Before looking at theseproblems, we will need to consider what theistic evolution is, and try to sortit into its various versions. After all, different forms of theistic evolution may face differentproblems.
Keith Stewart Thomson has ahelpful discussion in The American Scientist
ThomsonÕs Definitions ofEvolution
Pattern: Change overtime. The first is a Ògeneral sense of change over time.Ó
In any case, Thomson couplesthese changes in biotic diversity with Òa parallel set of data for changes inthe earth itselfÓ[6]– the geologic record – the combination producing a pattern ofincreasing diversity and complexity from the earliest fossils to thepresent. So stated, evolutionparts company here with young-earth creationists, who see in the geologiccolumn mostly the record of a one-year flood rather than a large fraction of earthÕshistory.
But theistic evolution andold-earth creation do not divide on this matter. Thomson notes that Òchange over time is the most solidlybased fact of evolutionÓ
The divergence betweentheistic evolution and ÒBlind WatchmakerÓ evolution is whether there is a Godbehind the process. This is thesort of distinction the intelligent design movement is seeking to detect.
Process: Descentthrough common ancestry.
But this second sense is abit problematic. There are thosewho call themselves evolutionists, even in a non-theistic sense, who would notagree with common descent. For evolutionists who believe in an extra-terrestrialorigin of life, there is no compelling reason why all of it reaching earth needhave come from the same source.
If non-theistic evolutionistscan believe that modern life derived from a few simple life forms rather thanone, then theistic evolutionists need not postulate a single source either– other than God, the ultimate source – though it seems nearly allof them do. Though nearly allold-earth creationists postulate at least two independent creations (originallife and mankind), one could still be an old-earth creationist while having alllife descended from one original form. Here, too, it looks like it is the mechanism that distinguishes theisticevolution from old-earth creation, though that, too, may have some kinks weneed to investigate.
Mechanism: NaturalSelection.
And what are we to make ofÒrandomÓ variation? This willsplit the non-theistic evolutionists from the theists.
ASA Creation Statement
Considernext the statement on theistic evolution composed by Keith Miller and DavidWilcox for the Creation Statement Subcommittee of the ASA Commission onCreation. Neither their statement,nor the larger whole of which it is a part, was intended to bind the ASA orofficially reflect the exact diversity of views therein.
Statement on Creation:
Theistic Evolution (Continuous Creation, EvolutionaryCreation) View
Theological Statements:
A. In addition to the theological commitments affirmed byall parties, ASA members who accept an evolutionary* perspective, would affirmthe following:
1. God is freeto act in creation in any way consistent with His character.
2. Evolutionary processes* are not antithetical to God'screative action. Furthermore,nothing in scripture provides a theological basis for rejecting the descent ofall living beings from a common ancestor, including humans.
3. An evolutionary* view of the history of life provides apositive, productive context for understanding God's relationship to creation,and our role as His image bearers. It also provides a fruitful context for considering the meaning andimplications of Christology and the cross.
4. Christians should rejoice and praise God for each newrevelation of the history and character of the creation, for each new discoverythat fills previous gaps in our scientific understanding.
B. Areas of theological diversity among Christians holdingan evolutionary* view:
1. How does God direct the creation to His desiredends? Various models for God'saction have been proposed, of which some follow. These are not mutually exclusive, so individuals may holdmore than one.
a. God is actively directing ALLnatural processes ALL the time so that all physical events are specificallywilled by Him.
b. God gave, and continues to give,being to a creation gifted with all the capabilities to bring forth all theforms, processes, and events, willed by Him.
c. Creation responds to God's willas our bodies respond to ours. However, God's being is not embodied in creation but is transcendentover it.
d. God acts to determine theinherent indeterminacies of physical events, at the micro level of quantumphenomena and at the macro level of chaotic systems. The physical universe is not deterministic, but rather is aninherently open causal system.
2. To what extent has God granted freedom to Hiscreatures? Various suggestionshave been proposed:
a. God has chosen to limit Hisdirect control over some aspects of creation to give His creatures genuinefreedom.
b. God allows for a certain levelof genuine indeterminacy in creation such that specific outcomes are notpredetermined. At the same time,He remains sovereign and the fulfillment of His will is assured.
c. All physical events arepredetermined and preknown by God.
C. Scientific Statements:
1. An ancient and dynamically changing Earth and universe issupported by overwhelming evidence from geology, physics, astronomy, andcosmology.
2. The common descent of all living things is well‑supportedby diverse lines of evidence in geology, paleontology, biology, and genetics.
