Are there any known Catholic authors who have tried to interpret the papal reigns of Pope Benedict XVI and Pope Francis as being a single reign in order to make both of them fit into St Malachy's Gloria oliviae of his Prophecy of the Popes?
The answer is YES. The papal reigns of Pope Benedict XVI and Pope Francis was understood as a single reign, it is called "expanded Petrine Ministry".
Are there any known Catholic authors who have tried to interpret it this way? I think there was a book already released and it's author is an italian journalist.
The Secret of Benedict XVI: Is He Still the Pope?
ANTONIO SOCCI, a native of Siena, is an Italian journalist and the director of the Perugia School of Journalism. His most recent books from Rizzoli are The Final Prophecy (2016), The House of Young Heroes (2017), and Betrayed, Subjected, Invaded (2018).
The Connection to Fatima and St.Malachi prophecy:
Socci concludes his work with Part Three, entitled “Fatima and the Last Pope.” He draws on his prior extensive study of the message of Fatima, seeing it as a key to understanding the present moment in the Church, and reminding his readers that the message of Fatima emphasized the strong link between the intercession of the Mother of God and the protection of the pope. At the center of the vision of Fatima, there are two persons: “the ‘bishop dressed in white’ and an old pope,” and Socci ponders whether perhaps this vision could refer to the present situation, noting that on May 21, 2017, while visiting Fatima, Pope Francis called himself “the bishop dressed in white.” Socci sees in Benedict a figure similar to the pope in the children’s vision: “half tremulous, with faltering steps, afflicted with pain and sorrow, crossing a large, half-ruined city” (p. 182). Socci undertakes a detailed examination of overlooked words of the children of Fatima, stating that the Blessed Virgin told them that if humanity did not do penance and convert, what would happen was “the end of the world” (p. 195). Sister Lucia declared in an interview in 1957 that “Russia will be the instrument chosen by God to punish the whole world, if we do not first obtain the conversion of that wretched nation” (p. 198). Implicit in Socci’s analysis and reflection is the sense that the outcome of the present crisis is of the utmost importance for the fate not only of the entire Church, but also of the entire world.
Socci’s final observation is that the medieval “Prophecy of Malachy,” which proposed to give a mysterious title to each future pope, ends with Benedict XVI. After this pope, it mysteriously says that there follows “the final persecution of the Holy Roman Church” and the figure of “Peter the Roman.” When asked in 2016 whether this prophecy could mean he is “the last one to represent the figure of the pope as we have known him up until now,” Benedict mysteriously replied, “Tutto può essere [Everything can be].” Further asked if this means he would be seen as the last pope of the old world or the first pope of the new world, Benedict replied, “I would say both. I do not belong anymore to the old world, but the new one in reality has not yet begun” (p. 213). Socci understands these astonishing comments to mean that both the world and the Church are on the cusp of epochal upheavals, inviting his readers to further reflection on the various prophecies in Scripture of the destruction of the Temple and on paragraphs 675-677 of the Catechism of the Catholic Church regarding the final trial of the Church. -
In New Book, Antonio Socci Speculates on the “Secret of Benedict XVI”
But if there is one person who can shed light on the expanded petrine ministry, he is none other than the secretary of Pope Benedict XVI, his name is Archbishop Georg Gänswein. Why? If there is a person that would know or familiar with the mind & heart of Pope Benedict XVI it would be his secretary.
Archbishop Gänswein: Benedict XVI Sees Resignation as Expanding Petrine Ministry
Speaking at the presentation of a new book on Benedict’s pontificate at the Pontifical Gregorian University in Rome May 20, Archbishop Gänswein also said that Pope Francis and Benedict are not two popes “in competition” with one another, but represent one “expanded” Petrine Office with “an active member” and a “contemplative.”
Archbishop Gänswein, who doubles as the personal secretary of the Pope Emeritus and prefect of the Pontifical Household, said Benedict did not abandon the papacy like Pope Celestine V in the 13th century but rather sought to continue his Petrine Office in a more appropriate way given his frailty.
“Therefore, from 11 February 2013, the papal ministry is not the same as before,” he said. “It is and remains the foundation of the Catholic Church; and yet it is a foundation that Benedict XVI has profoundly and lastingly transformed during his exceptional pontificate.”*
He further stated the following reflections;
But in his speech, Gänswein insisted "it was fitting" for Benedict to resign because he "was aware that the necessary strength for such a very heavy office was lessening. He could do it [resign], because he had long thought through, from a theological point of view, the possibility of a pope emeritus in the future. So he did it.”
Drawing on the Latin words “munus petrinum” — “Petrine ministry” — Gänswein pointed out the word “munus” has many meanings such as “service, duty, guide or gift”. He said that “before and after his resignation” Benedict has viewed his task as “participation in such a ‘Petrine ministry’.
“He left the Papal Throne and yet, with the step he took on 11 February 2013, he has not abandoned this ministry,” Gänswein explained, something "quite impossible after his irrevocable acceptance of the office in April 2005.“
Instead, he said, "he has built a personal office with a collegial and synodal dimension, almost a communal ministry, as if he had wanted to reiterate once again the invitation contained in the motto that the then-Joseph Ratzinger had as Archbishop of Munich and Freising and naturally maintained as Bishop of Rome: "cooperatores veritatis", which means ‘co-workers of the truth’.”
Archbishop Gänswein: Benedict XVI Sees Resignation as Expanding Petrine Ministry
But what is the significance of Pope Benedict XVI symbol gloria olivae and Pope Francis choosing the name of St.Francis as both of this symbolizes and represents Peace?
The significance of the symbol is connected to Our Lady of Fatima who is calling for Peace and it will end up in Medjugorje the Our Lady Queen of Peace.
The Call to Peace: the heart of the message of Our Lady of Fatima
Our Lady of Medjugorje (Croatian: Međugorska Gospa; also called Queen of Peace and Mother of the Redeemer) is the title given to the Blessed Virgin Mary by those who believe that she appeared in 1981 to six Herzegovinian teenagers in Medjugorje, Bosnia and Herzegovina (at the time in SFR Yugoslavia). Local Diocese as well as the Catholic Church have not recognised the apparitions as either supernatural or authentic.
...On May 13, 2017, a papal response came when Pope Francis declared that the original visions reported by the teenagers are worth studying in more depth, while the subsequent continued visions over the years are, in his view, of dubious value. - Our Lady of Medjugorje
The Two Great Popes reigning as one in our era representing peace symbol and link to the two Great Marian apparition in the span of century imploring the praying of the holy rosary daily for peace in the whole world is the preparation for the Church before it can enter to the New Era of Peace.
