Would You Baptize an Extraterrestrial? by Guy Consolmagno & Paul Mueller

Book – Lots of people have this idea that science and faith are inherently opposed, but the authors of this book – both astronomers with the Vatican Observatory, one a Jesuit priest and the other a Jesuit brother – are good evidence that doesn’t have to be the case. In six casual, chatty chapters, they discuss everything from the beginning of the universe to the end of it; the nature of Pluto, the Star of Bethlehem, and Galileo’s persecution; and, yes, if they (or rather, if Father Paul) would baptize an extraterrestrial.

The authors are Jesuits, so this is definitely a Catholic perspective on both the universe and on the Bible, but I think it’s illuminating for anyone. They argue that both of those vast and profound entities require you to choose how you’re going to go about understanding them, and that if you choose wrong, you’re just going to be more confused than you started – and they offer examples both from the history of science and from the history of theology.

My favorite chapter, though, was the chapter on Pluto. It turns out that both authors were part of the process of re-defining the elements of our solar system that removed Pluto from the list of planets, and they explain the complicated tangle of human categories, actual celestial bodies, and plain old human emotion that made that process so difficult and controversial.
