I thought this interview a fascinating conversation on The Diane Rhem Show, mostly because of the parallel I see with the Reformational concept of sola Scriptura. I'm not saying there's a one-to-one correlation here, only that as I listened to Tribe talk about the "invisible Constitution," the similarities were striking. (Tribe is no conservative, by the way. There's quite a bit of empty rhetoric here on abortion.)
We are not, as Christians, people of the book, however, but people of the Word of God, the Word made flesh. Though certainly Christ is made present to us in the hearing of the Scriptures. Please, don't understand my beliefs about the Scriptures as an attempt to belittle them. As a Catholic, I venerate the Scriptures. (Catechism, sections 101ff.).
