The World’s Greatest Secret
John Mathias Haffert
Of this book, which sold over 100,000 copies, Saint Padre Pio said: “It will have success during the author’s life but will have greatest success after his death.” John Haffert, the Co-Founder of the World Apostolate of Fatima has gone on to his eternal reward, but the mystery of the Eucharist remains. By reading this book you can be fulfilling a prophecy made by one of the 20th centuries greatest saints and helping yourself to become a better member of the mystical body of Christ through worthy reception of the Eucharist.
