I read the credit to the author, what I did not see is from where the author got the quote; the original writing of Pelagius in which he said that.
I have googled it several times and there is not one single hit on a source other than this author.
That is what I mean by authenticated.
Give me the original attribution to Pope Pelagius, an official document wherein he says this.
If you cannot, then retract it.
Otherwise, it is exactly as I said, the quote was meant to defame not edify.
