Anthony here with another long post, this time about a hot topic: evolution.
We all know how it goes. Protestants thump their Bibles and declare that evolution isn't in scripture. Atheists thump their biology textbooks and declare that scripture isn't scientific. “Faith!” screams one side, and “Science!” screams the other. And so it seems to most of the world that faith and science are opposed, and you have to pick a side. And good protestants take their kids on field trips to the Creation Museum, and good atheists insist their kids watch Cosmos, and the debate gets more and more shrill.

Where do Catholics fall in all this? Most Catholics take one of two rather worrying paths. Liberal Catholics embrace evolution because then they can talk about Teilhard de Chardin’s “noosphere” and how God is evolving along with us and ignore traditional doctrine. Conservative Catholics reject evolution because it seems to lead to either that nonsense or to atheism, and so they follow the protestants. Homeschooled Catholic children read protestant science textbooks, and they visit the Creation Museum too.
But some interesting facts are obscured in all this. One is that the Big Bang theory, supposedly a bastion of atheism, was first posited by
a Catholic priest.

Another is that St. Thomas Aquinas intriguingly wrote, “[S]pecies, also, that are new, if any such appear, existed beforehand in various active powers; so that animals, and perhaps even new species of animals, are produced by putrefaction by the power which the stars and elements received at the beginning”
(Summa Theologica, I.73.1 reply 3). Species coming into being through natural causes? That sounds suspiciously like something near to evolution, from the pen of the man who is most famous for his proofs of the existence of God.
So what’s going on here?
Let’s first of all look at the common atheist refrain: “Evolution is true, so God doesn't exist.” Can you spot the problem with it? Here’s a hint: if you said, “The problem is that evolution is not true,” you’re making the same mistake many religious people make. You’re attacking the wrong premise.
Let’s break the atheist claim down into a syllogism:
Evolution is true.
Therefore, God does not exist.
Something is missing here. We only have one premise before the conclusion, and we need at least two. But we do have a second premise; it’s just implied. Let’s re-write the syllogism using that premise as well:
If evolution is true, God does not exist.
Evolution is true.
Therefore, God does not exist.
This is a lot clearer, isn't it? Now we can see the problem. Protestants try to disprove the conclusion by saying that the second premise isn't true. But that grants the first premise to the atheists. And in fact it is that first premise that is the problem.
What does evolution have to do with God? Atheists say evolution gets rid of the need for a Creator, since we can see how one species evolved to the next and how the universe developed. Protestants say that evolution contradicts Genesis, which states that God created the universe over a period of six days.
Both of them are misunderstanding what creation actually means.
In his commentary on Genesis, Thomas Aquinas talks about the order of creation and at the same time gives us an explanation of how to read the Bible:
“For certain things are per se the substance of the Faith, as that God is three and one, and other things of this kind, in which no one is authorized to think otherwise. . . . But certain things [pertain to the faith] only incidentally [per accidens] . . . and these things can without danger remain unknown by those who are not held to be knowledgeable about the Scriptures, for example, many items of history. In these things even the Fathers have thought differently and have explained the Scriptures in different ways."
Aquinas is saying that what the Bible teaches can be divided into things that are of primary or doctrinal importance, like the Trinity, and other things, like history and science, that are only incidental to the faith and that the Bible is not concerned with teaching. This contradicts a protestant reading, which sees every line of the Bible as having equal weight and being true in a literal sense (though, strangely, their literal understanding of scripture breaks down at John 6 – but that’s a post for another time). Aquinas is basically saying that the Bible is not a science book. Your faith will not be affected if you don’t understand the order of creation, but it will be affected if you reject the fact that the world was created.
This is important. It means that, though the literal meaning is always the first meaning to look for, the Bible is allowed to operate on other levels. It does not rule out metaphorical or symbolic speaking, as, for instance, when Psalm 103 says that God "makest the clouds thy chariot: who walkest upon the wings of the winds." He’s obviously not doing that literally.

And it frees the Bible from trying to be not only a source of religious truth but also a science book, a history book, and so on. This is important because while the New Testament is a straightforward historical text, the Old Testament can be
weird, man
, weird. It’s a collection of myths – not in the sense of being untrue, but in the sense of a story that tells important truths but is not an exacting and rigorous historical document that is literally factual down to its tiniest incidental details. It's stories the Hebrews told to make sense of things -- real things -- that they experienced. So the Old Testament is always attributing ideas and motivations to God that can't be literally true. For instance, does anyone (except radical Calvinists, of whom I have met one) really believe that God hardened the Pharaoh's heart and then punished him for it, as it says in Exodus?

