I know exactly what the OP is talking about. At a church near my work, there are the old standard anonymous confessionals, and a new Reconciliation Room. Problem is, most often the priest is only in this glassed Room, and rarely are the traditional confessionals used, so the average pentitent is out of luck when it comes to having routine access to an anonymous confessional.
I object just as much to the fact that the entire church – both the people near the head of the line, and especially the people sitting/kneeling within a large segment of the pews – also has a perfect view of the penitent. I have gone to “open” venues before, where several priests hear confessions in all corners of the church after a group penitential rite, but those are the exception, not the rule. It’s a special experience for those who choose to do that every so often, who obtain a special graced experience doing that, but by no means do highly visible confessions dominate at such parishes.
I thought it was dumb that --I think it was-- Australia, decided to have glassed confessionals “because of pedophilia.” Um, if you’re in a traditional confessional, how exactly would the priest be able to touch you, unless he, contrary to all sacramental practice, unilaterally left his seat, opened his door, and then opened yours?
And for adults, what the heck purpose does it serve to humiliate the penitent even more by having everyone stare at him while he’s confessing? For myself, confession is often very emotional. My emotions about it are generally not something I want shared with complete strangers. If I want to experience it communally, I’ll seek a specific scheduled event like that