3. Biological evolution* has great explanatory power and hasproven effective in generating new and testable hypotheses in a wide range ofscientific disciplines including historical geology, paleontology, ecology,biogeography, developmental biology, biochemistry, and genetics.
4. New discoveries and new models are progressively closingmany previous gaps in our knowledge and understanding of evolutionary historyand mechanisms.* While manyunanswered questions remain, current research is raising many excitingpossibilities for studying previously intractable problems.

*The various references to evolution herein are understoodto include the full range of scientific models from the adaptive change ofspecies populations to the diversification of life on Earth from its commonorigin, but to exclude the idea of autonomous nature assumed in the
A few comments on theMiller-Wilcox statement. Undertheological statements that all theistic evolutionists agree on, both young-and old-earth creationists would also agree with A1 (GodÕs freedom) and A4(rejoicing in GodÕs revelation in nature), and many –
Among the theologicalstatements where theistic evolutionists disagree, item B1 deals withmechanism. Of the fouralternatives listed, it would appear that only B1b (fully-gifted creation) islikely to be testable scientifically. Item B2 deals with GodÕs will in relation to creaturely freedom, and thevarious sub-items correspond roughly to the Arminian (B2a), Openness (B2b) andCalvinistic (B2c) models.
Among the scientificstatements, C1 (ancient, changing earth and universe) is also accepted byold-earth creationists. C2 opts tolimit the descent of living things (on earth, at least) to a single commonancestor, which, while rather characteristic, does not seem to be necessary totheistic evolution. Regarding C3,a model may have great explanatory power and be effective in generatinghypotheses, yet not be the whole story. Atheistic evolutionists make a similar claim over against theisticevolution. C4 leads us into thequestion of filling gaps, which we will examine by and by.
Having now spent some timethinking about varieties of theistic evolution, letÕs see if we can puttogether a general definition:
Theisticevolution is a view of origins inwhich God used providential means such as mutation and natural selection as theprime or only means for producing the diversity of living things on earth.
Some varieties of theisticevolution would include diversity on the matters of (1) whether original lifewas created miraculously or providentially, (2) whether there were one or moredistinct forms of original life, and (3) whether or not there really was anoriginal pair of humans, Adam and Eve.
By contrast, we can thensuggest a parallel definition of special creation as follows:
Whether or not one likesthese definitions, they permit us to view theistic origin models as a kind ofspectrum, with the extreme views using only the one means and the moderateviews using the relevant means as the prime means. Most views held by various Christians will fallsomewhere between the two extremes.
Another approach would be todefine theistic evolution and special creation so that they are not mutuallyexclusive. For instance:
In this case the extreme positions would be Òpure theisticevolutionÓ and Òpure special creationÓ and the intermediate positions wouldinvolve a mixture of the two means.
Let us begin with scientific problems that face theisticevolution. Being a theist myself,I do not find any insuperable problem with the idea that God might be behindthe various phenomena studied under evolution. I will not here attempt to deal with problems which atheistswould bring against the view. These are often (but not always) the same as those an atheist would urgeagainst theism in general, and they are largely philosophical and theologicalin nature. Instead, I want to lookat items we could call scientific that are problematic for one or another ofthe various forms of theistic evolution over against forms of specialcreation. Or, using our alternativedefinitions, problems for more providential forms of theistic evolution overagainst more miraculous ones.
The first problem is that ofthe relative scarcity of fossils that can reasonably be considered intermediateor transitional between the major categories of the biological classificationsystem.
In any model in which therehas been the sort of change over time that we call descent through commonancestry, one would expect numerous transitions between the earlier forms ofliving things and the currently existing ones. DarwinÕs original model proposed that the changes whichoccur are very small, necessitating many intermediate steps between organismswhich are even moderately different. Employing the idea of natural selection, Darwin suggested that theintermediates would eventually be eliminated through competition with theirdescendants (and surviving ancestor-forms), so that by later times large gapswould have developed between the various kinds of living organisms.
Darwin was aware that thefossil sequence was not continuous. His solution to this problem was to suggest that the fossil record isvery fragmentary. There isobviously some sense in which this is true. At least for land-based life, only a tiny fraction of theorganisms which once lived get preserved by fossilization.
This actual fossil record wasapparently one of the reasons driving a shift from the original model of Darwin¾ in which allpopulations are slowly evolving
Partly as a result of thisproblem, Gould and Eldridge proposed a version of evolution they callpunctuated equilibrium. In thismodel, the transition from one form to another is quite rapid
The problem facing thepunctuated equilibrium view is similar to that facing evolution by largemutations ¾ the chance of getting something functional is astronomicallyminuscule. This model, however,could work rather well as a form of theistic evolution.
