You know there are some really wonderful and holy bishops... imagine how hard it must be to be them?
What the bishops do and don't do matters a lot but it's not everything. I just worry about the possible converts who are repelled and/or offended. Probably all of us, if we are willing and able, have an indult that is sort of accessible - if we don't want to deal with our own parish bs. And the bishops... you get your good ones and you get your bad ones... always been that way, I guess.
When I was a kid I got kicked in the pants pretty good. My mother had an affair with a priest and so my parents ended up divorced. The Church gave her an annulment even though my dad didn't want one. Then all the collages and posters and CCD garbage. So I kind of left for a while. Until it came to me that the priests and the bishops weren't the Faith at all. They can help if you let them and they can hurt if you let them.
And none of it will matter at the end! Although I'll take one of whatever stripe please, at the end ;-)
Any male Catholic with a modicum of common sense, justice, spirituality, and love for the Church and her faithful people can handle the job.
All four seem to be lacking at times presently.
There is this idea abroad that other things are really the highest qualities of a Bishop (like raising money). Anyone can raise money with a little training. Apparently not everyone has common sense regarding a simple topic like priests fondling young men in the sacristy.
