Question: What was the first name of the person whose liturgical feast is celebrated on September 26th at birth?

full_context: Document 1: Pope Paul VI: As war broke out, Maglione, Tardini and Montini were the main figures in the Vatican's State Department, as despatches originated from or addressed to them during the war years.[page needed] Montini was in charge of taking care of the "ordinary affairs" of the Secretariat of State, which took much of the mornings of every working day. In the afternoon he moved to the third floor into the Office of the Private Secretary of the Pontiff. Pius XII did not have a personal secretary. As did several popes before him, he delegated the secretarial functions to the State Secretariat. During the war years, thousands of letters from all parts of the world arrived at the desk of the pope, most of them asking for understanding, prayer and help. Montini was tasked to formulate the replies in the name of Pius XII, expressing his empathy, and understanding and providing help, where possible.
Document 2: Pope Paul VI: On 24 April 2014, it was reported in the Italian magazine Credere that the late pope could possibly be beatified on 19 October 2014. This report from the magazine further stated that several cardinals and bishops would meet on 5 May to confirm the miracle that had previously been approved, and then present it to Pope Francis who may sign the decree for beatification shortly after that. The Congregation for the Causes of Saints held that meeting and positively concluded that the healing was indeed a miracle that could be attributed to the late pope. The matter shall now soon be presented to the pope for approval.
Document 3: Pope John XXIII: Far from being a mere "stopgap" pope, to great excitement, John XXIII called for an ecumenical council fewer than ninety years after the First Vatican Council (Vatican I's predecessor, the Council of Trent, had been held in the 16th century). This decision was announced on 29 January 1959 at the Basilica of Saint Paul Outside the Walls. Cardinal Giovanni Battista Montini, who later became Pope Paul VI, remarked to Giulio Bevilacqua that "this holy old boy doesn't realise what a hornet's nest he's stirring up". From the Second Vatican Council came changes that reshaped the face of Catholicism: a comprehensively revised liturgy, a stronger emphasis on ecumenism, and a new approach to the world.
Document 4: Pope John XXIII: The Roman Catholic Church celebrates his feast day not on the date of his death, June 3, as is usual, nor even on the day of his papal inauguration (as is sometimes done with Popes who are Saints, such as with John Paul II) but on 11 October, the day of the first session of the Second Vatican Council. This is understandable, since he was the one who had had the idea for it and had convened it. On Thursday, 11 September 2014, Pope Francis added his optional memorial to the worldwide General Roman Calendar of saints' feast days, in response to global requests. He is commemorated on the date of his death, 3 June, by the Evangelical Lutheran Church in America and on the following day, 4 June, by the Anglican Church of Canada and the Episcopal Church (United States).
Document 5: Pope Paul VI: With the six consistories, Paul VI continued the internationalization policies started by Pius XII in 1946 and continued by John XXIII. In his 1976 consistory, five of twenty cardinals originated from Africa, one of them a son of a tribal chief with fifty wives. Several prominent Latin Americans like Eduardo Francisco Pironio of Argentina; Luis Aponte Martinez of Puerto Rico and Eugênio de Araújo Sales and Aloisio Lorscheider from Brazil were also elevated by him. There were voices within the Church at the time saying that the European period of the Church was coming to a close, a view shared by Britain's Cardinal Basil Hume. At the same time, the members of the College of Cardinals lost some of their previous influences, after Paul VI decreed, that not only cardinals but also bishops too may participate in committees of the Roman Curia. The age limit of eighty years imposed by the Pope, a numerical increase of Cardinals by almost 100%, and a reform of the regal vestments of the "Princes of the Church" further contributed to a service-oriented perception of Cardinals under his pontificate. The increased number of Cardinals from the Third World and the papal emphasis on related issues was nevertheless welcomed by many in Western Europe.
Document 6: Pope Paul VI: During his period in Milan, Montini was known as a progressive member of the Catholic hierarchy. Montini went new ways in pastoral care, which he reformed. He used his authority to ensure that the liturgical reforms of Pius XII were carried out at the local level and employed innovative methods to reach the people of Milan: Huge posters announced that 1,000 voices would speak to them from 10 to 24 November 1957. More than 500 priests and many bishops, cardinals and lay persons delivered 7,000 sermons in the period not only in churches but in factories, meeting halls, houses, courtyards, schools, offices, military barracks, hospitals, hotels and other places, where people meet. His goal was the re-introduction of faith to a city without much religion. "If only we can say Our Father and know what this means, then we would understand the Christian faith."
Document 7: Pope Paul VI: In December 2013, Vatican officials approved a supposed miracle that was attributed to the intercession of the late pontiff which was the curing of an unborn child in California, U.S.A in the 1990s. It was expected that Pope Francis would approve the miracle in the near future, thus, warranting the beatification of the late pontiff. In February 2014, it was reported that the consulting Vatican theologians to the Congregation for the Causes of Saints recognized the miracle attributed to the late pontiff.
