DUBLIN (AP) — A prominent Irish survivor of priestly sexual abuse has told a Vatican-sponsored conference that the Holy See must put in place "robust structures" to hold accountable bishops and Vatican officials who fail to protect children from predator priests.

Marie Collins, a former member of Pope Francis' abuse advisory board, urged Catholic families attending the Dublin conference Friday to ask why the pope scrapped a proposed accountability tribunal for negligent church leaders.

Speaking on the eve of Francis' arrival at the conference, Collins also said Catholics should ask why the church routinely opposes removing statute of limitations to prosecute and sue abusers, despite claiming to be on the side of victims.

She said: "The actions of the church do not match the words, and they are in fact totally the opposite."
