Some protesters also say they have booked tickets to the event in Phoenix Park but will deliberately not use them as a form of silent protest against the Catholic Church and its actions.
So the president of Ireland, the prime minister of Ireland, and the survivors of abuse in Ireland were hoping for more than tough talk. The visit was originally meant to celebrate Catholic families.
Pope Francis emerged at Ireland's Croke Park stadium last night to applause worthy of even the greatest sporting superstar.
"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.
The pope took to the podium to speak of the most vulnerable.
His refusal to do so during a 2016 trip to Mexico riled some victims, given the country is home to the founder of the Legion of Christ, the Reverend Marcial Maciel, perhaps the most notorious paedophile of the 20th century Catholic Church. But neither his words nor the meeting with victims is likely to assuage demands for heads to roll.
Marie Collins, who was abused by a priest when she was being treated in hospital at the age of 13, was also among the eight.
The Vatican confirmed Francis will meet with victims but provided no details while adding that he was unlikely to announce specific measures to combat sexual abuse.
Critics of the Church have also been preparing for Francis.
His visit is the first by a pope to Ireland in 40 years and is aimed at showing the church understands the problems of ordinary Catholic families.
Later in the day he is due to meet newlyweds and couples about to marry at St Mary's Pro cathedral in Dublin.
The trip, Francis' most direct encounter yet with the ramifications of those scandals, is expected to test whether he can begin to rebuild the church's standing in a country where Catholicism was once the social and religious bedrock.

And Ireland's church attendance has waned from 90% to about 30% as revelations of abuse by Catholic-run institutions continue to damage its moral authority and diminish its influence.
Hundreds of thousands are set to greet the leader of world's Catholics during his two-day visit.
In his speech welcoming the pope, Varadkar said Ireland had a "bitter and broken heritage" of abuse that had left "a legacy of pain and suffering, a shared history of sorrow and shame".
He is due to make a speech at Dublin Castle around lunchtime on Saturday, shortly after meeting Irish Taoiseach Leo Varadkar.
"We must now ensure that from words flow actions".
"There are dark aspects of the Catholic Church's history, as one of our bishops recently said". "It is a story all too tragically familiar here in Ireland".
