The above poster is a part of a new vocations campaign for the Roman Catholic Church. I like to call it "Lookin' Good 'n [not] Gettin' Laid."
In all seriousness, I think the poster, and its attendant campaign, do a lot to romanticize and glamourize the image of the priest and the institution of the priesthood more than is good or necessary. The priesthood is not a pretty, glamourous thing. A sobbing widdow crying into your shoulder is no more glamourous than a dying man coughing blood onto your surplice when you kneel beside him to hear his final confession.
There's joy to be found, certainly, in the long hours, the people whose lives you affect in ways large and small, but it's hardly a job for pretty boys. Don't do it 'cause it's cool, do it because you're driven to do it. If you're not driven to do it, you wont for very long.
And think, my sons, about those long, cold, lonely nights. Think about never knowing the joy or beauty to be found in holding a woman in your arms as she falls asleep with her head against your chest.
It ain't pretty. Is it still worth it?
