I have no inside information in the Vatican, obviously. So, the sourcing of the alleged statements, both from OnePeter5 and Vatican Radio, I cannot properly evaluate. Yes, I mentioned the Vatican Radio report when I said "alleged" statements.
The 1P5 report was based upon hearsay, in that the words of Pope Benedict are attested to by a third party-- a priest in the trust of the blog's author, Steve Skojec. The report may be accurate or not, I'm just mentioning the hearsay nature of the source. So, that weighs the scales in favor of Vatican Radio, yes?
No. The Vatican Radio report is also hearsay, and in fact we have no information on the person reporting Pope Benedict's words, or how they were obtained. All we have is the assurance of the communique from the Holy See press office that Pope Benedict said them.
As an aside, I don't trust the veracity of Vatican Radio on the subject of Fatima, as if there has been a cover-up of the Third Secret (as there has undoubtedly been; open-minded skeptics can begin reading here), this is the type of release we would expect. And in this pontificate my trust level has gone way down. I have a high regard for Mr. Skojec's work, but to be fair I cannot analyze his report based upon the source either.
As a result, let me just analyze the alleged statement from Pope Benedict as related by the official communique:
Recall that no matter what the reality is, by definition one of these bishops in white we have today IS NOT THE POPE. The obvious correlation with the Third Secret's vision released in 2000, when none of this could have been humanly contemplated, should put us on guard about the heady nature of these times.
One other way of parsing this, a notion made in the past, and discussed extensively by Antonio Socci, is that the entire Fatima secret semi-release and cover-up involves a large scale mental reservation, but in the end is true-- the vision, JPII's statements at Fulda and at the beatification ceremony of visionaries Francisco and Jacinta, the Marian apparition at Akita, and other Vatican press releases, taken together and in their entirety, have produced a full release of the Third Secret overall.
