I get that confessional secrecy supports the sacrament’s popularity. But I still don’t see that the priest would be breaking the seal. He would be withholding absolution. The seal would remain. Would you have the same objection to the priest requiring an apology to the victim along with an acknowledgement that what he did was wrong and unlawful?
The victim already knows about the sin, so IF that was required (I’m not at all confident it can be utterly required, though it can and should be strongly encouraged, and the priest may have logical grounds for concluding a flat refusal to do so–if it isn’t born out of some powerful mitigating factor like fear, for instance if the victim hadn’t been victimized in years and the abuser wasn’t sure if bringing it up wouldn’t cause more pain than it helped–indicates a lack of contrition which IS valid grounds for refusal of absolution) it of course wouldn’t be a violation of the seal, because the penitent is not being required to
reveal his sins to anyone. Again, it’s apples to oranges: One requirement is
specifically aimed toward informing people (through the sinner himself as a mouthpiece) outside of the confessional about the sinner’s deeds, the protection from which is the very purpose of the seal, and the other requirement is about an apology to someone who already knew. Again, I’m not at all confident even requiring
that, and absolutely refusing him absolution if he didn’t, is licit,
if the sinner arguably has any other remotely conceivable and reasonable motive for refusing to do so besides a lack of contrition, but even aside from this lack of confidence on my part, it’s simply not in the same realm of trying to find a “loophole” to force the sinner to reveal his sins to people who don’t know it–which is (obviously and clearly)–in violation of the very purpose of the seal in the first place.
