Stand in amazement! At least some parts of the Gospel of Marcion have the most primitive/oldest versions of the Gospel resurrection story. This includes Qn 24.1, which is almost certainly used by Mark. Matthew in turn uses Mark, and Late Luke uses Qn apart from and yet through Mark (our third, dependent signal type).
I’m continuing to build up more evidence, analysis and proofs everyday and will plan to share a big supplement to the book no later than July 31.
