Bono met the Pope Sept. 19 to sign an agreement between his charity, ONE, and the Scholas Occurentes educational charity supported by Pope Francis.
During the half-hour meeting, Bono said, he brought up Pope Francis' recent trip to Ireland and the concerns there about the sexual abuse crisis.
The Pope was "aghast," Bono said. "I thought he was sincere."
"I think he is an extraordinary man for extraordinary times," the singer said.
ONE is a campaign and advocacy effort working to end extreme poverty, especially in Africa. One of its current focuses, Bono told reporters Sept. 19, is education for girls and young women. Some "130 million girls around the world do not go to school, because they are girls," he said.
"Poverty is sexist" is the campaign slogan, he said.
Scholas began in Pope Francis' Archdiocese of Buenos Aires, supporting education in poor neighborhoods by pairing their schools with private schools and institutions in wealthier neighborhoods. The organization has grown to other countries and supports a variety of exchange programs aimed at promoting education, encouraging creativity and teaching young people about respect, tolerance and peace.
"We haven't figured out what we are going to do together," Bono said, "but we sort of have a crush on each other."
Describing Jose Maria del Corral, president of Scholas, Bono said that "honestly, he is quite a radical thinker and I felt quite old-fashioned sitting next to him." Bono was talking about teaching children how to read and write and "get to advanced math and art later. And he was like, 'Start with art. And start with the creative life and you'll get a better result.'"
Bono said the conversation with the Pope touched on many topics, including poverty, commerce and meeting the U.N. Sustainable Development Goals.
They spoke, he said, "about how we have to rethink the wild beast that is capitalism and how, though it is not immoral, it is amoral and it requires our instruction. He's very keen on that."
Bono was an outspoken figure in repealing Ireland's Eighth Amendment, which protected the rights of the unborn child. Irish voters opted to remove the right to life of the unborn from the country's constitution May 26, paving the way for abortion on demand up to 12 weeks.
