The pope spoke Aug. 17 at Haemi Castle, about 60 miles south of Seoul, where thousands of Catholics were imprisoned and tortured during the 19th century, and at a nearby shrine commemorating those killed. It was the last full day of his visit to Korea, the first of his pontificate to Asia.
"On this vast continent which is home to a great variety of cultures, the church is called to be versatile and creative in her witness to the Gospel through dialogue and openness to all," Pope Francis told several hundred Asian bishops, leaders of the church in a region that is only 3 percent Catholic.
The pope then offered an example of his desired approach.
"In this spirit of openness to others, I earnestly hope that those countries of your continent with whom the Holy See does not yet enjoy a full relationship may not hesitate to further a dialogue for the benefit of all," the pope said.
His statement was most obviously an overture to China, which has not had formal relations with the Vatican since shortly after the country's 1949 communist revolution.
It was the latest of Pope Francis' several diplomatic gestures to Beijing since the start of his trip to Korea. During the papal flight from Rome Aug. 14, he sent a telegram of prayers and greetings to China's President Xi Jinping. Two days later, in a question-and-answer session with young people, the pope notably declined to answer a man from Hong Kong who asked how to help Catholics in China, where he said "control and oppression" were increasing as the church on the mainland grew.
China requires Catholic communities to register with the government-controlled Catholic Patriotic Association, which has ordained bishops without the approval of the pope, and Chinese authorities have frequently arrested Catholics who reject government control.
Speaking with reporters after the pope's speech, Jesuit Father Federico Lombardi, the Vatican spokesman, noted that the Vatican does not have diplomatic relations with several Asian countries, including North Korea, Vietnam, Myanmar, Laos, Brunei and Bhutan.
"This offer of the pope of dialogue is related to all these lands, and not just China, even if China is the biggest, as we know," Father Lombardi said.
In an off-the-cuff addition to his original text, Pope Francis evoked the attitude he hoped such countries would adopt to the church: "These Christians don't come as conquerors, they don't come to take away our identity. They bring us theirs, but want to travel with us."
"Some will ask for baptism, others will not, but we will always travel together," the pope said.
Fittingly, Pope Francis started the day by baptizing a Korean man, Lee Hojin, in a brief ceremony at the nunciature in Seoul where the pope has been staying.
Lee, whose son was among more than 300 people killed in the April sinking of the Sewol ferry, met the pope Aug. 15 along with other family members and survivors of the disaster. He told the pope he had been preparing for two years to become a Catholic and now wanted the pope to baptize him. Lee took the baptismal name of Francis.
The pope has shown special concern for the Sewol case; for three days in a row, in a remarkable departure from papal custom, he has worn a yellow-ribbon pin commemorating the victims.
Pope Francis told the Asian bishops that dialogue required "empathy and sincere receptivity," but also, as a "fundamental point of reference," a clear sense of "our identity as Christians."
"If we are to speak freely, openly and fruitfully with others, we must be clear about who we are, what God has done for us, and what it is that he asks of us," he said.
The pope said Christian identity is constantly tempted by the "spirit of the world" in a number of ways, including relativism, which leads people to "forget that in a world of rapid and disorienting change, there is much that is unchanging, much that has its ultimate foundation in Christ, who is the same yesterday and today and forever."
The pope returned to the theme of Christian identity, though without using the term, when he addressed more than 40,000 Asian Youth Day participants at the event's closing Mass later in the day.
"The Asian continent, imbued with rich philosophical and religious traditions, remains a great frontier for your testimony to Christ, the way, the truth and the life," he said. "You have a right and a duty to take full part in the life of your societies. Do not be afraid to bring the wisdom of faith to every aspect of social life.
"You see and love, from within, all that is beautiful, noble and true in your cultures and traditions. Yet as Christians, you also know that the Gospel has the power to purify, elevate and perfect this heritage," he told the young people. "You can appreciate the many positive values of the diverse Asian cultures. You are also able to discern what is incompatible with your Catholic faith, what is contrary to the life of grace bestowed in baptism, and what aspects of contemporary culture are sinful, corrupt and lead to death."