Document 8: Pope Paul VI: Pius XII delivered an address about Montini's appointment from his sick-bed over radio to those assembled in St. Peter's Basilica on 12 December 1954. Both Montini and the pope had tears in their eyes when Montini parted for his dioceses with 1,000 churches, 2,500 priests and 3,500,000 souls. On 5 January 1955, Montini formally took possession of his Cathedral of Milan. Montini, after a period of preparation, liked his new tasks as archbishop, connecting to all groups of faithful in Milan. He enjoyed meetings with intellectuals, artists and writers.
Document 9: Pope Paul VI: After his election as Bishop of Rome, Paul VI first met with the priests in his new dioceses. He told them that in Milan he started a dialogue with the modern world and asked them to seek contact with all people from all walks of life. Six days after his election he announced that he would continue Vatican II and convened the opening to take place on 29 September 1963. In a radio address to the world, Paul VI recalled the uniqueness of his predecessors, the strength of Pius XI, the wisdom and intelligence of Pius XII and the love of John XXIII. As "his pontifical goals" he mentioned the continuation and completion of Vatican II, the reform of the Canon Law and improved social peace and justice in the world. The Unity of Christianity would be central to his activities.
Document 10: Pope Paul VI: Paul VI did renounce many traditional symbols of the papacy and the Catholic Church; some of his changes to the papal dress were reversed by Pope Benedict XVI in the early 21st century. Refusing a Vatican army of colourful military uniforms from centuries, he got rid of them. He became the first pope to visit five continents. Paul VI systematically continued and completed the efforts of his predecessors, to turn the Euro-centric Church into a Church of the world, by integrating the bishops from all continents in its government and in the Synods which he convened. His 6 August 1967 motu proprio Pro Comperto Sane opened the Roman Curia to the bishops of the world. Until then, only Cardinals could be leading members of the Curia.
Document 11: Pope John XXIII: The 50th anniversary of his death was celebrated on 3 June 2013 by Pope Francis, who visited his tomb and prayed there, then addressing the gathered crowd and spoke about the late pope. The people that gathered there at the tomb were from Bergamo, the province where the late pope came from. A month later, on 5 July 2013, Francis approved Pope John XXIII for canonization, along with Pope John Paul II without the traditional second miracle required. Instead, Francis based this decision on John XXIII's merits for the Second Vatican Council. On Sunday, 27 April 2014, John XXIII and Pope John Paul II were declared saints on Divine Mercy Sunday.
Document 12: Pope Paul VI: On 20 December 2012, Pope Benedict XVI, in an audience with the Cardinal Prefect of the Congregation for the Causes of Saints, declared that the late pontiff had lived a life of heroic virtue, which means that he could be called "Venerable". A miracle attributed to the intercession of Paul VI was approved on 9 May 2014 by Pope Francis. The beatification ceremony for Paul VI was held on 19 October 2014, which means that he can now be called "Blessed". His liturgical feast day is celebrated on the date of his birth, 26 September, rather than the day of his death as is usual.
Document 13: Pope Paul VI: Pope Paul VI (Latin: Paulus VI; Italian: Paolo VI), born Giovanni Battista Enrico Antonio Maria Montini (Italian pronunciation: [dʒioˈvani baˈtista enˈriko anˈtonjo marˈija monˈtini]; 26 September 1897 – 6 August 1978), reigned as Pope from 21 June 1963 to his death in 1978. Succeeding Pope John XXIII, he continued the Second Vatican Council which he closed in 1965, implementing its numerous reforms, and fostered improved ecumenical relations with Eastern Orthodox and Protestants, which resulted in many historic meetings and agreements. Montini served in the Vatican's Secretariat of State from 1922 to 1954. While in the Secretariat of State, Montini and Domenico Tardini were considered as the closest and most influential colleagues of Pope Pius XII, who in 1954 named him Archbishop of Milan, the largest Italian diocese. Montini automatically became the Secretary of the Italian Bishops Conference. John XXIII elevated him to the College of Cardinals in 1958, and after the death of John XXIII, Montini was considered one of his most likely successors.
Document 14: Pope Paul VI: Paul VI supported the new-found harmony and cooperation with Protestants on so many levels. When Cardinal Augustin Bea went to see him for permission for a joint Catholic-Protestant translation of the Bible with Protestant Bible societies, the pope walked towards him and exclaimed, "as far as the cooperation with Bible societies is concerned, I am totally in favour." He issued a formal approval on Pentecost 1967, the feast on which the Holy Spirit descended on the Christians, overcoming all linguistic difficulties, according to Christian tradition.
Document 15: Pope Paul VI: Paul VI revolutionized papal elections by ordering that only cardinals below the age of eighty might participate in future conclaves. In Ecclesiae Sanctae, his motu proprio of 6 August 1966, he further invited all bishops to offer their retirement to the pontiff no later than the completion of their 75th year of age. This requirement was extended to all Cardinals of the Catholic Church on 21 November 1970. With these two stipulations, the Pope filled several positions with younger bishops and cardinals, and further internationalized the Roman Curia in light of several resignations due to age.
