He did 3 interviews with Art during his life.
The last one he did was the one youre talking about.

Ive listened to it twice and even though he tries to gives us hints he was quite tight lipped about it.

Basically Art reads an alleged copy of the Third Secret of Fatima, and Father Malachi says that its accurate in its description of the destruction and mayhem it portrays but he says that the MAIN REASON why all of that is happening is not mentioned in that "leaked copy" but its explicitly mentioned in the real version of the Secret which Malachi read personally first hand.


My personal opinion on what that MAIN REASON might be, is that its The Destroyer.

Read the Kolbrin Bible to figure out what The Destroyer is.
Its also called The Doomshape.


Its a pretty good reason to not make it public ill tell you that much.
