Detraction plain and simple. I guess John Daly is a V2 liber as well. Right Ladislaus. He respects Fenton and his theology on BOD and quotes him at length on the issue.
Well, there are only two logical possibilities, Lover of Heresy, when Fenton claims that Vatican II ecclesiology does not change traditional Catholic ecclesiology and even improves upon it:
1) Fenton's ecclesiology IS in fact identical to that of Vatican II
OR
2) Fenton was too stupid to understand that Vatican II had changed Catholic ecclesiology.
You yourself implied #2, saying that Fenton lacked the "benefit of hindsight". What hindsight? Vatican II ecclesiology was laid out in black and white. Did Fenton not know how to read? Was he not a trained theologian who could be trusted to properly "understand" the actual text of Vatican II?
In either case, #1 or #2, this discredits Fenton as an authority on ecclesiology.
Oh, wait, I forgot, there is a THIRD possibility:
Fenton neither had a modernist Vatican II ecclesiology nor did he fail to understand Vatican II, but Fenton was right and V2 ecclesiology is perfectly Catholic and sedevacantism is just a bunch of schismatic crap.
