Who is "Teresa of Lourdes"?
Beyond Matthew, Mark, Luke, and John [and a tiny handful of others], it's all just hearsay.
Interesting take.
Luke tells us the history of Paul in Acts, including Paul's personal encounter with Jesus.
If we are to discard Paul, we must also discard Luke as an unreliable witness.
And that would create further difficulties.
I would also point out that much of the Gospels is inescapably "hearsay" because all four evangelists relate events at which they themselves were admittedly not present.
Maybe they meant Teresa of the Andes?
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.
