Except for Jesus of course. Priests have to come from homes, or communities or schools where the priesthood is respected and the vocation is talked about. This cute ad was posted on Shouts in the Piazza. It's from the diocese of St. Augustine.
It struck me as particularly funny because when I first saw the parochial vicar at my parish I thought, 'Wow, he's just a baby!' I'd love to know how long it took to get this picture and how they managed to get this little guy dressed.