And what about Exodus 32:14, which says, "And the Lord was appeased from doing the evil which he had spoken against his people?" God can neither do evil, nor change his mind. Taking every jot of the Old Testament literally can lead you to some very strange places. This doesn't mean that you can interpret everything in the Old Testament as being nonfactual if you don't like it (or if it doesn't fit with the prevailing political theory of the day), or say, "Oh, those Hebrews, how quaint." It just means that not everything in the Bible is a statement of doctrine.
Aquinas goes on,
"So, therefore, with regard to the beginning of the world, there is something which pertains to the substance of the Faith, namely, that the world was created to begin with. And this all the Fathers agree in saying. But how and in what order it was made does not pertain to the Faith except per accidens, inasmuch as it is presented in Scripture, the truth of which the Fathers retained in their varying explanations as they arrived at different conclusions.”
He's saying that Augustine and the other Fathers differ in how they interpret the order of creation. Most Fathers interpret it literally, but Augustine thought that the order set forth in Genesis wasn't an order in time but a grouping of categories. Things that are more fundamental are mentioned first, but that doesn't necessarily mean that they were created first in time. That's a radically different reading than the literal sense, but Aquinas likes it. He goes on to write that the other Fathers' interpretation of the order of creation as a chronological sequence of events is “seemingly more in keeping with the surface of the literal sense.” But Augustine's opinion that the order in Genesis is not chronological “is more reasonable and defends Sacred Scripture more from the derision of non-believers, a factor which Augustine, in his Letter of Genesis (bk. I, ch. 19) teaches us is to be kept well in mind, so that the Scriptures may be expounded in such a way that they not be mocked by nonbelievers. This opinion pleases me more.”
So you see, while the Fathers agreed on the fact of creation, they disagreed as to the order, and Aquinas did not see a problem with this. The fact of creation belongs to doctrine. The order does not.
Actually, Augustine didn't think the day of creation were literal; rather, creation happened in a single instant, and the "days" of creation represented the understanding of creation as it was revealed to the angels (I can't help but think of Tolkien's Ainulindalë when I read this interpretation). Aquinas thought that a process of creation taking six 24-hour days was probably true (though he had no problem with interpreting it as longer spans of time, or in a different order) but he also believed that Augustine’s emphasis on creation being accomplished all at once was correct.
Wait. On the one hand we have creation as a process over time. On the other hand we have creation being accomplished all at once. Don’t those contradict?
No, because we aren't using the word in the same way for each.
This brings us to the heart of the matter: what is actually meant by creation.
Aquinas makes this point: “
Creatio non est mutatio.” Creation is not a change.
Creation is not the kind of cause and effect we see in nature, which is always a change from one thing to another. It’s not a tree creating acorns, or humans making other humans. It’s not a potter changing clay into a pot, or an artist painting a portrait, or a novelist writing a novel.

