Carl Olson interviewed Paul Kengor over on Catholic World Report. It is a rather enlightening interview and I recommend it. An excerpt:
CWR: The matters of the consecration of Russia to Mary’s Immaculate Heart and the Third Secret of Fatima are still quite controversial in many Catholic circles. What do you think happened, based on your research, and why is there still so much controversy and confusion?
Dr. Kengor: As to the Third Secret, to be blunt, some were hoping for the Apocalypse. They were hoping that the Third Secret predicted the End Times. Of course, this isn’t because they morbidly wanted the world to explode in giant nuclear-mushroom clouds, but because they want Jesus to come again and straighten out this painfully insane world. In that sense, with the Third Secret “merely” predicting the shooting of a pope who didn’t die, I think some people were oddly let down.
Now, that said, I walk through this very carefully in the book: Sister Lucia told the Vatican several times, very specifically, that the Third Secret had been fully revealed and that John Paul II’s consecration of Russia to Mary’s immaculate heart had been done properly and successfully. I have full chapters in the book on each of those two events. To me, the issue seems resolved.
