A couple of interesting things. Did you hear that the Vatican may have exhumed the bones of the actual St. Paul. That would be kind of cool... if it's true. You can read a little more about it here, here, and here.
And here's an interesting thought I found surfing today: "Peter and Paul were of course not always the best of friends (at least from Paul’s perspective!). But celebrating them together is important: in many ways, they are the Catholic apostle and the Protestant apostle. (Ecumenical) hope springs eternal." (From Cross Talk)
