I guess for someone who considers sworn statements from three distinguished Priests (one being a Prior of the International College of the Servites of Mary in Rome), in addition to a sworn statement from the Cardinal who held the position as Vatican Recorder in 1948 to be hearsay. This support would not be taken lightly by anyone who has an ounce of rational thought. Do you have a Last-Will-And-Testament? That is supported by only two witnesses, (not even Roman Catholic Priests or a Cardinal, as in this case)., and that would be valid, in the USA, even if you were a billionaire.
The three Priests were advised in 1947 by His Excellency Monsignor Alphonse Carinci, who was then Secretary of the Sacred Congregation of Rites and Reverend Augustin Bea, who was then confessor to Pope Pius XII to present typed copies to His Holiness Pope Pius XII. They were specifically steered around Cardinal Ottaviani who was famous being contemptible and vindictive.
The validity of Valtorta’s writings have been argued by competent authorities for years, just as we are doing now, so I pasted a couple of supporting competent authorities below.
Father Padre Pio was a great advocate of Maria Valtorta’s writings, and known to recommend reading the Poem on many occasions. There is even a book on the subject; “Maria Valtorta and Padre Pio”, this is why the Knights of Columbus are such avid Valtorta supporters. One year before Padre Pio’s death, a woman named Mrs. Elisa Lucchi asked him if he advised reading Maria Valtorta’s writings. He replied, “I don’t just advise you, I order you read them!”.

“Still feeling subject to acceptance of, and submission to, the original Papal order that they heard with their own ears, the Servite priests gathered a huge amount of support to present to the Vatican. This backing included certifications of Maria Valtorta’s writings from The Secretary Of The Sacred Congregation Of Rites Archbishop Monsignor Alphonse Carinci, from Father Bea, S.J., from The Dean Of The Lateran Theological Faculty and Consultant To The Holy Office Monsignor Lattanzi, from The Dean Of Consistorial Counselors for the Holy See and a teacher at the Lateran Professor Camilo Corsanego and from the renowned Mariologist Of The Pontifical “Marianum” and Lateran Theological Faculty Father Gabriel Roschini, OSM. (As a note, Pope John Paul II called Father Gabriel M. Roschini one of the greatest Marioligists who ever lived. He was a decorated professor at the “Marianum” Pontifical Faculty of Theology in Rome, and an advisor to the Holy Office. He wrote over 130 Books on the Blessed Mother, all of which are in the Vatican Library. His last book, which Gabriel said was his greatest, was “The Virgin Mary In The Writings of Maria Valtorta”.”
