I haven't watched them all yet, but as you suggested took the time now to view #4. I said this before on this forum, I remember that day well when the so-called white then black smoke was seen. Heard it on the radio, they said, the white smoke, we have a pope, then everything was changed to black smoke and the people everywhere were confused.
I also heard many times that there is evidence that John XXIII was a freemason, I think the evidence was in Turkey, but I could be wrong on that, it has been awhile since I read that in a Catholic magazine, titled "The Seraph", not sure this publication is in print any longer.
On this matter I am betwixt and between, since what does it matter much now, all this damage has been done, and I wonder too what does God think of Cardinal Siri about his lack of courage. Yet maybe nothing would have been gained if he did accept his valid election. Since he denied it, however, should we really consider him a pope after all?
Will watch all of the YouTubes and I do want to thank you for doing this research, taking the time to undertake this endeavor, it will, I feel wake up many people.
