Violating the Great Seal of confession is a sin against the Holy Spirit. Which is much worse than any sin against the 6th commandment, no matter how heinous.
The penance given for such heinous crimes against the innocence of children would normally include restitution. The penitent would not be absolved of his guilt unless he made restitution, which would include turning himself in to the authorities for punishment.
This is nothing new. Secular governments throughout history have attempted to compel confessors to break the seal and martyrdom is the final outcome.
This Protestant finds the proposed breach of the priest to parishioner relationship abhorrent. This is violative of the First Amendment protection for religion. I am surprised such legislation would be proposed in deep red North Dakota, but it appears even Republicans are willing to breach the sanctity of the confessional.
