I read somewhere that a candidate for the priesthood should be somebody for whom the discipline of celibacy should be an experienced sacrifice. The theory goes like this: If a man feels no significant sacrifice, then perhaps he is not called to the priesthood. A good priest is a man who would also make a good husband and father. Therefore only men who feel called to marriage would make a good priest.
This goes against, in my view, what Our Lord said, as regards eunuchs and the Kingdom of Heaven. I could be wrong.
If someone can clarify this for me I would appreciate it.
