A clergy sex-abuse victim criticized Pope Francis's speech after he announced that he met with clergy sex-abuse victims on calling for those responsible for Philadelphia's own scandal to be held accountable.

Becky Iianni, spokeswoman from the Survivors Network of those Abused by Priests, said that she has heard the pope discuss sex-abuse before, but 'what we really need is action'.

Francis spoke at St Martin's Chapel in in St. Charles Borromeo Seminary in Wynnewood, Pennsylvania, on Sunday where he said that he owes victims of sexual abuse 'gratitude for their great value'.

'God weeps for the sexually abuse of children,' he said during his address. 'I commit to the zealous oversight to ensure that youth are protected and that all responsible will be held accountable.'

Iianni claims that the new Vatican tribunal set up by Francis used to prosecute bishops who failed to protect their flock by covering up for pedophile priests rather than reporting them to police will not be effective.

'I don't believe that the process has been set up. Our issue is how long is it going to take to set up? How long is it going to take to see if it's effective?' Ianni said in an interview with CNN.

She added: 'The pope could fire, demote or publicly denounce any bishop. He could do that without the process.

'Do we need a commission to study something we've known about since the 1980s? I don't think those steps are going to protect children.'

She said that believes that what will help abusers is posting the names of alleged abusers online for everyone to see. She also called for the pope to turn over records and documents about accused members of the clergy.

Iannia said she is, however, glad that the pope met with victims and spoke about sex abuse during his address of family.

'I truly hope that those victims find healing but what about the rest of the victims? I think what needs - I know myself I need - to know that another child won't go through what I went through as a child,' she said.

Prior to his address of family, Pope Francis was greeted by seminarians as he walked through the chapel. He spoke of Philadelphia's sex-abuse scandal and the importance of family.

The last grand jury accused the Philadelphia diocese in 2011 of keeping on assignment more than three dozen priests facing serious abuse accusations, despite a 2002 pledge by the US Conference of Catholic Bishops to oust any guilty clergy.

The same grand jury indicted a priest who had overseen clergy for the archdiocese, Monsignor William Lynn.

Cardinal Justin Rigali, the former Archbishop of Philadelphia who retired in 2011 amid a scandal over clergy sex abuse, celebrated Mass with Francis on Saturday.

Francis has decided to create a new Vatican tribunal to prosecute bishops who failed to protect their flock by covering up for pedophile priests rather than reporting them to police.

'In my heart there stories of suffering, of those youth who were sexually abused,' the pope said. 'And it continues to be on my mind that the people who had the responsibility to take care of these tender ones violated that trust and caused them great pain.'

He added: 'Those who have survived this abuse have become true heralds of mercy. Humbly we owe each of them our gratitude for their great value as they have had to suffer terrible abuse.'

SNAP director David Clohessy dismissed the meeting as an exercise in public relations.

'Is a child anywhere on Earth safer now that a pope, for maybe the seventh or eighth time or ninth time, has briefly chatted with abuse victims? No,' Clohessy wrote in a statement.

He continued: 'To give some perspective, let's assume that roughly the same percentage of priests molest the same percentage of kids across the globe.

'In the U.S., in 2012, two church experts estimate 100,000 kids in the U.S. The US is about 6 percent of the world's population.

'If you do the math, that means there are more than 1.5 million men and women on this planet who have been raped, sodomized or molested by Catholic priests.'

The Rev Tom Doyle, a canon lawyer who worked at the Vatican embassy in Washington and is now an advocate for victims, said that including more than just victims of abusive clergy 'seriously minimizes' the problem in the church.

Francis said that he owes victims of sexual abuse 'gratitude for their great value' before announcing his commitment to 'ensure that youth are protected and that all responsible will be held accountable'

'We don't think we're going to get any real support to change this from the leadership in the Vatican,' Doyle said in a phone interview. 'They're having this big meeting of families. But there's been no real room for all the families that the Catholic Church has destroyed through sexual abuse.'

The Vatican spokesman, the Rev. Federico Lombardi, said the pope met with the survivors for a half-hour at the San Carlo Borromeo seminary. He said the pope prayed with them, listened to their stories and expressed his closeness in their suffering and his 'pain and shame' in the case of those abused by priests.

Later on Sunday morning, Francis headed to Curran-Fromhold Correctional Facility to visit with inmates - a cross-section of suspected killers, rapists, mobsters.

Prison ministry has been a hallmark of Francis' pontificate. He meets often with inmates and has washed prisoners' feet during pre-Easter rituals. He opposes the death penalty in all circumstances and has called for the abolition of life imprisonment and solitary confinement.

On his final day in the United States, Pope Francis will celebrate a climactic outdoor Mass on the Benjamin Franklin Parkway in front of a crowd of 1million people before flying back to Rome.

Organizers have said they expect one million people to turn out Sunday for Francis' final Mass in the United States, a nation the Argentine is visiting for the first time.

At the Mass, six families - from Australia, Congo, Cuba, France, Syria and Vietnam - will receive Francis-signed copies of the Gospel of St. Luke. They'll get an additional 100,000 copies to distribute in their home countries.

'I'm going to give it to the people who need it the most,' said Thomas Coorey, a dentist and father of four from Sydney. 'I want to give it to the people who don't have access to the word of God.'

He called Francis 'the most inspirational and amazing pope that could breathe life into this church of mine. And I'm so grateful to have a leader like him who's so humble and such a true servant of God.'

It's been a common sentiment throughout the pope's visit to Washington, D.C., New York and Philadelphia.
