Pope Leo XIV journeyed to Istanbul on Saturday, making a notable visit to the famed Blue Mosque. While he chose not to engage in prayer, his primary objective was to strengthen connections with Orthodox leaders and encourage efforts to unite Eastern and Western churches.

As part of the visit, Pope Leo respectfully removed his shoes and walked through the 17th-century mosque wearing white socks. He marveled at the intricate tiled domes and Arabic calligraphy adorning the columns, guided by an imam who highlighted the mosque’s architectural beauty.

Originally, the Vatican indicated that Pope Leo would take a “brief moment of silent prayer” during his visit. However, he opted not to do so. Imam Asgin Tunca of the mosque mentioned that he had extended an invitation for the pope to pray, noting the mosque as “Allah’s house,” but the pope politely declined.

Vatican spokesperson Matteo Bruni later clarified, “The pope embraced his visit to the mosque in silence, maintaining a contemplative and respectful attitude towards the sanctity of the space and the faith of those who worship there.”

The Vatican then sent out a corrected version of its bulletin about the trip, removing reference to the planned “brief moment of silent prayer,” without further explanation.

Leo, history’s first American pope, was following in the footsteps of his recent predecessors, who all made high-profile visits to the Sultan Ahmed Mosque, as it is officially known, in a gesture of respect to Turkey’s Muslim majority.

Papal visits to Blue Mosque often raise questions

But the visits have always raised questions about whether the pope would pray in the Muslim house of worship, or at the very least pause to gather thoughts in a meditative silence.

When Pope Benedict XVI visited Turkey in 2006, tensions were high because Benedict had offended many in the Muslim world a few months earlier with a speech in Regensburg, Germany that was widely interpreted as linking Islam and violence.

The Vatican added a visit to the Blue Mosque at the last minute in a bid to reach out to Muslims. He observed a moment of silent prayer, head bowed, as the imam prayed next to him, facing east.

Benedict later thanked him “for this moment of prayer” for what was only the second time a pope had visited a mosque, after St. John Paul II visited one briefly in Syria in 2001.

There were no doubts in 2014 when Pope Francis visited the Blue Mosque: He stood for two minutes of silent prayer facing east, his head bowed, eyes closed and hands clasped in front of him. The Grand Mufti of Istanbul, Rahmi Yaran, told the pope afterwards, “May God accept it.”

With Leo, though, even the Vatican seemed caught off guard by his decision not to pray. The Holy See had to correct the official record of the visit after it originally kept the planned reference to him pausing for prayer.

Speaking to reporters after the visit, the imam Tunca said he had told the pope: “It’s not my house, not your house, (it’s the) house of Allah.” He said he invited Leo to worship “But he said, ‘That’s OK.’”

“He wanted to see the mosque, wanted to feel (the) atmosphere of the mosque, I think. And was very pleased,” he said.

There was also another change to the official program, after the Vatican said the head of Turkey’s Diyanet religious affairs directorate would accompany Leo at the mosque. He didn’t come and a spokesman from the Diyanet said he wasn’t supposed to, since he had welcomed Leo in Ankara.

Hagia Sophia left off itinerary

Past popes have also visited the nearby Hagia Sophia landmark, once one of the most important historic cathedrals in Christianity and a United Nations-designated world heritage site.

But Leo left that visit off his itinerary. In July 2020, Turkey converted Hagia Sophia from a museum back into a mosque, a move that drew widespread international criticism, including from the Vatican.

After the mosque visit, Leo held a private meeting with Turkey’s Christian leaders at the Syriac Orthodox Church of Mor Ephrem. In the afternoon, he prayed with the spiritual leader of the world’s Orthodox Christians, Patriarch Bartholomew, at the patriarchal church of Saint George.

There, they prayed the doxology, a hymn of praise and glory to God, and signed a joint declaration vowing to take courageous steps on the path to unity including to find a common date for Easter.

Eastern and Western churches split in the Great Schism of 1054, a divide precipitated largely by disagreements over the primacy of the pope. While ties have warmed, they remain divided and other schisms have formed.

“It is our shared desire to continue the process of exploring a possible solution for celebrating together the Feast of Feasts every year,” the joint statement said, referring to Easter.

The Vatican said in his remarks to the patriarchs gathered, Leo pointed to the next Holy Year to be celebrated by Christians, in 2033 on the anniversary of Christ’s crucifixion, and invited them to go to Jerusalem on “a journey that leads to full unity.”

Leo’s final event was a Catholic Mass in Istanbul’s Volkswagen Arena for the country’s Catholic community, who number 33,000 in a country of more than 85 million people, most of whom are Sunni Muslim.

The Airbus software update doesn’t spare pope

While Leo was focusing on bolstering relations with Orthodox Christians and Muslims, trip organizers were dealing with more mundane issues.

Leo’s ITA Airways Airbus A320neo charter was among those caught up in the worldwide Airbus software update, ordered by the European Union Aviation Safety Agency. The order came after an analysis found the computer code may have contributed to a sudden drop in the altitude of a JetBlue plane last month.

The Vatican spokesman, Matteo Bruni, said Saturday that ITA was working on the issue. He said the necessary monitor to update the aircraft was on its way to Istanbul from Rome along with the technician who would install it.

Leo is scheduled to fly from Istanbul to Beirut, Lebanon, on Sunday afternoon for the second leg of his inaugural trip as pope.
