BARCELONA, Spain (AP) — Pope Leo XIV on Tuesday sought to encourage Spain's young people to persevere in their faith, as he presided over an evening rally that was notable for its frank discussion of depression, domestic violence and "toxic" family relationships.

The U.S.-born pope received a raucous welcome at the Olympic stadium in Barcelona, the second stop of his weeklong visit to Spain that has drawn huge crowds despite the country's strong secular bent.

The crowd, estimated at 40,000, erupted in cheers when Leo emerged from the stands in his popemobile and looped around the grounds. He thrilled sections of the crowd each time he stopped to bless babies or to do the "6-7" hand gesture that has now become a signature.

The event featured several nods to Catalan culture, including a demonstration of the region's famed human tower acrobats, known as castellers. The eight-level tower drew an appreciative applause from the pope after the smallest child reached the top, waved, and then quickly shimmied down.

Leo also spoke in Catalan, more than initially foreseen, during the prayer vigil that featured a question-and-answer session with young adults. Such exchanges are scripted in advance and are typical features of papal trips. But Tuesday's edition was particularly raw given the subject matter Leo covered.

One young woman told Leo of a suicide attempt and the "darkness" she had experienced with bouts of depression. Another spoke about her father's attempt to kill her mother and a childhood spent in juvenile detention. She asked how she could ever forgive her father.

Leo thanked the youths for their honesty and willingness to share their stories publicly. He blamed the malaise on what he said was a society that demands perfection of its youth and silences "moments of darkness and suffering."

He compared the "silent illness" of depression among young people to the suffering of Christ on the cross.

"In those dark hours, as he was dying on the cross, Jesus shared our pain and revealed to us the face of a compassionate God, who bears our sorrows, who suffers with us, weeps our tears and remains at our side with his presence full of love and mercy," Leo said.

But he also identified abusive families where domestic violence is normalized as being behind many problems facing today's young people.

"So many crime reports, even today, reflect a toxic climate in family relationships marked by abuse and oppression and, in particular, by violence against women, which unfortunately often leads to femicide," Leo said.

Leo urged young people to find solace in their faith. And he drew applause when he demanded better health services and care for mental health problems and domestic violence.

"We are all called to address this dramatic reality, both personally and as a society, because we are responsible for confronting it in all its dimensions," he said.

Leo has been emphasizing a message of hope for youths in Spain, a once overwhelmingly Catholic country that experienced a religious crisis after its 20th century dictatorship ended and democracy took root.

Recently, church officials and sociologists alike have pointed to indications that young Spaniards are showing an increasing interest in their spiritual lives, with anecdotal reports of rises in conversions among young adults.

Patricia Garzón, a 25-year-old who attended the prayer vigil with her friend, said her faith helps her every day.

"I believe that it is more difficult (for young people) today because before social media didn't exist, and today we are constantly comparing ourselves with one another (online)," she said. "And we need someone from above to help us, to help us see that he loves us for who we are, not how others want us to see ourselves."

The highlight of Leo's visit to Spain comes Wednesday when he inaugurates the soaring central Tower of Jesus Christ on Barcelona's famed Sagrada Familia basilica.
