VATICAN CITY -- Pope Francis on Thursday called on all those who work with children, starting from the scandal-stained Catholic Church, to join together in an alliance to better prevent sexual and other abuse of minors.

In a message to a conference in Rome about keeping children safe, Francis said the church's own efforts are driven by 鈥渢he sorrow and the shame for not having always been good custodians in protecting minors who were entrusted to our educational and social activities.鈥

Pedophile priests have easy access to children in parishes, schools and Catholic after-school recreational programs.

Their acts of abuse by pedophile priests, coupled with revelations of widespread cover-ups by bishops and other church authorities, have marred the Catholic Church's reputation and eroded the trust of countless rank-and-file faithful in many countries for decades now.

Francis described as urgent the need for 鈥渞enewed training of all those who have educational responsibilities and who work in situations with minors, in the church, in society, in the family.鈥

The pontiff said only with a 鈥渟ystematic action of preventative alliance鈥 will it be possible to combat every form of sexual abuse as well as abuse of 鈥漜onscience and of power.鈥

鈥淢ay the protection of minors be ever more concretely an ordinary priority in the educational action of the Church,鈥 Francis said.

Survivors of sex abuse by priests and by other church officials have been pressing the pope to do more to ensure sexual predators are swiftly brought to justice and prevent a repeat of systemic abuse of minors.
