"Those distinct substances, which concretes generally either afford, or are made up of, may, without very much inconvenience, be called the elements or principles of them.”
― Robert Boyle, The Sceptical Chymist
"A common sense interpretation of the facts suggests that a super-intellect has monkeyed with physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature. The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question."

"Through his Word and wisdom he created the universe, for by his Word the heavens were established, and by his Spirit all their array. His wisdom is supreme. God by wisdom founded the earth, by understanding he arranged the heavens, by his knowledge the depths broke forth and the clouds poured out the dew."
--St. Theophilus of Antioch, Letter to Autoylcus
Evolution: "The process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth." --Oxford English Dictionary (OED)
Evolution: "The gradual development of something."--OED
INTRODUCTION--EVOLUTION--IS IT TRUE?Evolution--is it true? A few weeks ago an email was forwarded by Father Robert Spitzer's Magis Institute (I'm on the Academic Advisory Board).to me for comment The correspondent--let's call him "John Doe"--insisted that evolution violated Catholic Teaching, was in fact heretical, and cited the following pronouncements of the Ecumenical Councils, Lateran IV, Vatican I and of Pope Pius XII's encyclical, Humani Generis, to support his claim.
"God…creator of all visible and invisible things, of the spiritual and of the corporal; who by His own omnipotent power at once from the beginning of time created each creature from nothing, spiritual and corporal, namely, angelic and mundane, and finally the human, constituted as it were, alike of the spirit and the body." [emphasis added by John Doe]--Lateran IV (D.428).
"If anyone does not confess that the world and all things which are contained in it, both spiritual and material, were produced, according to their whole substance, out of nothing by God; or holds that God did not create by his will free from all necessity, but as necessarily as he necessarily loves himself; or denies that the world was created for the glory of God: let him be anathema." [emphasis added by John Doe]--Vatican I (Article 5).
"Some however, rashly transgress this liberty of discussion, when they act as if the origin of the human body from pre-existing and living matter were already completely certain and proved by the facts which have been discovered up to now and by reasoning on those facts, and as if there were nothing in the sources of divine revelation which demands the greatest moderation and caution in this question." [emphasis added, RJK]--Pope Pius XII, Humani GenerisJohn Doe agreed that "microevolution" could occur by mutation (slight changes of phenotype and genotype within a species due to mutation of genes}, but disagreed with the central tenet of evolution that all living things today descended from one primal original living thing.
GENERAL ARGUMENTS AGAINST JOHN DOE'S PROPOSITION
Here are general arguments that will be given in more detail below.
Evolution--the gradual change into different kinds from a single kind as per the second OED definition--is not limited to biological things, but to matter in general, so if evolution is forbidden for biology by John Doe's interpretation of the Council pronouncements, it is forbidden also for matter in general, and thereby is forbidden all of physics and chemistry.
The evidence for evolution of living organisms is impressive. Without going into detail, I'll cite the convincing features and also note that evolution--in the sense given by the first Oxford English Dictionary definition--is NOT the same as the proposed neo-Darwinian mechanism for evolution, which is a theory.
The Council pronouncements and the quote from Humani Generis have to be parsed very carefully to understand the full scope of the meanings of "at once" and "out of nothing"; moreover, the quote from Humani Generis must be put in context and related to other statements in that encyclical.
The position of the Catholic Church on evolution has been well stated by Pope St. John Paul II (see also "On Pope St. John Paul II's Feast Day") that evolution is a fact, but there are various theories to explain the mechanism of evolution. Neo-Darwinism is just one, and one not universally accepted even by some non-theist scientists and philosophers.
GOD'S PERIODIC TABLE AND THE EVOLUTION OF MATTER

For purposes of this discussion, I'll accept (as do most physicists) that "In the Beginning" there was a super-hot tiny ball of energy, "one thing", that changed to quarks, anti-quarks, gluons and then yielded elementary particles--protons, neutrons, electrons. Subsequently gravitation induced star formation with protons and alpha particles (helium-4 nuclei) present in early stars. There would have been a serious obstacle to further formation of the elements because a three-body collision of three alpha particles would be required for the formation of carbon-12 (the next step in formation of the elements) and as those of you who have shot pool know, the probability of a triple collision from random motion of particles is small.
Fred Hoyle (who had derisively labelled creation from a singularity as "The Big Bang"--the name stuck) saw a problem in the abundance of carbon-12 and other elements in the universe and the lack of a mechanism for their creation. He predicted an excited, higher energy state of carbon-12 nuclei that would enhance the formation of carbon-12 by the so-called "triple alpha process" (see the diagram below). His prediction was verified experimentally.

