(CNN) – A small explosive device was found Sunday near a religious sanctuary that Pope Francis is to visit in Brazil on Wednesday, the state of Sao Paulo military police confirm to CNN.
The disclosure came soon after the Francis, making his first visit outside Rome since his March election, delivered remarks to Brazilian dignitaries.
As the pope was driven from the airport to downtown Rio, crowds mobbed his small, silver car, reaching out to touch the first Latin American’s pontiff. Later, they lined packed streets as the “pope mobile” wound through this city’s downtown.
Pope Francis has already proven himself a remarkably unpretentious public figure, famously renouncing, for instance, his luxurious apartment and chauffeur-driven limousine.
That self-effacing persona was on display again Monday upon his arrival in Rio de Janeiro, where Francis said he wanted to “knock gently” on Brazil’s door during his first overseas journey, making sure it was OK to proceed.
“I ask permission to come in and spend this week with you,” the pope said to his somewhat startled hosts.
Francis arrived in Rio on Monday for the start of “World Youth Day,” which, despite its name, is actually a weeklong gathering of Catholic youth from around the world. It was launched by the late Pope John Paul II in the mid-1980s.
In truth, it would be tough to find anyone in Brazil right now inclined to refuse Francis permission to enter.
Those looking forward to the papal sojourn include hundreds of thousands of pumped-up young Catholic pilgrims, here to take part in the church’s youth festival; a Brazilian government eager for a good news cycle after a summer of discontent; agitated Brazilian protesters, hoping for a papal blessing for their demands; even hordes of journalists with deadlines to meet.
After touching down, Francis also offered an echo of his identity as the “pope of the poor.”
“I have neither silver nor gold,” he said, “but I bring with me the most precious thing given to me: Jesus Christ!
The pope challenged young people to “create a world of brothers and sisters,” and older generations to ensure that today’s youth have “the material and spiritual conditions for their full development,” including “safety and education” as well as “lasting values.”
Earlier Monday aboard the papal plane en route to Rio, Francis worried aloud about what he called a “throwaway culture” that neglects young people and the elderly. He said elderly persons can offer “the wisdom of life, the wisdom of the past, the wisdom of our country and our family.”
Local organizers said an estimated 700,000 youth from various parts of the world have already arrived in Rio de Janeiro to greet Francis, and some projections peg the final total at around 2 million for a youth vigil with the pope on Saturday and his concluding open-air Mass on Sunday.
Though public reaction so far suggests Francis made a strong debut, the weeklong trip certainly will have it challenges.
Latin America has long been a Catholic stronghold, but in recent years evangelical and Pentecostal Protestants have made deep inroads.
In Brazil, a recent study found that a quarter-century ago Brazil was 90% Catholic, while today it is 65%. There’s also a rising cohort of secular Latin Americans with no religious affiliation, especially among youth and city-dwellers.
Moreover, of the 21 nations usually reckoned as part of Latin America, 14 of them are currently led by center-left governments that have sometimes crossed swords with the region’s Catholic leaders over issues such as abortion and same-sex marriage – including in the pope’s home nation of Argentina.
Brazil has also recently been gripped by an anti-establishment mood, fueled by anger over spending on splashy mega-events such as the 2014 World Cup and the 2016 Olympics, while many ordinary people believe that services such as education, health care and transportation languish.
So far, there’s little indication that protesters want to embarrass the pope. Instead, they seem to be hoping to take advantage of his moral authority to bring attention to their cause. Later this week, one group that helped kindle the massive June demonstrations has plans for a rally under the banner “Pope, look how we’re treated!”
The greater danger for Francis may be that all sides in the country’s tensions may want to spin his message their way, especially with one eye on presidential elections in Brazil scheduled for next year.
If journalists aboard the papal plane today were hoping to draw Francis into a discussion of those challenges, they came away disappointed.
Francis walked back to the press compartment shortly after takeoff and spoke for only five minutes, focusing on the risks of a “throwaway society” that neglects both its youth and its elderly.
“I don’t give interviews,” the pope said by way of explanation.
“Why, I don’t know, but I can’t … It’s a little difficult for me, but I’m grateful for your company,” he said.
Yet part of Francis’ charm is that this skittishness didn’t come off as a snub, because the pope proceeded to spend the better part of the next hour standing in the front of the economy cabin of the papal plane to personally greet each of the roughly 70 journalists on board.
Monday afternoon Francis was scheduled to meet Brazilian President Dilma Rousseff at the Presidential Palace, and then the 76-year-old pontiff will take a day of rest on Tuesday before heading north of Rio to the famed Brazilian Marian shrine of Aparecida on Wednesday.
The pontiff’s schedule culminates with a major youth vigil in Rio on Saturday night and a massive open-air Mass that organizers said could draw as many as 2 million people to a field outside Rio on Sunday morning.
