Schönborn Clarifies

Though taking the name "DarwinCatholic" for this blog, I'd never really intended to spend much time on Evolution vs. Creationism. Still, it's a topic that interests me, so...

John Allen offers some more insight into Schönborn's NYTimes essay in his Word From Rome this week. One of the really refreshing things about Allen's reporting (I guess I'll have to be a little less uncharitable about the National Catholic Reporter) is that he's not just a controversy chaser. Unlike 90% of reporters, he seems seriously interested in the topics being discussed, and so he'll run detailed follow-ups like this for weeks till he feels like he's got to the bottom of a topic.

I quoted scientists and theologians who argued that in thinking about the church and evolution, it's important to distinguish between scientific language and philosophical/theological language. Properly speaking, when a scientist refers to evolution as "random," it means that empirically, evolution's outcome is unpredictable; for a philosopher, however, "random" may mean "without purpose or design."

The church, many of these experts said, can accept the former but certainly not the latter.

In that regard, some Catholic observers pointed to a 2004 document of the International Theological Commission, the main advisory body to the Congregation for the Doctrine of the Faith, titled "Communion and Stewardship." Paragraph 69 of the document treats the distinctions among different meanings of words such as "unguided" and "random."

Scientists debate, the paragraph said, whether life's development is best explained by explicit design or random mutation and natural selection. This is not an argument that theology can settle. Following Thomas Aquinas, however, the document says that divine providence is consistent with either hypothesis. God's causation can express itself through both necessity and contingency, so that even if the development of life seems random to empirical observation, it certainly doesn't to God.

I had hoped to speak to Schönborn about all this, but unfortunately he was in Poland as I wrote the piece. This week, however, I was able to reach him. My question was, what does he make of paragraph 69 of the ITC document? In the end, is his problem with evolutionary theory itself, or with its potential philosophical and theological abuse?

This is his response:
"I agree completely with what was formulated in number 69 of 'Stewardship and Communion.' And I feel confirmed in my convictions by this document. In any case I think it is necessary to cite the whole paragraph 69, when it states: 'In the Catholic perspective, neo-Darwinians who adduce random genetic variation and natural selection as evidence that the process of evolution is absolutely unguided are straying beyond what can be demonstrated by science.'

"For Catholic thinking," Schönborn told me, "it was clear from Pius XII's encyclical, Humani generis, that evolutionary theory can be valid to understand certain mechanisms, but it can never be seen or accepted as a holistic model to explain the existence of life."

Schönborn's point thus seems to be that in "absolute" form, meaning as a "holistic model" that would exclude design as a metaphysical matter, "evolutionism" turns into a philosophy that parts company with Christianity.

In that light, observers say, Schönborn's view does not seem to court a new Galileo affair, putting the church at odds with scientific discoveries. He's making a philosophical point, not a scientific one. In the end, he's warning that Christianity cannot accept a universe without God, and it's fairly difficult to argue with that.
