Question: On what day was the describer of the Anglican church as "our beloved sister Church" born?

full_context: Document 1: 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 2: Pope Paul VI: This was a significant step towards restoring communion between Rome and Constantinople. It produced the Catholic-Orthodox Joint declaration of 1965, which was read out on 7 December 1965, simultaneously at a public meeting of the Second Vatican Council in Rome and at a special ceremony in Istanbul. The declaration did not end the schism, but showed a desire for greater reconciliation between the two churches. In May 1973, the Coptic Patriarch Shenouda III of Alexandria visited the Vatican, where he met three times with Pope Paul VI. A common declaration and a joint Creed issued after the visit demonstrated that there are virtually no more[additional citation needed] theological discrepancies between the Coptic and Roman Catholic Churches.
Document 3: Pope Paul VI: Paul VI opened the third period on 14 September 1964, telling the Council Fathers that he viewed the text about the Church as the most important document to come out from the Council. As the Council discussed the role of bishops in the papacy, Paul VI issued an explanatory note confirming the primacy of the papacy, a step which was viewed by some as meddling in the affairs of the Council American bishops pushed for a speedy resolution on religious freedom, but Paul VI insisted this to be approved together with related texts such as ecumenism. The Pope concluded the session on 21 November 1964, with the formal pronouncement of Mary as Mother of the Church.
Document 4: 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 5: Pope Paul VI: Cardinal Augustin Bea, the head of the Secretariat for Promoting Christian Unity, added at the end of the visit, "Let us move forward in Christ. God wants it. Humanity is waiting for it." Unmoved by a harsh condemnation by the Congregation of Faith on mixed marriages precisely at this time of the visit, Paul VI and Ramsey appointed a preparatory commission which was to put the common agenda into practice on such issues as mixed marriages. This resulted in a joint Malta declaration, the first joint agreement on the Creed since the Reformation. Paul VI was a good friend of the Anglican Church, which he described as "our beloved sister Church". This description was unique to Paul and not used by later popes.
Document 6: Pope Paul VI: Ecclesiam suam was given at St. Peter's, Rome, on the Feast of the Transfiguration, 6 August 1964, the second year of his Pontificate. It is considered an important document, identifying the Catholic Church with the Body of Christ. A later Council document Lumen Gentium stated that the Church subsists in the Body of Christ, raising questions as to the difference between "is" and "subsists in". Paul VI appealed to "all people of good will" and discussed necessary dialogues within the Church and between the Churches and with atheism.
Document 7: 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 8: 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 9: 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 10: 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 11: 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 12: 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 13: 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 14: 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 15: 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.
