Let us suppose, for a moment, that the second thing seen by the former Saul of Tarsus on the road to Damascus was a mailbox:
As I sat half-listening to the lector at Mass on Sunday morning — my mother and the Holy Roman Catholic and Apostolic Church insist that I go to at least one Mass every year unrelated to someone getting married or dropping dead — it stuck me how much of the Christian Bible, that portion the bitter clingers refer to as the New Testament, is actually mail, twenty-one pieces of first class mail, in fact. I thought this a bit odd at the time. The Buddha found the path to enlightenment while sitting under a bodhi tree, Moses got the Good Word from a bush that burned without burning, thereby causing and preventing forest fires in one fell swoop, and the archangel Gabriel had to tell Muhammad to recite three times before the Prophet finally got the point and started reciting. But Christianity? Christianity comes to us via the faith of the Apostles, the sacrifice of the martyrs, and the exertions of the Roman post office.
Which would be well to remember in case you start wondering what the Romans have ever done for us.
