EIGHT YEARS AS POPE CAPPED LONG MINISTRY AS TEACHER OF THE FAITH

He died Dec. 31 at the age of 95, nearly 10 years after leaving the papacy to retire to what he said would be a life of prayer and study.

A close collaborator of St. John Paul II and the theological expert behind many of his major teachings and gestures, Pope Benedict came to the papacy after 24 years heading the doctrinal congregation's work of safeguarding Catholic teaching on faith and morals, correcting the work of some Catholic theologians and ensuring the theological solidity of the documents issued by other Vatican offices.

As pope, he continued writing as a theologian, but also made historically important gestures to Catholics who had difficulty accepting all of the teachings of the Second Vatican Council, particularly about the liturgy. In 2007, he widened permission to use the "extraordinary" or pre-Vatican II form of the Mass and, a short time later, extended a hand to the traditionalist Society of St. Pius X. Besides lifting the excommunications of four of the society's bishops who were ordained illicitly in 1988, he launched a long and intense dialogue with the group. In the end, though, the talks broke down.

His papacy, which began when he was 78, was extremely busy for a man who already had a pacemaker and who had wanted to retire to study, write and pray when he turned 75. He used virtually every medium at his disposal -- books and Twitter, sermons and encyclicals -- to catechize the faithful on the foundational beliefs and practices of Christianity, ranging from the sermons of St. Augustine to the sign of the cross.

Pope Benedict was the first pope to meet with victims of clerical sexual abuse. He clarified church laws to expedite cases and mandated that bishops' conferences put in place stringent norms against abuse.

Although he did not expect to travel much, he ended up making 24 trips to six continents and three times presided over World Youth Day mega-gatherings: in Germany in 2005, Australia in 2008, and Spain in 2011.

On a historic visit to the United States in 2008, the pope brought his own identity into clearer focus for Americans. He set forth a moral challenge on issues ranging from economic justice to abortion. He also took church recognition of the priestly sex-abuse scandal to a new level, expressing his personal shame at what happened and personally praying with victims.

While still in his 30s, he served as an influential adviser during the Second Vatican Council, 1962-65, and as pope, he made it a priority to correct what he saw as overly expansive interpretations of Vatican II in favor of readings that stressed the council's continuity with the church's millennial traditions.

Under his oversight, the Vatican continued to highlight the church's moral boundaries on issues such as end-of-life medical care, marriage and homosexuality. But the pope's message to society at large focused less on single issues and more on the risk of losing the basic relationship between the human being and the Creator.

Surprising those who had expected a by-the-book pontificate from a man who had spent so many years as the Vatican's chief doctrinal official, Pope Benedict emphasized that Christianity was a religion of love and not a religion of rules.

The German-born pontiff did not try to match the popularity of St. John Paul, but the millions of people who came to see him in Rome and abroad came to appreciate his smile, his frequent ad-libs and his ability to speak from the heart.

Some of Pope Benedict's most memorable statements came when he applied simple Gospel values to social issues such as the protection of human life, the environment and economics. When the global financial crisis worsened in 2008, for example, the pope insisted that financial institutions must put people before profits. He also reminded people that money and worldly success are passing realities, saying: "Whoever builds his life on these things -- on material things, on success, on appearances -- is building on sand."

He consistently warned the West that unless its secularized society rediscovered religious values, it could not hope to engage in real dialogue with Muslims and members of other religious traditions.

In his encyclicals and in his books on "Jesus of Nazareth," the pope honed that message, asking readers to discover the essential connections between sacrificial love, works of charity, a dedication to the truth and the Gospel of Christ.

The retired pope looked in-depth at his papacy and resignation, his relationships with St. John Paul and Pope Francis and a host of other issues in "Last Testament," a book-length interview with journalist Peter Seewald published in 2016.

In the book, Pope Benedict insisted once again that he was not pressured by anyone or any event to resign and he did not feel he was running away from any problem. However, he acknowledged "practical governance was not my forte, and this certainly was a weakness."

Insisting "my hour had passed, and I had given all I could," Pope Benedict said he never regretted resigning, but he did regret hurting friends and faithful who were "really distressed and felt forsaken" by his stepping down.

