They're smart enough that they'll be able to find out what was said or not said in a confessional booth?
Can you explain how that's going to happen without surveillance of confessions?
That should never happen during the sacrament of confession. They could say, "After confession, if you would like to talk to me about this more, I would be happy to listen and help you." And I suspect that kind of thing already goes on - priests often make the offer of non-confessional pastoral counseling available to people who ask for it during confessions; it's not the Sacrament of Advice or the Sacrament of Counseling.But one obvious approach if a child in Catholic school is telling a priest about how they are a victim of sexual abuse would be to stop the confession and pull them out of the confession box and say something to the effect of: "look, this is not your fault and you are not the one who is sinning here. But I am obligated to report what you are telling me. If this is something you want to talk to me about I am here to listen. If not, I can find someone else who can help you through this."
Presumably, teachers and school nurses aren't offering the sacrament of reconciliation.Which is exactly what a teacher or school nurse is expected to say if a child comes to them with the same information. It isn't necessarily comfortable to tell a child "I have to report what you are telling me" but it is what you are required to do. Usually it is a cry for help and we are obligated to answer.
Look, no matter how many excuses you make up that you think it should be so, the sacrament of reconciliation is not a place for priests to gather up information to turn over to the government. There are 4 esteemed martyrs who died to preserve the sanctity of the confessional seal; it is completely laughable that the State of Washington thinks they are somehow going to persuade priests to do what neither drowning nor the Republicans' firing squad in the Spanish Civil War could do.
But please go ahead and tell us how this law will be enforced, keeping in mind that a priest will not break the seal of confession and reveal what is said in the confessional booth.