In this process, two alpha particles (helium-4 nuclei) collide to form a beryllium-8 nucleus, which is unstable. However, the likelihood of forming carbon-12 from a collision with an alpha particle is enhanced by a "resonance effect". This effect comes about because an excited, high energy level of the carbon-12 nucleus has almost the same value as the nuclear energy levels of beryllium-8 and helium-4.
Carbon-12 formation would be the bottleneck; if carbon-12 could not be formed, then no oxygen, nitrogen, or heavier elements. All these reactions take place at a very high temperature in the interior of giant stars. When these stars implode, go nova (as with the Crab nebula picture above), all the heavy elements formed in the interior are scattered through the universe for the formation of planets and living organisms.
Here's the important point to be emphasized in this: it is fundamental physics that enables the formation of the elements, the evolution of the Periodic Table, if you will. It is NOT a simultaneous creation of each element. It is a much more wonderful thing to have this occur as a consequence of "natural law", rather than an ad individuum, separate and simultaneous creation of each element. It is evolution, not creation all at once. And it is God who created the rules of physics that enables this evolution.
EVIDENCE FOR EVOLUTION OF BIOLOGICAL ORGANISMS*
Here's a question for those who propose an instantaneous creation of all species: why does the fossil record of more than a billion years ago contain indicators of only microbial species, and why do the fossil records of different geologic eras contains a progression of types, with no recent phyla (e.g. mammalia) in older records?

PARSING LATERAN IV--"AT ONCE"; "OUT OF NOTHING"
"...each one [type of creature] fulfills its proper function, comes to creatures from those causal reasons implanted in them, which God scattered as seeds at the moment of creation [emphasis added] ... Time brings about the development of these creatures according to the laws of their numbers, but there was no passage of time when they received these laws at creation.[emphasis added] --St. Augustine of Hippo, de Genesi ad Litteram (the Literal Meaning of Genesis.)
THE PRESENT POSITION OF THE CHURCH ON EVOLUTION*
“...with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter [but] the Catholic faith obliges us to hold that souls are immediately created by God.” [emphasis added]--Pope Pius XII, Humani Generis
"Pius XII underlined the essential point: if the origin of the human body comes through living matter which existed previously, the spiritual soul is created directly by God..." Pope St. John Paul II, Address to Pontifical Academy of Sciences:"On Evolution".
“And to tell the truth, rather than speaking about the theory of evolution, it is more accurate to speak of the theories of evolution. [emphasis added] The use of the plural is required here—in part because of the diversity of explanations regarding the mechanism of evolution, and in part because of the diversity of philosophies involved.
"As a result, the theories of evolution which, because of the philosophies which inspire them, regard the spirit either as emerging from the forces of living matter, or as a simple epiphenomenon of that matter, are incompatible with the truth about man..." ibid.I've given a more detailed account of this in a post, Do Neanderthals have a soul?
"Faith and reason are like two wings on which the human spirit rises to the contemplation of truth; and God has placed in the human heart a desire to know the truth—in a word, to know himself—so that, by knowing and loving God, men and women may also come to the fullness of truth about themselves."Because we do not understand at present how evolution works are we to reject it as a magnificent work by God and rely on a literal interpretation of Scripture and Medieval Councils (which required Jews to dress differently from Christians)? We don't do this for the creation of matter and the universe, for which physics gives a clearer explanation than molecular biology does for evolution. The Church today does not require that we do so; the Church requires only that we do not fall into the trap of believing materialistic theories that attempt to explain evolution.