Less than a month after resigning, he already looked frailer and walked with noticeably more difficulty than he did when he left office. The video images released by the Vatican March 23, 2013, when his successor, Pope Francis, visited him at Castel Gandolfo underscored the "diminishing energy" Pope Benedict had said led to his resignation.

Pope Benedict moved to the papal summer villa at Castel Gandolfo Feb. 28, 2013, the day his resignation took effect. He remained at the villa south of Rome for two months -- a period that included the conclave that elected Pope Francis as his successor and the first month of the new pope's pontificate. The retired pope moved back to the Vatican May 2, 2013, living in a monastery remodeled as a residence for him, his secretary and the consecrated women who cared for his household before and after his resignation.

On his only post-retirement trip outside of Italy, he flew to Germany in June 2020 for a five-day visit with his ailing 96-year-old brother.

Answering questions from reporters on a flight back from Brazil in July 2013, Pope Francis spoke with admiration of the retired pope's humility, intelligence and prayerfulness. The unusual situation of having a pope and a retired pope both living at the Vatican was working out very well, Pope Francis said. Having the retired pope nearby to consult with, or ask questions of, Pope Francis said, was "like having a grandfather at home -- a very wise grandfather."

By the time Pope Benedict had been retired for a year, his daily routine was set. Archbishop Georg Ganswein, his personal secretary, said his days began with Mass, morning prayer and breakfast. Although mostly hidden from public view, he was not cloistered, but continued welcoming old friends and colleagues, engaging in dialogue or offering spiritual counsel. He spent hours reading and dealing with correspondence before a 4 p.m. stroll in the garden and recitation of the rosary.

In the early days of his retirement, to the delight and surprise of pilgrims and cardinals, Pope Benedict appeared at major events with Pope Francis, including the opening of the Holy Door of St. Peter's Basilica Dec. 8, 2015.

At a June 2016 celebration in the Apostolic Palace, where Pope Benedict once lived and worked, Pope Francis, top officials of the Roman Curia and a few friends gathered with him to mark the 65th anniversary of the retired pontiff's priestly ordination. Pope Francis told Pope Benedict that with him in residence, the monastery in the Vatican Gardens "emanates tranquility, peace, strength, faithfulness, maturity, faith, dedication and loyalty, which does so much good for me and gives strength to me and to the whole church."

Pope Benedict replied to Pope Francis, "More than the beauty found in the Vatican Gardens, your goodness is the place where I live; I feel protected."

He prayed that Pope Francis would continue to "lead us all on this path of divine mercy that shows the path of Jesus, to Jesus and to God."

Mercy was a prominent topic in an interview Pope Benedict gave in 2015. The Catholic focus on mercy really began with St. John Paul, the retired pope told Belgian Jesuit Father Jacques Servais in the written interview, which was not released until March 2016.

From his experience as a youth during World War II and his ministry under communism in Poland, St. John Paul "affirmed that mercy is the only true and ultimately effective reaction against the power of evil. Only where there is mercy does cruelty end, only there do evil and violence stop," said Pope Benedict, who worked closely with the Polish pope for decades.

"Pope Francis," he said, "is in complete agreement with this line. His pastoral practice is expressed precisely in the fact that he speaks continuously of God's mercy."

Pope Benedict had said he planned to live a "hidden life" in retirement -- and to a large extent he did. But when he did make contributions to public discussions, they became headline news. In April 2019, for instance, what he described as "notes" on the clerical sexual abuse crisis were published; and, in January 2020, an essay he wrote on priestly celibacy was published in a book by Cardinal Robert Sarah, prefect of the Congregation for Divine Worship and the Sacraments.

In the text on abuse, which the retired pope said was motivated by the February 2019 Vatican summit on the crisis, Pope Benedict traced the abuse crisis to a loss of certainty about faith and morals, especially beginning in the late 1960s. To address the crisis, he wrote, "what is required first and foremost is the renewal of the faith in the reality of Jesus Christ given to us in the Blessed Sacrament."

The 2020 text on celibacy became the center of a media storm, not only because of its content, but also because Catholics were awaiting Pope Francis' official response to the Synod of Bishops for the Amazon and suggestions made there that in remote areas the church could consider ordaining some married men to take the sacraments to Catholics who usually go months without.

