The Survivors Network of those Abused by Priests, or SNAP, called for Cardinal Francis George to be disciplined along with anyone else who took slow or no action when abuse was alleged.
They also wanted those who didn't report the allegations to be fired, the Chicago Tribune reports.
Rev. Daniel McCormack has been suspended from St. Agatha after three boys accused him of molesting them.
A lawsuit filed against the archdiocese claims George didn't do enough to stop the abuse that a nun reported in 2000.
McCormack was allowed to stay at his parish even though police were investigating the claims and George said Thursday reforms would be made so that didn't happen again.