For versions of theisticevolution that have God using random processes, the problem remains.
Let us assume for simplicitythat all the mutations are the same length L. To cross a distance equivalent to the length of 10mutations, D = 10L. Then SQRT(N) =10 and N = 100, so it will take 100 mutation steps on average to move thisdistance. One can immediately seethat it takes much longer to cross a gap by random walk than by a guided walk.
Applying random walk toevolutionary changes, the space in which the movement takes place is not thedrunkÕs two-dimensional sidewalk nor our physical three-dimensional space, butsome multi-dimensional phase space of functional characteristics.
Michael Behe, in his book DarwinÕsBlack Box, has popularized the phraseÒirreducible complexity.Ó
BeheÕs illustration is thetraditional mouse trap, which consists of a wooden platform to hold the parts,the hammer to get the mouse, the spring to drive the hammer, the arm to holdback the hammer, the trigger to release the arm and hammer, and various staplesto attach the parts to the platform. If any of these parts is missing, the device wonÕt catch mice.
Behe suggests that a similarphenomenon is found in living organisms. He gives as examples the rotary motor that the drives the flagellum inthe E. coli bacterium, thechemical processes that initiate vision and blood clotting, and the intracelltransport system. BeheÕs point isthat such systems apparently have no survival value until the whole has beenassembled, and thus a series of coordinated mutations is needed to produce anysuch structures, the sort of thing that random processes are notoriouslyunlikely to provide. It is, ofcourse, possible to claim that each needed intermediate step must
A third type of scientificproblem for theistic evolution is what we might call the ÒshapeÓ of the fossilrecord. Darwinian evolution (andindeed, the neo-Darwinian and punctuated equilibrium versions also) buildsdiversity progressively. Onebegins with small diversity, and large diversity arises late in theprocess. Thus an original lifeform consists of a single type, which over time gradually diversifies until itsvarious varieties become distinct species, some of these species diverge enoughto become separate genera, some of the genera diversify to families, and so on,up to the level of phyla. Theresult should be that the various phyla are the last categories to be formed inthe history of life. Withoutgetting into nitpicking over the exact definition of the various levels in thebiological classification system, in the Darwinian scheme life should form asort of single tree.
As a matter of fact, thefossil record pictures life as something like a large series of bushes, withthe major body plans for the animals all being formed in the brief period knownas the Cambrian Explosion. This,again, looks much more like some sort of intervention (or at least rapid, guidedevolution) than it does like a slow, random process of small mutations.
What is natural law?
Do we as Christians knowwhich of these theistic alternatives is correct? I donÕt think so. How would we decide? I knowof no way from within the universe that we could do any experiment to make achoice between the two. The answeris thus going to be obtained from some sort of philosophical or theologicalargument, from some biblical hints, or from eschatological verification.
Actually, it doesnÕt matterfor our concern. The Bible andtheology (and philosophy) still distinguish between GodÕs providential activityand his miraculous activity, whether GodÕs providential actions are mediatedthrough a created natural law structure or not. The Bible uses the distinctive Greek terms dunamis,thauma, semeion, and teras
Much of our debate betweenold-earth creation and theistic evolution (and even among the various versionsof theistic evolution) revolves around the question of distinguishingprovidential from miraculous events; and more particularly, of inferring theone or the other for events at which no human observer was present.
Now science studies thestructures and events in nature in an attempt to discover natural laws whichgovern these phenomena. Naturalevents will presumably operate continuously on some scale, so that a scientisttends to fill all gaps with interpolations which are as smooth as possible. Butactual observations are discontinuous, a series of discrete dips into thestream of nature. How do we tellwhen we have correctly or incorrectly filled a gap in the data, whether bypostulating the correct continuity or the actual miracle which has occurred, orby mistakenly postulating a continuity (or a wrong continuity) or a miraclewhen none has occurred?
Every human being isconstantly filling gaps in his or her experience, either with naturalexplanations or with miracles
I believe we are correct inseeing miracles as much rarer phenomena than providential events.
We turn now to theologicalproblems facing theistic evolution, under which we include exegetical andhermeneutical problems.
It seems to me that Genesis 1(understood from an old-earth perspective) presents no problems for some sortof theistic evolution of living things. The land produces vegetation, the waters teem with living creatures, thebirds fly in the sky, the land produces living creatures
The King James translationÒafter their kindÓ has regularly been taken to indicate fixity of species (orat least of created kind). But theword ÒafterÓ in this context is probably an archaic English usage, meaningÒaccording to,Ó as indicated by the use of the phrase elsewhere in theBible. In any case, thecorresponding Hebrew phrase lemin
The situation is different inGenesis chapter two. On the faceof it, the chapter narrates the creation of Adam by a miraculous rather than aprovidential process. Adam isÒformedÓ from Òthe dust of the ground,Ó God Òbreathed into his nostrils thebreath of life,Ó and as a result Òthe man became a living being.Ó
The idea proposed by sometheistic evolutionists ¾
The creation of Eve inGenesis 2 is clearly narrated as subsequent to that of Adam, after he had namedthe animals and come to realize that he had no mate like they did.
