Whoever came up with that title, which sounds like the ultimate MTV dating challenge, does a disservice to this five-part series. The four young men profiled here contemplate becoming priests, but they don't really seem all that torn between the flesh and the spirit, even if one of them has a girlfriend who describes him as a "zealous, on-fire, amazing Catholic man." The show is respectful, decent and moving. Steve Horvath, a former consultant, goes to Guatemala as a missionary and breaks down weeping when he realizes he doesn't have the courage to deal with poverty. But as one man goes on a pilgrimage (to Buffalo!) and another drags an 80-lb. cross 22 miles, you may wonder whether these physical acts of faith are undertaken partly to provide the cameras with some meaty footage. St. Augustine found God when he heard a child singing, but that wouldn't have made good reality TV.
