I'm only 20 minutes into the talk, but I wanted to point out how
Mr Giuffre entirely misrepresents a quotation from Cardinal Journet.
To set the context, they are discussing the idea that the indefectible Church will defect and become a false institution. Beginning around 16:15, Mr. Guiffre begins discussing a quotation he recently discovered in which "the great 20th century theologian," Cardinal Journet, says such a thing is "possible" (16:37; 16:47), and provides a theological basis for how it could happen.
He then reads this quotation.
Cardinal Journet: "But the apostolic body can be indefectible only in virtue of an uninterrupted succession. Suppose it had failed, and then been replaced by another institution to all appearances identical: apparently nothing would have been altered, but in point of fact everything would have been subverted; and this would quickly become apparent. Naturally, both God and Christ would remain untouched; but the institution claiming to take the place of the apostolic body and separated from it by a break, would be a new institution, and could not be that indefectible institution set up in the world by Christ. It would therefore inherit none of the mysterious privileges attached by Him to the true apostolic body; it would have but a simulacrum (simulation) of the power of order, a simulacrum (simulation) of the power of jurisdiction, and any appearance of permanency would be illusory. From this standpoint, the need for an uninterrupted succession in the apostolic body, apostolicae succionis praerotativa, is obvious. Without it, the last link of the chain by which the Church is suspended would be broken, and the divine apostolicity of the Church would have foundered.” (The Church of the Word Incarnate, p. 527)
As should be evident from the context, he is not saying it's "possible" (16:47) that "the apostolic body"
can defect by a break in the succession. He is saying the opposite, and proves
why the apostolic body must be
indefectible by explaining what would happen if it were not.
The cardinal goes on in the following pages to further explain why the apostolic body must be permanent, how it is God Himself who sustains it, and that it's a part of
mark of apostolicity that the true Church will always possess.
Not only has Mr. Guthrie interpreted Cardinal Journet as meaning the exact opposite of what he really meant, but the Cardinal goes on the ridicule those who predict that the visible Church or its visible hierarchy can fail. "In every age" wrote the cardinal, "there have been great men, the 'prophets of this world,' who have predicted the end of the hierarchy, the end of the Papacy, and the end of the Church. It was never the end of the Church." He goes on to say "the persistence of the apostolic body will go on to the end of the world..."
How many people will listen to the interview and come away believing Cardinal Journet held to the possibility that the indefectible Church could defect, and provided a theological basis for how it could happen, when nothing could be further from the truth.