Since marriage and priesthood both demand the total devotion and self-giving of a man to his vocation, "it does not seem possible to realize both vocations simultaneously," Pope Benedict wrote in his essay.

The retired pope's contribution to the discussion became even more controversial when Archbishop Ganswein informed media and the original publisher that while Pope Benedict contributed an essay to Cardinal Sarah's book, he did not want to be listed as co-author of the volume.

As inevitable as his election seemed after St. John Paul died in 2005, Pope Benedict's path to the papacy was long and indirect.

Joseph Ratzinger was born April 16, 1927, in the Bavarian town of Marktl am Inn, the third and youngest child of a police officer, Joseph Sr., and his wife, Maria. Young Joseph joined his brother, Georg, at a minor seminary in 1939.

Like other young students in Germany at the time, he was automatically enrolled in the Hitler Youth program, but soon stopped going to meetings. During World War II, he was conscripted into the army, and in the spring of 1945, he deserted his unit and returned home, spending a few months in an Allied prisoner-of-war camp. He returned to the seminary late in 1945 and was ordained six years later, along with his brother.

In a meeting with young people in 2006, the pope said witnessing the brutality of the Nazi regime helped persuade him to become a priest. But he also had to overcome some doubts, he said. For one thing, he asked himself whether he "could faithfully live celibacy" his entire life. He also recognized that his real leanings were toward theology and wondered whether he had the qualities of a good pastor and the ability "to be simple with the simple people."

After a short stint as a parish priest, the future pope began a teaching career and built a reputation as one of the church's foremost theologians. At Vatican II, he made important contributions as a theological expert and embraced the council's early work. But he began to have misgivings about an emerging anti-Roman bias, the idea of a "church from below" run on a parliamentary model, and the direction of theological research in the church -- criticism that would become even sharper in later years.

In a 2005 speech that served as a kind of manifesto for his young papacy, Pope Benedict rejected what he called a "hermeneutic of discontinuity and rupture" in interpreting Vatican II as a radical break with the past. The pope called instead for reading the council through a "hermeneutic of reform" in continuity with Catholic tradition.

In 1977, St. Paul VI named him archbishop of Munich and Freising and, four years later, Pope John Paul called him to head the Congregation for the Doctrine of the Faith, where he wielded great influence on issues such as liberation theology, dissent from church teachings and pressure for women's ordination. Serving in this role for nearly a quarter century, then-Cardinal Ratzinger earned a reputation in some quarters as a sort of grand inquisitor, seeking to stamp out independent thinking, an image belied by his passion for debate with thinkers inside and outside the church.

As the newly elected pope in 2005, he explained that he took the name Benedict to evoke the memory of Pope Benedict XV, a "courageous prophet of peace" during World War I, and said he wanted to place his ministry at the service of reconciliation and harmony among peoples.

Like his namesake and his predecessors, he was untiring in his appeals for an end to violence in world trouble spots and for dialogue as the only true and lasting solution to conflict. Another key to building a better world, he said repeatedly, is to respect the right of each person to seek and to worship God.

A direct appeal to China's communist government to respect the religious freedom of its people was a central part of Pope Benedict's 2007 Letter to Chinese Catholics. The letter also pleaded with the faithful on the mainland to work toward reconciliation between communities that had accepted some government control in order to minister openly and those that continued to practice their faith more clandestinely.

In the aftermath of the Sept. 11, 2001, terrorist attacks in the United States and amid reports of rising religious-inspired violence in various parts of the world, Pope Benedict also repeatedly and clearly condemned all violence committed in the name of God.

One of the biggest tests of his papacy came after a lecture at Germany's University of Regensburg, in 2006, when he quoted a Christian medieval emperor who said the prophet Muhammad had brought "things only evil and inhuman, such as his command to spread by the sword the faith he preached."

Protests in the Muslim world followed, and Pope Benedict apologized that his words had offended Muslims, distancing himself from the text he had quoted. Soon after, he accepted the invitation of an international group of Muslim scholars and leaders to launch a new dialogue initiative, "The Common Word," looking at teachings that Christians and Muslims share.
