publisher confirming their interest in publishing his follow up book to Christ's Resurrection in Early Christianity and the Making of the New Testament which will be released later this year. I have always been arguing for Marcionite primacy as have a few other bloggers. But never before have we had a man of this stature making the argument for us. Vinzent tells me:

And, Stephan, be assured - the book will cover the entire text of the Gospel - in a synoptic reading with the other Gospel-texts (and other early Christian writings).

Vinzent will seal the deal. I know that with absolute certainty. However my readers should be aware of the implications for 'Secret Mark' research.

If there was a text which combined Markan and Lukan elements which stood behind canonical Mark - how can anyone argue against the implausibility of the Letter to Theodore's 'Secret Mark'? Remember also that von Harnack and others have noted that there is no John the Baptist dunking Jesus at the beginning of the gospel narrative. So whence does the Marcionite justification for baptism come from? Epiphanius makes clear that their 'redemption' ritual comes from the equivalent of Mark chapter 10, the exact same place as LGM 1.
