Pope Francis opened the first-ever papal visit to Iraq on Friday with a plea for the country to protect its centuries-old diversity, urging Muslims to embrace their Christian neighbors as a precious resource and asking the embattled Christian community – “though small like a mustard seed”  – to persevere.

Francis brushed aside the coronavirus pandemic and security concerns to resume his globe-trotting papacy after a year-long hiatus spent under the coronavirus disease 2019 (Covid-19) lockdown in Vatican City. His primary aim over the weekend is to encourage Iraq’s dwindling Christian population, which was violently persecuted by the Islamic State group and still faces discrimination by the Muslim majority, to stay and help rebuild the country devastated by wars and strife.

“Only if we learn to look beyond our differences and see each other as members of the same human family,” Francis told Iraqi authorities in his welcoming address, “will we be able to begin an effective process of rebuilding and leave to future generations a better, more just and more humane world.”

The 84-year-old pope donned a facemask during the flight from Rome and throughout all his protocol visits, as did his hosts. But the masks came off when the leaders sat down to talk, and social distancing and other health measures appeared lax at the airport and on the streets of Baghdad, despite the country’s worsening Covid-19 outbreak.

The government is eager to show off the relative stability it has achieved after the defeat of the IS “caliphate.” Nonetheless, security measures were tight.

Francis, who relishes plunging into crowds and likes to travel in an open-sided popemobile, was transported around Baghdad in an armored black BMWi750, flanked by rows of motorcycle police. It was believed to be the first time Francis had used a bulletproof car — both to protect him and keep crowds from forming.

Iraqis, though, seemed keen to welcome Francis and the global attention his visit brought. Some lined the road to cheer his motorcade. Banners and posters in central Baghdad depicted Francis with the slogan “We are all Brothers.”

Some hoping to get close were sorely disappointed by the heavy security cordons.

“It was my great wish to meet the pope and pray for my sick daughter and pray for her to be healed. But this wish was not fulfilled,” said Raad William Georges, a 52-year-old father of three who said he was turned away when he tried to see Francis during his visit to Our Lady of Salvation Cathedral in the Karrada neighborhood.

“This opportunity will not be repeated,” he said ruefully. “I will try tomorrow, I know it will not happen, but I will try.”

Francis told reporters aboard the papal plane that he was happy to be resuming his travels again and said it was particularly symbolic that his first trip was to Iraq, the traditional birthplace of Abraham, revered by Muslims, Christians and Jews.

“This is an emblematic journey,” he said. “It is also a duty to a land tormented by many years.”
