The same Fr. Kramer that wrote Book of Destiny?
No. That's a totally different priest (Fr.
Bernard Kramer).
Since you mentioned it... reflecting on some of the things I remember reading in the Book of Destiny, I think it's far too speculative to be of benefit to someone looking for insight on the Chastisement or End Times. Thank God for giving us the saints.
And I hate to say it, but I think the book is tainted with a sci-fi influence.
That's why I don't recommend it to anyone.
Anyway... I have not yet read Fr.Paul Kramer's new book, but I know it will be good.
