At the Vatican, a prominent member of a commission advising Pope Francis on how to end clerical sexual abuse stepped down this week to protest what she described as inaction by the church. Marie Collins, an Irish survivor of childhood sexual assault by a priest, said Wednesday she could no longer work with the commission, because Vatican officials refused to implement basic protections for children and vulnerable adults. Collins’s resignation came as the archdiocese of New York petitioned a court for permission to mortgage $100 million worth of church property in Manhattan in order to fund compensation for victims of sexual abuse by priests.
