Ages of the Church
Talk of Pope Francis as "the first post-Vatican II pope" brings to mind the three epochs in the life of an adult Catholic layman:
When your new pastor is younger than you are.
When your new bishop is younger than you are.
When the new Pope is younger than you are.
I've reached the first epoch, but not the second. And though I've been Catholic a few years longer than Pope Francis has been a priest, I'm not quite at the point where I can say of the Pope -- quoting a Spike Jones lyric that gets funnier every year -- "He's a young fellow about my age."
