It is in a book. Something people used to read before internet. They can be found in libraries and various other places. This can be easily verified. Does anyone else have the book by Fenton, written in 1958 so Ladislaus will no longer think I pulled that stuff out of my hat. He gives me more credit I serve crediting with a ten point list directly from Fenton.
Just so you know the direct quote in the OP is verbatim from Monsignor Fenton's THE CATHOLIC CHURCH AND SALVATION, the very end of chapter seven.
I found this cited in one place on the internet, and it was clearly a third party summary of what Fenton actually wrote, and it wouldn't be the first time you combined your own thinking with that of Fenton and claimed that it was his.
Regardless, if Fenton did write it, then Fenton too fell into Pelagianism. He felt the need to accept and justify the Pelegian-heretical Suprema Haec, and so he ended up rationalizing Pelagianism instead of standing up for the truth. In the end, Fenton caved on Vatican II, claiming that Catholic ecclesiology had not been changed but, rather, improved by Vatican II.
Fenton wrote this in 1958. You have no idea what you are talking about when you falsely accuse me of stuff. Twice you have told me my articles are 90% me and both times I have proved you to be 100% the opposite of correct. And you disappear from the thread. But instead of being humbled you accuse me falsely again.
Ladisluas calls one of the very greatest Catholic theologians of the 20th century Pelagian.
What does that make Ladislaus? Not much. Not only do you err in the extreme in regards to infallible doctrine but you cannot get your facts strait.
The facts are verifiable in regards to what I wrote and what Fenton wrote. Order the book and read it for yourself, so you can realize how wrong you are and not own up to it again.
