<If we criticize the Church for maintaining a relationship with pedophile priests before they're convicted ....>
I don't think the criticism is (or should be) that the bishop continued to have a relationship with the accused; the criticism is that the bishop (all too often) failed to respond appropriately. At ordination, priests are advised to see the bishop as father and each other as brothers. A few years ago, two women turned their teen-age sons in to the police when the sons were wanted for murder. But the mothers did not abandon the sons; they accompanied them as they faced the consequences of their behavior. If these women get that, why can't/don't the bishops? or the rest of us?
<Once a clergy-abuser is in the criminal justice system, then it becomes the state's job -- not the Church's -- to protect society from that person.>
I would submit that the church cannot and should not walk away; but most of the accused are not in the system.
