if they’re not successors to St. Pete, then they can teach catechism.
That's probably not all that popular in Latin America (among that crowd of priests and bishops who've always had their women friends).
No doubt this generates rumors.
I wouldn’t let them near a Catechism or a teaching role with any discretion—but if they want to demonstrate faithfully doing public penance and reparation for sins, both their own and others, their certainly is a need. They also might lead the Rosary before Mass. I’d even be willing to let them serve as sub-deacons, if they are suitable—that would be a good thing to leave to the disceretion of the bishop. :)
