The LDS Church has a lay clergy, consequently, there is no professional clergy. Romney never made a dime for his services as an LDS bishop ... he did it only for the love of Jesus Christ.
This isn’t about money. This is about electing a cultist to the Presidency.
He did it because he was ‘called’ to it by his Stake President. Mormons don’t usually use the term Bishop after they are ‘released’ from the calling (usually about 2 years but it varies).
However, it is a bit much to say he did it for the love of Christ. Bishopric calling is somewhat common and when you are ‘called’ to ANY job in the LDS you are expected to serve. It is also a stepping stone to other higher callings like Stake President.
Tepid is right, though, they don’t get paid, ANYMORE. They used to though.
You say that as if it were a "good" thing.
Tell us teppe, does having no professional psychology training as a bishop help or not? How about training in marriage counseling? Counseling teens?
No, I daresay that having a "good" mormon promoted from within the ranks for checking off boxes on the exaltation checklist is not a "good" thing.
I've personally seen too many mormons hurt by an inept, ineffective and untrained "layman".
