SINGAPORE (AP) — When Pope Francis arrives Wednesday in Asia’s financial powerhouse Singapore for the last leg of a four-nation tour, he is expected to bring his message of unity and hope to one of the world’s richest nations.

The 11-day trip, which earlier took him to Indonesia,Papua New Guinea and East Timor, is the longest for the 87-year-old pontiff since becoming head of the Catholic Church in 2013. Francis will be the second pope to visit Singapore, after a five-hour stopover by the late John Paul II in 1986.

Here’s what to know about Pope Francis' three-day stay in Singapore:

Why is Francis visiting Singapore?

Singapore was originally part of Francis’ travel plans to the region in 2020 but it was derailed by the COVID-19 pandemic.

The island city-state at the tip of the Malay peninsula has a small population of just under 6 million people and lacks natural resources, but it is a heavyweight in regional and international affairs. Astute leadership, its strategic location and reputation as one of the most open and least corrupt economies had transformed Singapore into a bustling financial giant and maritime and aviation hubs in just 59 years after independence.

Singapore is a strategic U.S. partner but also maintains close ties with China. Ethnic Chinese account for about three-quarters of its residents followed by minority Muslims and Indians.

According to a 2020 Singapore population census, Buddhists make up about 31%. About a fifth of the population claimed no religious belief, while Christians account for almost 19% and Muslims about 15%.

Singapore has four official languages: English, Malay, Mandarin and Tamil, reflecting its multicultural identity and heritage.

“Singapore and the Holy See share a common interest in promoting interfaith dialogue and understanding. Pope Francis’ state visit is also the first papal visit to Singapore in almost 40 years,” Singapore’s Foreign Ministry said.

In a city ranked as one of the most expensive to live in, Singapore’s Cardinal WIlliam Goh said that key themes frequently emphasised by Francis such as human dignity, inclusiveness, interreligious dialogue, family values, the need to manage artificial intelligence responsibly and care for the environment were of particular relevance.

“As such, Pope Francis’ visit is highly anticipated and warmly welcomed not only by the Catholic faithful, but also by the wider society.” Goh said in a written response to The Associated Press. “After the apostolic visit is done, I pray that Singapore will be filled with hope — a profound, divine hope.”

What's on the pope's itinerary?

After flying in from Dili, East Timor, on Wednesday, Pope Francis will hold a private meeting with members of the Society of Jesus (Jesuits).

On Thursday, he will receive an official welcome at Parliament House and meet Singapore Prime Minister Lawrence Wong and President Tharman Shanmugaratnam. He will also meet government officials, civil society and the diplomatic corps at the National University of Singapore.

The highlight will be a public Mass at the 55,000-seat National Stadium in the evening. Those attending include Catholics from neighboring Malaysia and Brunei. Francis will make a tour around the stadium pitch to greet the faithful in his Popemobile before delivering his homily.

On the last day, Francis will visit elderly residents at the St Theresa’s Home. He will also hold an interreligious meeting with youths at the Catholic Junior College.

How influential is the church in Singapore?

The church marked 200 years in Singapore in 2021. The Archdiocese of Singapore was formed in 1972, seven years after Singapore's independence. Diplomatic relations with the Holy See were established in 1981.

In Singapore’s early years, Cardinal Goh said the church’s work in education and health care were important contributors to national development.

“Many of the country’s top leaders in both the public and private spheres were formed in Catholic schools; and many basic health care needs were provided by Church-run health care institutions,” he wrote on the Vatican News website.

The church supports 395,000 Catholics in Singapore with its 29 parish churches, three devotional churches, 53 schools, 47 humanitarian organizations and two health care institutions. Goh said the church holds frequent dialogue with the government, which views it as an important contributor and shaper of Singapore's social fabric.

Goh, Singapore's first cardinal installed by Francis in 2022, is a member of two Presidential Councils that advise the government on matters relating to racial and religious harmony and minority rights.

“As the final stop on this apostolic journey, Singapore stands as a testament to peaceful coexistence in a modern, multicultural, and multi-religious society," Goh wrote in his reply to the AP. "This reflects the spirit of unity and diversity that Pope Francis has emphasized throughout his pontification.”
