Note for the internet: I am just clarifying the Catholic stance. I am not Catholic and not defending them.
Priests cannot reveal what someone tells them in confession. It's a lot like attorney-client privilege, as your priest is supposed to be your advocate before God. Breaking the seal of confession is a big deal (to them) because, just like criminals deserve representation, sinners need to be able to confess.
Kitton mittons scientifically necessary. Don't let your car stomp around making so much noise.
