Walter Brandmüller (born 5 January 1929) is a German prelate of the Catholic Church, a cardinal since 2010. He was president of the Pontifical Committee for Historical Sciences from 1998 to 2009.
Brandmüller was born in 1929 in Ansbach, Germany. His father was Catholic and his mother was Protestant. Brandmüller was baptized as a Protestant and converted to Catholicism from Lutheranism[1] in his adolescence.[2] [3] He studied at the Ludwig-Maximilians University in Munich in 1963, he earned a doctorate in history (doctoral thesis: "Das Wiedererstehen katholischer Gemeinden in den Fürstentümern Ansbach und Bayreuth", 'The reestablishment of Catholic parishes in the principalities of Ansbach and Bayreuth'); and he obtained the "habilitation" in 1967 with the dissertation "Das Konzil von Pavia-Siena (1423–1424)" ('The council of Pavia-Siena').
On 26 July 1953, he was ordained a priest in Bamberg by Joseph Otto Kolb, Archbishop of Bamberg. He did pastoral work in the church of Saint John, Kronach, 1953–1957, and in that of Saint Martin, Bamberg, 1957–1960. Thereafter he did further studies in Munich. He served as Professor of Church History and Patrology at the University of Dillingen from 30 October 1969 until 1971. From 7 October 1970 until his retirement in 1997 he was Professor of Modern and Medieval Church History at the University of Augsburg. From 1971 until 1998, he was parish priest of the Assumption, Walleshausen, Diocese of Augsburg.
A specialist in the history of the councils, he is founder and editor of the journal Annuarium conciliorum historiae (Paderborn, 1969); and of the series "Konziliengeschichte" (1979), which has published 37 volumes so far. He also published the "Handbook of Bavarian Church History" (St. Ottilie, 1991–1999, 3 vols. in 4). From 1981 to 1998, he was a member of the Pontifical Committee for Historical Sciences. He was appointed Honorary Prelate on 17 July 1983. On 22 July 1990, he received the Cross of the Order of Merit of the Federal Republic of Germany from president Richard von Weizsäcker. He served as President of the International Commission for Contemporary Church History from 1998 until 2006. He has been a canon of the chapter of the Saint Peter's Basilica since 1997. From 13 June 1998 until 3 December 2009, he was President of the Pontifical Committee for Historical Sciences.
On 20 November 2010 Pope Benedict XVI elevated Brandmüller to the College of Cardinals as Cardinal-Deacon of S. Giuliano dei Fiamminghi.[4] Before being made a cardinal, as required by canon law,[5] he received episcopal consecration on 13 November from Cardinal Raffaele Farina, Archivist and Librarian of the Holy Roman Church, assisted by Ludwig Schick, Archbishop of Bamberg and Giuseppe De Andrea.
In September 2016, Brandmüller, along with Cardinals Carlo Caffarra, Raymond Burke and Joachim Meisner, submitted to Pope Francis a private letter with five dubia (questions) seeking clarification on various points of doctrine in the Pope's apostolic exhortation Amoris laetitia. The first dubium concerned the reception of the sacraments by the divorced and remarried; the other four asked about fundamental issues of the Christian life, and referenced Pope John Paul II's encyclical Veritatis splendor. In November 2016, having not received a response, they publicised their letter, entitled "Seeking Clarity: A Plea to Untie the Knots in Amoris Laetitia".[6]
In May 2017, Caffarra, Brandmüller, Burke and Meisner sent a private letter dated 25 April and hand-delivered to the Pope on 6 May asking for an audience, having received no response to the dubia they had earlier sent him in September 2016. Having received no response, they made their letter public in June 2017.[7] Two cardinals later died that year: Meisner on 5 July;[8] and Caffara on 6 September.[9]
In February 2019, Brandmüller and Burke penned an open letter addressed to Pope Francis calling for an end of "the plague of the homosexual agenda", which they blamed for the sexual abuse crisis engulfing the Catholic Church. They claimed the agenda was spread by "organized networks" protected by a "conspiracy of silence".[10] After ten years at the rank of cardinal deacon, he exercised his option to assume the rank of cardinal priest, which Pope Francis confirmed on 3 May 2021.[11]
In August 2023, Brandmüller, along with Cardinals Burke, Íñiguez, Sarah, and Zen, submitted another list of five dubia to Pope Francis related to the upcoming Synod on Synodality. The dubia questioned the necessity of the upcoming synod, asked whether the blessing of same-sex unions was theologically admissible, and questioned the Pope's claim that "forgiveness is a human right".[12]