The fall of mankind into sin in Genesis chapter threelikewise seems problematic for at least some versions of theisticevolution. The event is narratedas though it were a specific historical event, involving two human individualswho make specific successive choices to disobey God
I see no problems in Genesis2 and 3 for those versions of theistic evolution in which Adam and Eve areseparate special creations not descended from any pre-existing life.
On the other hand, I do seeserious problems with Òno AdamÓ theistic evolution. In these versions, there never is a single pair who are thefirst humans. Instead a wholepopulation of anthropoid apes gradually develops into humans over the course ofmany thousands of years. In such acase, the narratives of Genesis 2 and 3 cannot be historical, in contradictionto the natural reading of the many references to Adam, Eve and the fall thatoccur elsewhere in Scripture. Rather the accounts in Genesis are mythical or parabolic in some sense
Let us move on to considerhermeneutical questions. What isthe genre of Genesis 2 and 3? Forthe various forms of special creation (whether young or old earth), thesechapters are fairly straightforward historical narratives, which thus form acontinuum with the remaining chapters of Genesis. They doubtless contain figurative language.
For the various forms ofÒAdam-typeÓ theistic evolution these chapters are likewise historicalnarratives, but Òformed from the dustÓ (2:7) is taken as a condensed andconcrete expression for a long process of evolution.
The term ÒmythÓ has a ratherwide range of meaning, but common to all of these is the idea that the eventnarrated never actually happened. Bible believers are rightly unhappy with this characterization ofbiblical narratives, though examples in Scripture have been suggested thatmight fall into this category. More below when we discuss parable or allegory.
There is probably littlesense in trying to distinguish parable from allegory in Scripture.
The passage is a parable orallegory for the relation between Jerusalem and God. JerusalemÕs history is parabolically narrated as the storyof a girl from her birth through much of her adulthood.
á The childÕs parents arementioned (16:3, 44-45).
á She is abandoned atbirth (16:4-5).
á God rescues her,allowing her to survive to maturity (16:6-8).
á She is adopted by God,married to him and cleaned up (16:8-9).
á God gives her many giftsof the sort appropriate for a wealthy woman (16:10-13).
á Her fame, due to herbeauty and wealth, spreads far and wide (16:14).
á She begins to trust inher beauty and wealth, turning from her husband to become a prostitute,lavishing his gifts on others and killing her own children (16:15-34).
á Therefore, God is goingto bring disaster on her, using her former lovers to bring judgment, shame andpoverty, but this will not be fatal nor final (16:35-43).
á Jerusalem is like hermother, who despised her husband and children, and like her sisters, though sheherself is the worst of the lot (16:44-59).
á But one day, God willremember his covenant with her, and restore her, and make her sisters to be herdaughters (16:60-63).
What reason might we have tothink the genre of Genesis 2-3 is that of Ezekiel 16? On the positive side, we see an example of a narrative thatboth resembles and is also quite different from the reality it is intended topicture. That is what no-Adamtheistic evolutionists claim for Genesis 2-3 over against what really happenedin the origin and rebellion of mankind. In both Ezekiel and Genesis an individual is used to represent acollective identity, Jerusalem or mankind. We donÕt know enough of the history of Jerusalem to know howto relate many of these features, but we know Jerusalem existed for centuriesbetween its birth and its adoption by God to be the capital city ofIsrael. That, after it becameIsraelite, it grew to be very wealthy in the time of David and Solomon, and itsinhabitants began to play up to the pagan nations around them and to adopttheir idolatrous practices. That,by the time of Ezekiel, Jerusalem was in real trouble from theBabylonians. That afterwards,Jerusalem was conquered, devastated, and abandoned, only to be rebuilt in amuch more humble style long afterwards. Some of the items seem to be predictions to be fulfilled at the end ofthe age. Both Ezekiel and Genesisuse rather striking figures in the story to represent something different inthe reality. In Ezekiel, therescue of an abandoned child and her subsequent marriage is used to pictureGodÕs protection of pre-Israelite Jerusalem and his subsequent taking of thecity to be his capital. InGenesis, the molding of clay and breathing into it is a vivid picture for GodÕsguiding evolution to develop apes into humans. Much more of this sort of comparison could be developed, butI will let proponents of this view do it themselves.
