US President Trump and first lady Melania talk with Pope Francis

Pope Francis urged Donald Trump to use his U.S. presidency to promote peace around the world as the two leaders swapped sparring for smiles in their first face-to-face meeting, at the Vatican yesterday.

Trump’s audience with the 80-year-old pontiff, a keenly-anticipated highlight of his first overseas tour, lasted just under half an hour and concluded with both men smiling.

“He is something,” the president later said of his host. “We had a fantastic meeting.” 

The Vatican described the discussions as “cordial” and stressed the two men’s joint opposition to abortion and shared concern for persecuted Christians in the Middle East.

There was no mention from either side of the two men’s profound differences on climate change, migration, the death penalty and other issues.

Trump told his host as he left: “Thank you. Thank you. I won’t forget what you said.”

The pope had presented Trump with a medallion engraved with an olive tree, the international symbol of peace.

“I give it to you so you can be an instrument of peace,” he said in Spanish. “We can use peace,” Trump replied.

In a lighter moment, Francis referred to Trump’s imposing bulk by asking his wife Melania, “What do you feed him on? Potica?” – a reference to a calorie-laden cake from Slovenia, Melania’s country of birth.

Trump presented the pope with several gifts, including a collection of first editions by Martin Luther King and a bronze sculpture.

Francis gave Trump copies of the three major texts he has published as pope, including one on the environment which urges the industrialized world to curb carbon emissions or risk catastrophic consequences for the planet.

Trump, who has threatened to ignore the Paris accords on emissions and described global warming as a hoax, vowed to read them.

In the last year, the two men have swapped jibes and debated on subjects ranging from migration to unbridled capitalism, as well as the environment.

A Vatican statement highlighted “the joint commitment in favor of life, and freedom of worship and conscience.” Since his November 2016 election, Trump has pleased the Catholic hierarchy by axing rules protecting tax-funded financing of family planning clinics that offer abortions.

Melania, who is a Catholic, and daughter Ivanka were both dressed all in black with lace veils, in keeping with traditional protocol that is no longer obligatory for visiting female dignitaries.

The audience took place in the private library of the Apostolic Palace, the lavish papal residence that Francis does not use, having opted instead for modest lodgings in a guesthouse for visiting clerics.

Afterwards, the Trumps were given a private tour of the Sistine Chapel and St. Peter’s Basilica.

The president then called on Italy’s president and met briefly with Prime Minister Paolo Gentiloni. “We’re loving Italy very much,” Trump said at that stop. “It was an honor to meet the pope.” 

Melania, meanwhile, visited a children’s hospital and Ivanka met women trafficked from Africa for the sex trade on a visit to the St. Egidio religious community.

Francis and Trump’s past spats include the pope describing plans for a border wall with Mexico as not Christian and Trump evoking a possible ”Islamist attack” on the Vatican which would make the pontiff glad to have him as president.

But there have also been conciliatory moves. In 2013, Trump tweeted that “the new pope is a humble man, very much like me” while Francis had promised to judge the man, not the image.

The meeting on May 24 nevertheless provided a reminder of their differences in style, Trump arriving at the Vatican in a jumbo-sized SUV that couldn’t have been further removed from the modest Fiats and Fords Francis prefers.
