I asked for source material for this accusation and you send this link?
He begins with a premise similar to “When did you start beating your wife?”
“the real question that I will address in this article is: In what way
is Opus Dei behind Vigano’s actions?”
In other words, he already "knows" something.
To a man with a hammer, everything looks like a nail
He goes on with mere speculation:
“For instance, given the aforementioned accolade to John Paul II, could he be acting in deference to Opus Dei’s desire to continue the myth of “John Paul the Great?” Or is there another Opus Dei purpose behind this?”
Being open-minded, I continued to read to see if these thinly veiled accusations were supported. They were not. He repeatedly made unfounded accusations without giving any source.
I checked for footnotes.
One was nonworking.
One was a nothing burger.
Calumny is a sin.
