Early life: 1927–1951
The birth house of Joseph Aloisius Ratzinger in Marktl, Bavaria
Joseph Aloisius Ratzinger was born on 16 April, Holy Saturday, 1927, at Schulstraße 11, at 8:30 in the morning in his parents' home in Marktl, Bavaria, Germany. He was baptised the same day. He is the third and youngest child of Joseph Ratzinger Sr., a police officer, and Maria Ratzinger (née Peintner); his grand-uncle was the German priest-politician Georg Ratzinger. His mother's family was originally from South Tyrol (now in Italy). Pope Benedict's elder brother, Georg Ratzinger, is a Catholic priest and is the former director of the Regensburger Domspatzen choir. His sister, Maria Ratzinger, who never married, managed Cardinal Ratzinger's household until her death in 1991.
At the age of five, Ratzinger was in a group of children who welcomed the visiting Cardinal Archbishop of Munich, Michael von Faulhaber, with flowers. Struck by the cardinal's distinctive garb, he announced later that day that he wanted to be a cardinal. He attended the elementary school in Aschau am Inn, which was renamed in his honour in 2009.
Ratzinger's family, especially his father, bitterly resented the Nazis, and his father's opposition to Nazism resulted in demotions and harassment of the family. Following his 14th birthday in 1941, Ratzinger was conscripted into the Hitler Youth—as membership was required by law for all 14-year-old German boys after March 1939—but was an unenthusiastic member who refused to attend meetings, according to his brother. In 1941, one of Ratzinger's cousins, a 14-year-old boy with Down syndrome, was taken away by the Nazi regime and murdered during the Action T4 campaign of Nazi eugenics. In 1943, while still in seminary, he was drafted into the German anti-aircraft corps as Luftwaffenhelfer. Ratzinger then trained in the German infantry. As the Allied front drew closer to his post in 1945, he deserted back to his family's home in Traunstein after his unit had ceased to exist, just as American troops established a headquarters in the Ratzinger household. As a German soldier, he was interned in a prisoner of war camp, but released a few months later at the end of the war in May 1945.
Ratzinger and his brother Georg entered Saint Michael Seminary in Traunstein in November 1945, later studying at the Ducal Georgianum (Herzogliches Georgianum) of the Ludwig-Maximilian University in Munich. They were both ordained in Freising on 29 June 1951 by Cardinal Michael von Faulhaber of Munich. Ratzinger recalled: "at the moment the elderly Archbishop laid his hands on me, a little bird – perhaps a lark – flew up from the altar in the high cathedral and trilled a little joyful song."
Ratzinger's 1953 dissertation was on St. Augustine and was titled The People and the House of God in Augustine's Doctrine of the Church. His habilitation (which qualified him for a professorship) was on Bonaventure. It was completed in 1957 and he became a professor of Freising College in 1958.
Encounter with Romano Guardini
In his early twenties, he was deeply influenced by the thought of Italian German Romano Guardini who taught in Munich 1946 to 1951 when Ratzinger was studying in Freising and later at the University of Munich. The intellectual affinity between these two thinkers, who would later become decisive figures for the twentieth-century Church, was preoccupied with rediscovering the essential in Christianity. Guardini with his 1938 tome "The Essence of Christianity," while Ratzinger penned "Introduction to Christianity," three decades later in 1968. Guardini inspired many in the Catholic social-democratic tradition, particularly the Communion and Liberation movement in the New Evangelization encouraged under the papacy of Polish Pope John Paul II. At the close of the twentieth the future Cardinal Ratzinger would write an introduction to a 1996 reissue of Guardini's 1954 classic "The Lord".
