Pope Benedict XVI, who on Monday announced his intention to resign this month, will be remembered as a staunch defender of Roman Catholic orthodoxy, a diehard traditionalist and a lightning rod for controversy. The German intellectual succeeded the long-reigning and popular John Paul II in April 2005 aged 78 after serving nearly a quarter-century as the Church’s doctrinal enforcer, earning himself the nickname “God’s Rottweiler.” The 85-year-old, who blamed his age for preventing him from continuing at the head of the papacy, will be the first pope to do so in centuries. “I have had to recognise my incapacity to adequately fulfill the ministry entrusted to me,” the head of the world’s 1.2 billion Catholics said as he would step down on February 28. Cardinal Joseph Ratzinger’s hardline approach, his nationality and his age were all seen as handicaps to his becoming pope, and Benedict had famously said in a 2010 interview that he would resign if he felt he could no longer carry out his papal duties. As head of the Congregation for the Doctrine of the Faith and then as pope, he rejected the ordination of women and marriage for priests. He opposed homosexuality and communism and was never afraid of upsetting political sensibilities. In 1984, he said “communist regimes which came to power in the name of the liberation are one of the disgraces of our times.” Ratzinger has also attacked rock music, calling it “the expression of basic passions”. As pope, Benedict championed Christianity’s European roots and showed his conservatism by repeatedly stressing family values and fiercely opposing abortion, euthanasia and gay marriage. He also reintroduced the long-discarded Latin mass under certain conditions. Above all, Benedict will be remembered for a disastrous public relations record that got him into hot water with Muslims, Jews, gays, native Indians, Poles, AIDS activists and even scientists. Memories are still fresh of the fury the German pope unleashed in the Muslim world with a speech in September 2006 in which he appeared to endorse the view of an obscure 14th-century Byzantine emperor that Islam is inherently violent. The academic lecture sparked violent protests in several countries as well as attacks on Christian targets. In 2009, the pope struggled to mollify Jews after he invited a breakaway ultra-conservative faction back into the fold of the Roman Catholic Church by lifting the excommunication of four bishops, including one who insists that no one died in Nazi gas chambers. Just weeks later Benedict added Aids activists to the list of groups he has angered. On a trip to Africa, the region hardest hit by the Aids pandemic, he said that condom use could be aggravating the crisis. Born on April 16, 1927, in Marktl am Inn, in the predominantly Catholic southern German region of Bavaria, he was the son of a policeman. Ratzinger gravitated gradually towards the priesthood, entering a seminary in 1939, the same year he was required to join the Hitler Youth movement. He was ordained priest at the same time as his older brother Georg in 1951, and began teaching theology at Freising College in 1958. Ratzinger went on from there to teach at several other German universities, notably in Bonn, Meunster and Regensburg. The brilliant scholar caught the eye of Cologne Archbishop Joseph Frings, a cardinal who brought him to Rome to work as an advisor to the Second Vatican Council, hammering out modernisation reforms from 1962 to 1965. Pope Paul VI named Ratzinger archbishop of Munich in 1977 and made him a cardinal the same year. The four-year stint in Munich was his only real pastoral experience before he became pope. It was during the 1978 conclave of cardinals to elect a successor to Paul VI that Ratzinger got to know Karol Wojtyla, the future John Paul II. Three years later he agreed to head the Vatican’s doctrinal congregation. One of his first moves was to spearhead opposition to liberation theology, the movement with Marxist overtones that swept Latin America in the 1970s. It focuses on Christ as the liberator of the oppressed and emphasises the Christian mission of bringing justice to the poor and oppressed, particularly through political activism. A quiet, almost shy person, Benedict never succeeded in generating the fervour enjoyed by John Paul II. Instead, he shunned rock star status, once describing himself as “just the vicar” at the Roman Catholic Church’s periodic World Youth Days. The Polish pope was greeted with enthusiasm bordering on hysteria at these events, and he did little to dampen down the adulation, to the consternation of some in the Church hierarchy. The intellectual Benedict, an accomplished pianist, was a prolific writer. Apart from three encyclicals, or instructions to the Roman Catholic flock, he wrote around 40 other works including a best-seller, “Jesus of Nazareth,” that contested political interpretations of Christ’s role. Popes who have stepped down At most, there have been only five papal abdications in 2,000 years, but numerous popes were deposed or exiled, 21 popes are listed as martyrs and nine others are considered martyrs. Four popes died in exile or in prison, six were assassinated, two died of wounds received in the course of riots and one was killed when a roof collapsed. Here are some examples of previous popes who have given up the papacy: * In 1045, Benedict IX, renowned as one of the most disgraceful popes the Church has known, sold his papacy to his godfather, pious priest John Gratian, so that he could get married. Reportedly unable to persuade the woman in question to have him, he returned to seize Rome. * In 1046, Gratian, who had reigned shortly as pope Gregory VI and was considered the true pope by many despite Benedict IX’s violent return to claim the throne, was forced to resign himself amid accusations he had bought the papacy. * In 1294, Celestine V, a simple hermit who was elected to end a deadlock among cardinals, proved incompetent and stepped down after reigning a mere five months. He had issued a decree declaring it possible for a pope to resign, opening up the way for his own departure. * In 1415, Gregory XII resigned in a bid to end the “Western Schism”, when two rival claimants declared themselves pope in Pisa and Avignon and threatened to tear apart Roman Catholicism. * In 1804, Pius VII signed an abdication of the papal throne before setting out for Paris to crown Napoleon to be put into effect in case he were imprisoned in France. During the second world war, Pius XII is reported to have signed a document which said that he was to be considered as having resigned his office should he be kidnapped by the Nazis. Several popes were resigned or martyred as the Roman Empire collapsed, and the Eternal City – sacked and depopulated by barbarian hordes – fell prey to quarrelling factions. But the historical details of how they fell are often lost in the mist of time, and often only the legends remain.
