How about JAIL?
Or if the statute of limitations for prosecution has run out, how about a far away cloistered monastery where they can do penance for the rest of their days, far away from the faithful, and far away from new seminarians.
That's just 2 off the top of my head.
The Dominicans are not a cloistered order. It's unlikely that Trappists would agree to disrupt their lives to take them.
Realities intrude, murphE.
Your suggestion is both prudent, sane, and just.
They should be made to do penance for the rest of their lives, living on a bland and coarse diet, living in a simple, unadorned monastic setting. NO TV, radio, newspaper, computer, etc. Books> Sure......scripture, and the writings of saints and mystics. Music? the chant of the divine office, sung in common.
If they will not submit to this mercy for their souls, then they should be turned loose with no pension, medical insurance or salary. Let them beg the modernists who lov ethem so much for their bread then.
