Did God Create the World in Six Days? How Should We Read Genesis?
A Question That Worries People
For many Christians, the opening chapters of Genesis are a battleground. On one side are those who insist that the world was made in six twenty-four-hour days a few thousand years ago. On the other are those who say science has shown the whole story to be myth. Caught in the middle, many ordinary Catholics are unsure what they are supposed to believe.
The Catholic Church has never taken either extreme. She teaches that Genesis is the inspired word of God and tells us true and essential things about God, the world and ourselves. She also teaches that it must be read for what it is, and that it was never meant to answer the questions modern science asks.
Read It the Way It Was Written
Every part of the Bible has to be read according to its kind of writing — what scholars call its literary form. Poetry is not read like history, and a parable is not read like a law code. The Second Vatican Council asks readers to pay attention to the forms of writing in use at the time, so as to understand what the sacred author really meant to say (Dei Verbum 12).
The opening chapters of Genesis are not a scientific report, and they are not a myth in the sense of a made-up story. They are a carefully constructed account, using rich imagery and a deliberate structure, to teach profound truths. The Catechism notes that the account of the Fall uses figurative language but affirms a real event that took place at the beginning of human history (CCC 390).
What About the Six Days?
The Church does not require Catholics to believe that creation took six twenty-four-hour days. This is not a modern concession. Long before modern science, Christian thinkers recognised that the “days” might not be literal. St Augustine, writing around the year 400, thought God might have created all things at once, and that the six days were a way of presenting creation in an orderly fashion for our understanding. In 1909, the Pontifical Biblical Commission confirmed that the Hebrew word for “day” in Genesis 1 may be understood either as an ordinary day or as a longer period of time.
Look closely at the structure of Genesis 1 and you can see its design. In the first three days God creates spaces: light and darkness, sky and sea, land. In the next three He fills them: sun, moon and stars; birds and fish; animals and man. On the seventh day He rests. The pattern teaches that God is the author of all order, and it gives the sabbath its meaning.
What We Must Believe
If the Church allows freedom on the days, what does she require? Several truths are essential.
God created everything from nothing. Before creation there was no raw material, no eternal matter, no rival power. God alone is eternal, and everything else exists because He freely chose to bring it into being. The Church has taught this solemnly (Fourth Lateran Council, 1215; CCC 296).
Creation is good. Again and again Genesis says, “God saw that it was good.” The material world is not evil, not an illusion, not a prison for the soul. It is God’s good gift.
God holds all things in being. Creation is not only something that happened long ago. God continually sustains everything in existence. If He ceased to will it, it would cease to exist (CCC 301).
Human beings are made in God’s image. Man and woman are the summit of creation, made “in the image of God” (Genesis 1:27), with reason, freedom and the capacity to know and love their Creator.
Each human soul is created directly by God. Whatever the history of the human body, the Church teaches that every individual soul is created immediately by God. It is not produced by our parents, nor by any natural process (CCC 366).
There was a real Fall. The story of Adam and Eve affirms a real event: our first parents, created in friendship with God, turned away from Him by their own choice, with consequences for all humanity. See What Is Original Sin, and Why Does It Affect Us?
What About Evolution?
The Church does not reject the theory of evolution as a scientific account of how living things developed. In 1950, Pope Pius XII’s encyclical Humani Generis allowed Catholics to study the possibility that the human body developed from earlier living matter, while insisting that the soul is created directly by God. Later popes have spoken respectfully of the scientific evidence for evolution.
At the same time, the Church rejects any version of evolution that claims the universe has no purpose, that it came about by blind chance alone, or that human beings are nothing more than animals. These are not scientific conclusions. They are philosophical claims, and they go beyond what science can show.
There are real questions here that theologians continue to discuss, especially about how the biblical account of our first parents fits with scientific findings about human origins. Humani Generis insisted that the truth of original sin must be safeguarded in any theory of human origins. Catholics can explore these questions with an open mind, confident that the truth will not contradict itself.
Faith and Science Are Not Enemies
The Church teaches that faith and reason cannot truly contradict each other, because the same God gave us both the light of reason and the gift of revelation (CCC 159). If a scientific finding seems to clash with the faith, either the science has been misread or the Scripture has.
Many great scientists have been devout Catholics. The theory of the Big Bang was first proposed by a Belgian priest, Fr Georges Lemaître. Science studies how the world works. Faith tells us why there is a world at all, and what it is for. These are different questions, and both are worth asking.
What Genesis Is Really For
When we fixate on how long creation took, we can miss what Genesis is actually saying — and it is saying a great deal. There is one God, not many. He is good, and so is His creation. The sun and moon are not gods to be worshipped but lamps He has made. Human beings have a unique dignity, made in His image. Work and rest both have their place. And evil is not part of God’s design but entered through human freedom.
These were radical claims in the ancient world, and they remain the foundation of how Christians see everything. Genesis does not answer the questions of a scientist. It answers the questions of every human being: Where do I come from? Why am I here? Why is the world the way it is? Those answers are the ones that matter most.
