If the Catholic Church thinks Priests should be celibate then that is their prerogative. If they think these guys should be like monks who live and breathe their faith 100% of the time, then they should make that clear.
In my personal Christianity I don't see "church leaders" as anything higher than those sitting in the pews, they are also sinners, they should have the job of carrying and preaching the message. If they fail that, they need replaced.
All he can do is advise people based on anecdotal evidence from other people.
He can counsel them based on scripture and church teachings, which is what one expect from a man of the cloth and not a psychologist I think.
Why would people expect more than that?
I would expect unmarried church leaders to be about as good marriage counselors as computer programmers. They can tell us what God wants and how we are expected to behave toward each other, but after that.... *crickets*.
There are some areas of marriage that an unmarried marriage counselor simply cannot give advice on.
It's all good in theory. When it comes to the practical application, they have no experience.
I read a great book once called *And Then I had Kids* written by a lady who had all the answers for child reading until God blessed her with a bunch of kids of her own, including a boisterous set of twins.
And honestly, who would expect someone without children to be qualified to give advice on raising children?
Yet somehow, an unmarried marriage counselor works?
