"In the beginning was the Word": creation by God's word
AD 90· Idea
Faith & beliefA religious or spiritual view held by many; not a scientific claim and not testable.
The teaching of Judaism, Christianity and Islam that God created the universe by speaking: an act of will and reason, from nothing.
See it on the Science map →How it works
Genesis 1:1 opens 'In the beginning God created the heaven and the earth', and in 1:3 'God said, Let there be light: and there was light.' John 1:1, written about AD 90–100, begins 'In the beginning was the Word', using the Greek logos: word, reason, order. John 1:3 adds 'All things were made by him.' The Quran (2:117) says that when God decrees a matter, He says to it 'Be', and it is. Christian doctrine holds creation was from nothing (ex nihilo).
Why it matters
It helped shape how modern science began: Kepler, Newton and others expected an orderly, lawful universe because they believed a rational Creator made it.
What science can and can't say
This is faith, and science cannot test it. Georges Lemaître, a Catholic priest and the Big Bang's originator, held that physics neither proves nor disproves creation. Believers see the universe's order and beginning as fitting, not as proof.
Still a mystery
Theologians debate how a timeless God relates to a universe in time, and whether 'creation' means a first moment or the ongoing fact that anything exists at all.

▸The first-cause argument is identified with God in "In the beginning was the Word": creation by God's wordFaith & belief
The relationship
The argument by itself yields only an uncaused first cause, not a personal God. Aquinas ends each of his Five Ways by saying this is what everyone calls God. The Abrahamic faiths identify that cause with the Creator of Genesis and John 1, who acts by word and will: a cause that is also a mind with purpose.
How the link was found
Aristotle's unmoved mover (about 350 BC) was not a creator. Jewish, Islamic and Christian thinkers, including al-Ghazali, Maimonides and Aquinas (11th–13th centuries), fused the idea with scripture's Creator.
Is it proven?
The identification is a matter of faith and theology. Philosophy can debate the reasoning, but no observation could check it. Critics point to the gap between 'a first cause' and the God of scripture.
Open questions and mysteries
Why must a first cause be one, personal and good? Theologians answer with further arguments and revelation; skeptics find the leap unjustified.
▸"In the beginning was the Word": creation by God's word says yes, by God's word, to Did the laws of physics come first?Faith & belief
The relationship
In this view, order comes before matter. God's word, the logos (reason, order), sets the rules, and the world follows them. Early modern scientists took 'laws of nature' literally: René Descartes derived his laws of motion from God's unchanging nature in 1644, and Newton saw the solar system's order as the work of an intelligent Lawgiver.
How the link was found
The idea of a world ordered by divine reason runs from Philo of Alexandria (1st century) and John's Gospel through Kepler, Descartes (Principles of Philosophy, 1644) and Newton's General Scholium (1713).
Is it proven?
A belief, not a testable claim. Many historians hold that it motivated early scientists to look for exact, universal laws; whether it is true lies outside science.
Open questions and mysteries
Does grounding laws in God explain them, or relocate the question? Are laws good because God decrees them, or decreed because they are good?
▸Georges Lemaître kept his Big Bang science separate from "In the beginning was the Word": creation by God's wordFaith & belief
The relationship
Lemaître held that the Bible teaches salvation, not physics, and that his 'primeval atom' neither proved nor denied creation. A beginning in physics, he thought, is not the same as creation in theology. So when Pope Pius XII told the Pontifical Academy of Sciences in November 1951 that modern cosmology bore witness to creation, Lemaître was dismayed.
How the link was found
Lemaître stated his view in a 1933 New York Times interview and at the 1958 Solvay conference. He reportedly worked through Jesuit astronomer Daniel O'Connell to dissuade the Pope; Pius XII's 1952 address to astronomers did not repeat the claim.
Is it proven?
Documented in his own writings and by historians such as Dominique Lambert and Helge Kragh. The Church kept him in high regard: he presided over the Pontifical Academy of Sciences from 1960 until his death in 1966.
Open questions and mysteries
Whether faith and science are fully separate realms, as Lemaître held, or should inform each other is still debated by scientists and theologians alike.
▸The Big Bang was hailed by Pope Pius XII as echoing "In the beginning was the Word": creation by God's wordFaith & belief
The relationship
In an address to the Pontifical Academy of Sciences on 22 November 1951, Pope Pius XII said modern science, by tracing the universe back to a dense beginning, seemed to bear witness to the primordial 'Fiat lux', 'Let there be light' (Genesis 1:3), where God creates by speaking. He presented expansion and age estimates as support for a moment of creation.
How the link was found
Pius XII, in the address known as 'Un'Ora'. Lemaître, a priest and the theory's founder, objected that it blurred science and faith; the pope's later remarks to astronomers, in 1952, were more cautious.
Is it proven?
This is interpretation, not physics. Science cannot test whether the universe was created by God. And the Big Bang theory describes the hot phase, not t = 0 itself, so it does not prove an absolute beginning either.
Open questions and mysteries
Thomas Aquinas held that reason alone cannot prove the world had a beginning; he accepted one on faith, but taught that creation means, above all, that everything depends on God. Whether the Big Bang was a true beginning remains open.
