DUBLIN — Pope Francis faced a lukewarm reception and scattered protests Saturday on his trip to Ireland, with even his vow to rid the church of the "scourge" of sexual abuse and his outrage at those "repugnant crimes" dismissed as an insult by Ireland's wounded victims.

The abuse scandal — which has convulsed Ireland since the 1990s and has exploded anew in the U.S. — took center stage on the first day of Francis' two-day trip to Ireland. The visit was originally intended to celebrate Catholic families but has been overshadowed by the renewed abuse crisis.

A series of abuse allegations have taken their toll in Ireland, and church attendance has plummeted. Francis sought to respond to the outcry by vowing to end sex abuse during a speech to Irish government authorities at Dublin Castle.

"The failure of ecclesiastical authorities — bishops, religious superiors, priests and others — to adequately address these repugnant crimes has rightly given rise to outrage, and remains a source of pain and shame for the Catholic community," he told them. "I myself share these sentiments."

He cited measures taken by his predecessor, Pope Benedict XVI, to respond to the crisis. But while Benedict is credited with cracking down on abusers, he never acknowledged the Vatican's role in fueling a culture of cover-up or sanctioned bishops for failing to protect their flocks from predator priests.

Francis followed his promise with a half-hour meeting with eight survivors of both clerical and institutional abuse and prayed quietly before a candle lit for victims in Dublin's cathedral. But neither his words nor the meeting with victims is likely to assuage demands for heads to roll over the abuse scandal.

"Disappointing, nothing new," was the reaction from Irish abuse survivor Marie Collins, a former member of Francis' sex abuse advisory panel who quit last year in frustration. She later took part in Francis' meeting with seven other abuse survivors, including two priests and a public official.

Colm O'Gorman, who is leading a solidarity rally on Sunday in Dublin for abuse victims, said Francis' remarks about sharing the shame felt by Catholics were an "insult to faithful Catholics, who have no reason to feel shame because of the crimes of the Vatican and the institutional church."

The reception that Francis received in Dublin contrasted sharply with the raucous, rock star welcome that greeted St. John Paul II in 1979 in the first-ever papal visit. No one from the public was at the airport or the roads nearby when Francis arrived Saturday and the streets near a church-run homeless shelter that Francis visited were practically empty despite barricades designed to hold back crowds.

At one protest, people tossed baby shoes to remind the pope of the poor treatment the Catholic church doled out to the children of unwed mothers. Crowds did throng Francis' popemobile route and gathered outside Dublin's cathedral, basking in the sunny weather.

Deeply Catholic Ireland has had one of the world's worst records of clergy sex abuse, crimes that were revealed to its 4.8 million people over the past decade by government-mandated inquiries. The reviews concluded that thousands of children were raped or molested by priests or physically abused in church-run schools — and Irish bishops worked for years to hide those crimes.

After the Irish church enacted tough new norms to fight abuse, it had been looking to the first visit by a pope in 39 years to show a different, more caring church.

More than 37,000 people — most of them young Catholics — signed up to attend a Vatican-sponsored World Meeting of Families that ends Sunday in Dublin, more than twice the number of a rally in Philadelphia three years ago. And many did remain hopeful that Francis' appearance would bring healing.

"I see a lot of new life amongst young people who have a deep committed faith," said Sean Ascogh, a churchgoer in Blessington, southwest of Dublin. "Obviously, they are very disappointed by what has been happening in the church in the last few years, particularly the whole abuse scandals, but I think people can see beyond that."

Francis urged the Irish to recognize that for all its failings, the Catholic Church educated and cared for generations of Irish children in times of famine and great poverty.

Irish Prime Minister Leo Varadkar concurred, saying the church stepped in to care for Irish children when the state did not. But in his speech to the pope at Dublin Castle, he said both church and state had a history of "sorrow and shame," and he urged the pope to ensure that victims of sex abuse find "justice and truth and healing."

Varadkar cited the recent Pennsylvania grand jury report, which found 300 priests had abused more than 1,000 children over 70 years in six dioceses, in urging Francis to "ensure that from words flow actions."

"In recent weeks, we have all listened to heart-breaking stories from Pennsylvania of brutal crimes perpetrated by people within the Catholic Church, and then obscured to protect the institution at the expense of innocent victims," Varadkar said. "It's a story all too tragically familiar here in Ireland."

Ireland's tortured history of abuse has left its mark. Irish voters in recent years have turned their backs on core Catholic teachings. They have overturned a constitutional ban on abortion and legalized divorce, contraception, previously banned homosexual acts and same-sex marriage.

Irish abuse victims and their supporters were to hold a solidarity rally Sunday in Dublin at the same time Francis is celebrating Mass.

Separately, survivors of Ireland's wretched "mother and baby homes" — where children were exiled for the shame of having been born to unwed mothers — were to hold their own demonstration Sunday. The location is Tuam, site of a mass grave of hundreds of babies who died at a church-run home.

Francis will be nearby, visiting the Marian shrine at Knock, but has no plans to visit the grave site.

He did, however, hear about Tuam on Saturday from Ireland's minister for children, Katherine Zappone. Their conversation wasn't released but Francis said her words "still echo in my ears."

An amateur Irish historian, Catherine Corless, traced the deaths of 796 children at the Tuam home to a grave in the orphanage's sewage area. Corless and survivors of the home and their families want to unearth the site and give the children — all of whom were baptized — proper Christian burials.

Zappone's ministry is to recommend this fall whether to accept that proposal or build a memorial at the site.