| Change. Not creation. |
Even though we use the word “creation” for these things, we use the word only analogously; they are not the same kind of thing as the creation of the universe by God. The creation of the universe is creation “
ex nihilo,” from nothing. It is not a change from one thing to another, but a completely different, completely radical kind of causation.
For clarity, from here on I will refer to the everyday, natural kind of creation (making something new out of something that already exists) with a little “c,” and God’s radical causation of the universe (creation from nothing) with a big “C.”
Aquinas believed that even if what we might call the Genesis “process of creation” took time – whether that time was is six days or 13 billion years – still Creation itself, as the radical causation of the universe from nothing, was an all-at-once deal. But even that language is deceiving. “All at once” doesn’t mean “at a moment in time.” For one thing, Creation also creates time itself. And so Creation is not simply a moment in time at the beginning of everything. Rather, everything that is created is dependent at every moment (and even the moments themselves are dependent) upon God for its existence. Creation properly defined is the radical dependence of all things upon God for their very being.
Augustine in
The Literal Meaning of Genesis writes:
“In the first instance God made everything together without any moments of time intervening, but now he works within the course of time, by which we see the stars move from their rising to their setting, the weather change from summer to winter . . . For the power and might of the Creator, who rules and embraces all, makes every creature abide; and if this power ever ceased to govern creatures, their essences would pass away and all nature would perish. When a builder puts up a house and departs, his work remains in spite of the fact that he is no longer there. But the universe will pass away in the twinkling of an eye if God withdraws His ruling hand.”
So we see that big C Creation is the radical dependence of all creation on God for its existence. It’s not six days of time, nor even strictly speaking a single moment of time; it is the giving of being by God to everything that he created, and so it is not time-bound at all.
But if this is true, why does Genesis talk about six days of creation? Augustine goes on,
“God moves his whole creation by a hidden power and all creatures are subject to this movement: the angels carry out his commands, the stars move in their courses, the winds blow now this way now that, deep pools seethe beneath tumbling waterfalls and mists form above them, meadows come to life as the seeds put forth grasses, animals are born and live their lives according to their proper instincts, the evil are permitted to try the just. It is thus that God unfolds the generations which he laid up in creation when he first founded it; and they would not be sent forth to run their course if he who made creatures ceased to exercise his provident rule over them."
In other words, God “unfolds the generations,” via natural causation. Natural causation is a real thing. When a bird soars through the air, its flight is natural. Its wings are shaped for flight, its muscles move those wings in just the right way to catch the air, the air is molecularly structured in such a way as to be able to hold the bird in motion between earth and sky. But it is God who keeps the bird itself and the natural laws that govern its flight and the movements of its muscles and the flowing of its blood and the structure of the air and the entire system of cause-and-effect in existence at every moment. He underlies it, upholds it,
creates it, holds it in being. It is caused naturally. It is caused by God. They are different kinds of causation. Neither rules out the other.
This is important. If we do not have a proper understanding of God’s causality and natural causality, we can fall into the same error in one of two ways, depending on whether we are religious or atheist. The first way is what the Muslims fall into. Their idea of God’s causation is that God directly causes everything, and natural causation is an illusion. As philosophy professor Dr. Michael Tkacz so colorfully put it, “When a camel poops in a tent, that’s not the camel pooping. That’s God doing that.”

Atheists fall into the same error in another way. They point to nature and say, “We can explain why these things happen naturally, therefore there is no need for God.” But St. Thomas would respond, “Why does nature exist? Where do the rules that govern it come from? If everything relies on something else to explain its existence, as we see in nature, how could anything at all exist? There must be something that exists outside of the natural order, something which does not rely on anything else, that never came to be but always Is. This is the ground of all other being.”
Can you see where we are going with this? Given this Catholic understanding of natural causation and God’s Creation, is evolution a problem?
Natural causation is real, and yet it is also dependent upon and indeed is itself caused by God. Every natural process is both natural (that is, explainable in terms of natural cause and effect) and dependent upon God (who explains the whole system of natural cause and effect). This is true of the growth of a tree from acorn to oak. Why should it not be true of the universe itself?
And in fact Genesis supports evolution more than you might expect. Since we know that Big C Creation is not a process in time at all, why does Genesis talk about "days" of creation? When God creates from nothing it doesn't take him time. He doesn't even exist in time. So the days of creation probably don't mean repeated instances of specific, from-nothing creation (that seems a pointless way for God to act), but rather the “unfolding of generations,” the little c creation of new things from “the power which stars and elements received at the beginning.” Remember, just because something is natural doesn't mean God isn't causing it; his is a more fundamental way of causing.
For that matter, if God is going around creating individual things from nothing, why is man exempt? Genesis says that God created man from the earth. Did he create man from the earth but the plants and animals by special from-nothing creation? That isn't very consistent.
Concerning the length of the days of creation, why would God bind himself to our invented human time classification, especially before the creation of the sun and earth by whose motion we measure hours and days? It is more likely that the days of creation denote simply a period of time, not strict 24 hour segments.
For that matter, why was light created before the sun? The Hebrews, like all ancient civilizations, thought of the sun as the greatest light source in the universe, and yet Genesis talks about light coming before it, before any source at all. That doesn't fit any ancient cosmology. But it does fit rather well with the Big Bang.

