At John 19:5 we see:
So Jesus came out, wearing the crown of thorns and the purple robe. Pilate said to them, “Here is the man!”
Elsewhere, we see Jesus referring to himself as Son of Man on numerous occasions.
My question is: Was Pontius Pilate a secret beneficiary of the teachings of Jesus so that he was able to quote the very words of Jesus in his pronouncement during the latter's trial? What do the teachings of Catholic Church say about such a prospect?
