Steve--Is this the poem that you intended to link to Midweek Motif? The shimmering foolishness of they and it and agnosticism--haha! Proves the point, yes?
I think you got it... that plus my own agnosticism about the whole thing. They really did this, though... I have an old NYTimes article about it. The best thing is, though, that the whole family, down to the present generation, became Catholic and is filled with nuns, priests, and Catholic-School teachers.
I love the irony. It's perfect.
A refreshingly different take on the topic, I'd say. Well done!
