11b is the answer.
However, I would not say the Bible is a book of science either as this leads to fundamentalism.
St. Thomas explains this well: ‘But those things which cannot pertain to salvation are outside the matter of prophecy. Hence, Augustine says: “Although our authors knew what shape heaven is, [the spirit] wants to speak through them only that which is useful for salvation. And to the Gospel of St. John (16:13), “But when he, the Spirit of truth, is come, he will teach you all truth,” the Gloss adds: “necessary for salvation.”
Moreover, I say necessary for salvation, whether they are necessary for instruction in the faith or for the formation of morals. But many things which are proved in the sciences can be useful for this, as, for instance, that our understanding is incorruptible, and also those things which when considered in creatures lead to admiration of the divine wisdom and power. Hence, we find that mention of these is made in Holy Scripture.’ (de Veritate, XII, 2).
Great questions! Admittedly I was unsure on a couple of them but I’ve learned a tremendous amount since reading Ron’s blog and forum. I hope I didn’t do too bad.