But if all this is true, what of the atheist claim that evolution is completely godless? Well, that’s exactly the claim we need to attack, not the claim that evolution is true. See, atheists are not content only with the scientific theory of evolution as a natural process. They graft a philosophy onto it, a philosophy called metaphysical naturalism, or, by its detractors, scientistic materialism. This is the belief that the only things that exist are material things that we can study with the scientific method (they believe science is the only valid form of knowledge, hence the word scientISTIC, not to be confused with scientific). They claim that there is no transcendent purpose or meaning to the universe; everything is pure chance. These are not scientific claims. They are philosophical claims. We need to call them out on it and demand that they disentangle their philosophy from science.
So the next time an atheist brings up evolution to debunk God, shrug and say, “So?” Don’t waste time and open yourself up to defeat by accepting their premise that evolution disproves God. Don’t fight the battle on their ground. Instead, hit them with St. Thomas.

Ex nihilo nihil fit, baby. Ain't no way around it.
And don't go redefining "nothing." I'm looking at you, Krauss. |
(Important note! When I say that evolution is not godless I don't mean I believe in what is called “Intelligent Design.” Intelligent Design theory holds that God reaches into the natural order and tweaks evolution to go where he wants. But he doesn’t need to do that. He underlies the natural order. He upholds it. It is what it is because of him. The idea that he needs to tweak it accepts the atheist view of the natural order as something that is not dependent on God but independent, such that it runs by itself and he needs to adjust it. That relegates God to just another being alongside of nature, even if a very powerful one. And it means that the natural order doesn't have the foundational, transcendent cause that it must have to exist at all.)
Always remember Thomas Aquinas’ distinction between primary (doctrinal) matters in scripture, and secondary matters. Here's a little more from Augustine:
"In matters that are so obscure and far beyond our vision, we find in Holy Scripture passages which can be interpreted in very different ways without prejudice to the faith we have received. In such cases, we should not rush in headlong and so firmly take our stand on one side that, if further progress in the search for truth justly undermines our position, we too fall with it."
But what about those liberal Catholics who follow Teilhard de Chardin? Isn't evolution part and parcel with their heterodoxy? I've experienced this, actually. Jesuit priests at my undergrad interpreted the doctrine of Original Sin in such a way that it was unrecognizable. Instead of an actual transgression by an actual human being, the consequences of which are inherited by his descendents, they see it as what they call "systemic sin;" it is simply a feature of the universe that bad things can happen. (This belief means that they can no longer have a proper understanding of the Redemption, which in turn means that they no longer understand the sacrifice of the mass correctly, or the Real Presence . . . it's a heckuva mess.) They taught this because evolution seems to deny that there were two first parents from whom the whole human race descends, and it also claims that death was a part of creation from the beginning, seeming to undermine the doctrine that Original Sin brought death into the world. So yes, in large part because of evolution these Jesuits descended into heterodoxy. But evolution doesn't have to lead us to such conclusions. I don't have time to go into it here, but Edward Feser, that awesome Thomistic philosopher, has given a very good two-part breakdown of the question
here and
here.
We do need to be careful not to extend evolution to theology, as Teilhard de Chardin did. Even if bodies evolve it doesn't mean that consciousness evolves or that human nature itself is always rising and improving and didn't suffer a fall. Yes, I know that Benedict XVI has quoted Teilhard de Chardin. But he's dangerous. You
might be able to squint and interpret him in something like an orthodox fashion, but the Jesuits at my undergrad sure didn't. They were out-and-out heretics. So are the nuns of the LCWR.

| “Let us evolve the church through a mystical presencing, solidarity with Earth, building community as “whole-makers,” genius for cooperative self-governance and decision making, and bringing love and hope for the future into the lives of millions as we evolve consciously as a new whole planetary system.” |
As Pius XII made clear in
Humanae Generis, we can talk about evolution, but when it comes to theology, "all [must be] prepared to submit to the judgment of the Church, to whom Christ has given the mission of interpreting authentically the Sacred Scriptures and of defending the dogmas of faith."
Now, does all this mean I believe in evolution? Not necessarily, at least not in biological macroevolution, but that's because it doesn't seem to add up scientifically, not because I'm scared it steps on my faith's toes. What I don't understand is how something that is only beneficial to an organism in a perfect, complete form, like the ability to fly or a spiderweb, could evolve through natural selection. I also don't understand how life could evolve from non-life. There are a lot of gaps in evolutionary theory, and it sometimes seems to me as if atheists ignore them because they believe that evolution has to be preserved in order to disprove God. But if someone could explain these apparent gaps to my satisfaction, I would accept them. The point is, if evolution is false, it doesn't matter. If evolution is true, it doesn't matter.
It doesn't matter.
So don't waste time attacking evolution. Hit them with St. Thomas instead.
And let there be light.
