At the end of the movie "Spotlight," the screen went black before a message appeared noting that The Boston Globe's investigative reporting team published nearly 600 stories, in 2002 alone, about sexual abuse by Catholic clergy.

 The next screen noted, "249 priests and brothers were publicly accused of sexual abuse within the Boston Archdiocese."

 But there was more. The first time Sister Veronica Openibo of Nigeria saw this film -- which won the Oscar for Best Picture in 2016 -- she was stunned to see four screens packed with the names of 223 American dioceses and nations in which major abuse scandals had been uncovered.

 "Tears of sorrow flowed," she said, speaking at the Vatican's global summit on clergy sexual abuse. "How could the clerical church have kept silent, covering these atrocities? The silence, the carrying of the secrets in the hearts of the perpetrators, the length of the abuses and the constant transfers of perpetrators are unimaginable."

Didn't any of these priests and bishops, she asked, go to confession? Didn't they wrestle with their sins while talking with the spiritual directors who guide their lives? Later, she went further, asking why these clergy were allowed to remain in ministry after committing these atrocities. Why weren't they defrocked?

"We proclaim the Ten Commandments and parade ourselves as being the custodians of moral standards, values and good behavior in society," said Openibo, who on several occasions turned to speak to Pope Francis, seated nearby. She is the first African to lead the Society of the Holy Child Jesus and one of three women who addressed the nearly 200 bishops at the recent summit. Openibo was the only person from Africa's booming churches chosen to speak.

"Hypocrites at times? Yes," she asked. "Why did we keep silent for so long? How can we turn this around for a time to evangelize, catechize and educate all the members of the church, including clergy and religious? Is it true that most bishops did nothing about the sexual abuse of children? Some did and some did not, out of fear or cover-up."
