Pope Leo at Sagrada Familía: 'We cannot believe in Jesus and promote war'

Before Spain's royals, prime minister and Barcelona Cardinal Juan José Omella in attendance at the Mass, the pope called the basilica an "architectural masterpiece" which is an "eloquent catechesis made of stones, colors and light," recalling how ancient cathedrals were in themselves tools of evangelization.

"In this age in which image is so prevalent, it becomes even more evident how art and beauty are privileged channels of evangelization," he said. 

As the dusk sky contrasted with the illuminated cross atop the basilica following Mass, Leo processed outside and offered his blessing for the building's tallest tower, sprinkling holy water on the sprawling structure and surrounding crowd. The approximately 120,000 people gathered around the basilica held out paper lanterns that pulsated in synchronization, and the entire basilica was illuminated in a choreographed light show that culminated in fireworks. 

Just as Benedict's consecration of the altar opened the basilica's nave for daily Mass — effectively changing the city's relationship with the building — some say that Leo's blessing could change how Catalonians see the Sagrada Família from the outside. 

"For Barcelona, the Sagrada Familía was always seen as a bit of an enemy, due to the Mass tourism," said Chiara Curti, an architect and Sagrada Família expert who has authored two books on the basilica and its architect. "But today, everyone is very proud that this tower of Jesus Christ shines from every part of the city."

"The world has started to identify Barcelona with the Sagrada Família," she told reporters ahead of the Mass, "and now this will make it be identified with a large cross." 

Leo leans into Catalan culture 

For much of his two days in Barcelona, what mattered most to the pope's Catalan audience was not so much what he said but how he said it. 

The polyglot pope put to rest weeks of speculation in the Spanish press over whether he would speak in Catalan with the very first words he spoke at Barcelona's cathedral on Tuesday, beginning his greeting with "Estimats germans i germanes" ("Dear brothers and sisters"). 

From sanctuaries to an olympic stadium, crowds wooed upon Leo's speaking in Catalan, the official language, in tandem with Spanish, of the semi-autonomous region of Catalonia of which Barcelona is the capital. 

From the enthusiasm of the crowds receiving him, it seems his language skills earned him forgiveness from the Catalan public after revealing at the start of the trip that he was a fan of the Real Madrid soccer team, the bitter rival of Barcelona's main team. 

And in contrast with the sea of Spanish flags present at the pope's events in Madrid, sparingly few were seen over the course of his two days in Barcelona — children receiving the pope outside the Abbey of Our Lady of Montserrat waved dual-sided Vatican/Catalonia flags upon his arrival. 

His Barcelona leg, sandwiched between a more politically tinged three-day visit to Madrid and two days that will highlight the plight of migrants in Spain's Canary Islands, took on a more spiritual contour. 

After praying the rosary before the statue of Our Lady of Montserrat — a statue of a Black Madonna venerated throughout northeastern Spain — Leo noted how Jesus' mercy "exposes the violence that can lurk in our words and attitudes."

"Let us ask Mary, Queen of Peace, to teach us to renounce hurtful words, hasty judgment, gossip and slander," he said.

In Barcelona's cathedral, he called on Christians to become modern day "martyrs" in a world marked by deep division and individualism, "that is, witnesses and prophets of unity, of welcome, of harmony and of peace, even at the cost of sacrifice and renunciation."

And in one of the most striking moments of his Barcelona trip the pope responded to the testimony of a woman who shared the story of her battle with depression. 

Leo said there is "something deeply wrong with a certain notion of progress that subjects people to pressures, expectations and tensions that compromise healthy balances," and that Christians must not "spiritualize pain, superficially attributing it to 'God’s will' or to some mysterious plan of his." 

"This risks minimizing that suffering, silencing it and hurting people," he said. "God does not want suffering. He carries it with us and invites us to trust in him with perseverance."
