By conveniently ignoring all evidences, including the consensus conclusion of the overwhelming majority of non-Christian classicists like Geza Vermes and Hyam Maccoby, that Christianity pre-existed Marcion —

IOW, by omitting a heck of a lot of facts —

someone is seeking to give the impression that, as it were, Marcion invented Christianity,

rather than its having been a movement that existed prior to his time, that expelled him because he taught the various strange things mentioned.

Because he rejected TaNaKh, for example.

Because he taught that Jesus was a "ghost."

And so on.

CONTEXT, Sophiee.  CONTEXT.
