Pete Enns appeals to mysticism but it sounds like sentimentality and even a tad anti-intellectual:
I have come to believe that the life of Christian faith is not fundamentally “rational,” by which I mean faith in God is necessarily trans-rational (not anti-rational) but not “captureable” by our minds. It’s mysterious. It’s mystical. After all, this is a faith that calls upon its adherents to “participate in the divine nature” (2 Peter 1:4).
It proclaims God as the creator of all there is, and the more we learn about that creation, the more we are—or should be—at a loss for words. A universe that is about 14 billion years old and 100 billion light years across, containing billions of galaxies—the closest one to ours is 2.5 million light years away—with each galaxy containing billions of stars—the closest one being 4.2 light years (= about 25 trillion miles) away. At the other end of the spectrum are subatomic particles—the very phrase defies comprehension—and now we hear of string theory and the multiverse (or meta-universe).
If God exists, what can any of us possibly add to the conversation? The God who did this is the one we are aiming to understand. So, “mystery” seems to be an operative category for thinking about theology.
That’s an odd observation for someone who writes as much as Pete does, and for someone whose job is to study a book. It feels like a dodge. But it does confirm the old observation that liberal Protestants were not really rationalists. They were Ph.D.s who wound up appealing to mysticism as their justification.
I wonder how that plays in grad school.
