That goes too far (as did the previous post to which I objected).
You seem to be setting up an either/or test for Scripture (and by extension, to Christianity as a whole), that is not needed and possibly harmful.
I see the point -- but I think it's possible to take such points too far.
Excluding Paul from Christianity is going too far.
If insisting on Paul is too strong, what then would qualify as being too weak a standard?
That road leads to Jesus Seminar land, in my opinion.