Negatively, there areindicators in Ezekiel 16 that it is a parabolic narrative, indicators of thesort we do not find in Genesis. For instance, Ezk 16:2-3 says, ÒSon of man, confront Jerusalem
In Genesis, we could take thenames of Adam and Eve as allegorical, but there are no explicit indicators thatwe should do so. We do have theman called Adam, which could be ageneric name, though it is not the common noun for man, Ish
The Ezekiel narrative shiftsback and forth between literal features of Jerusalem and figurative features ofthe story. The original readersare assumed to be able to handle this because they know a good deal about thehistory of the city. In Genesis,by contrast, we donÕt know the Òreal storyÓ until it is discovered by modernanthropologists, so the readers would be pretty much in the dark until now.
Could Ezekiel 16 be a modelfor the genre of Genesis 2-3? Ithink it could, but the warrant for reading it as such would have to comealmost totally from general revelation in nature. I do not think the scientific case for a gapless evolutionis strong enough to warrant our making the paradigm shift.
In recent years Howard VanTill has proposed a version of pure theistic evolution (according to my chart,page 6) which he labels Òfully gifted creation.Ó
It seems to me this viewshould be testable. Do we havegood reason to believe that nature contains the information necessary toconstruct the complex structures we see in living things, especially inhumans? Where is it?
If Van Till is an orthodoxChristian, he does not deny the historicity of the miracles narrated in thebiblical account. In this senseVan Till does not have a deistic world view, though some have accused him ofit. Yet Van Till does restrictmiracles to salvation history, removing them from the events of creation.
This reminds me of
No doubt if we picture God asa watchmaker and the universe as his watch, we would think his creation muchmore elegant if it kept time without his having to open the back every few daysto make adjustments! But supposeGodÕs creation is a violin he made on which to perform a concerto, and thatGodÕs interventions are crucial parts of his playing the music, like a seriesof pizzicatos in the midst of regular bowing. We donÕt fault Stradivarius for not being a watchmaker.
Let us suppose with Van Tillthat GodÕs miracles are restricted to salvation history.
Whether or not creation is apart of salvation history, Job 38:7 suggests that the angels were present atthe creation of the earth. Perhapsthe miracles in creation were intended for their benefit.
By the way, it does not seemto me that any of the current Christian views of creation have done much withthe question of whether and how the angels may have been involved in GodÕscreative work. This is nothingthat secular science is going to want to investigate, but Christians surelyshould give the matter some thought.
Somewhat related to thematter of creation models is the mind-body problem. Space forbids any extensive discussion of this matter, but afew questions are in order. Howdoes the mind relate to the body? Is the mind merely some sort of signal moving around in the hardware ofthe brain? Or is themind/soul/spirit some sort of ghost in the machine? Is the brain, as Sir John Eccles suggested, a machine thanonly a spirit can operate?
The mind-body interaction isalso a paradigm for intelligent design. As I see it, the intelligent design approach affirms that intelligenceis not reducible to either natural law or random (chaotic, chance)phenomena. Unlike chance,intelligence is not meaningless, but is characterized by purpose and goal.
Similarly it seems that themind-body interaction is to some extent a model for the interaction of God withnature. Just as our unseen mindcontrols the events of our visible body, so the unseen God controls visiblenature. As the unseen mind is (insome limited sense) transcendent over the body, so God is (without limit)transcendent over nature. Thereare, of course, features in the mind-body interaction which do not correspondto those in God-nature, but that is merely to say that we humans are made inthe image of God but are not gods ourselves.
Under scientific problems, we suggest the following.
Among theological problems,we suggest the following. Theaccount of human origins in Genesis 2, taken as a historical account ratherthan myth or allegory, is a severe problem for all no-Adam versions of theisticevolution, and a lesser problem for most versions of theistic evolution whichhave a non-human ancestor for Adam. The account of the origin of human sin and death in Genesis 3, taken asa historical account rather than myth or allegory, is a severe problem for allno-Adam versions of theistic evolution. The warrant for reading Genesis 2 and 3 as myth or allegory comes fromoutside Scripture, allegedly from the gapless nature of evolution. This is anexample of ÒGod of the gapsÓ thinking in which natural law is the gapplugger. We should not mistakeresearch agendas for empirical results. ÒOne who puts on his armor should not boast like one who takes it off Ó(1 Kings 20:11). The desire tohave a non-interventionist origin of humanity leads naturally to a monisticview of human nature, raising severe problems for post-mortem survival, adoctrine clearly taught in Scripture.
