A Universe with a Birthday

Today's Scripture

Genesis 1:1-3 — "In the beginning, God created the heavens and the earth. The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. And God said, 'Let there be light,' and there was light."

Psalm 90:2 — "Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God."

Hebrews 11:3 — "By faith we understand that the universe was created by the word of God, so that what is seen was not made out of things that are visible."

The Big Idea

For most of history, scientists and philosophers assumed the universe was eternal — it had simply always been there. The Bible stood almost alone in insisting on a real beginning. Then, in the twentieth century, a Belgian priest who was also a brilliant physicist read the equations and announced that the universe had a birthday. The resonance with "In the beginning" is real and worth feeling — as long as we hold it the way he did: with open hands, not clenched fists.

Reflection

The eternal universe everyone assumed

It is hard for us to feel how strange the Bible's first sentence once sounded. Genesis 1:1 — "In the beginning, God created the heavens and the earth." A beginning? Aristotle taught that the cosmos was eternal, with no start at all. Most ancient cultures agreed: matter is just there, endlessly recycled. And the assumption lasted. Into the early twentieth century, the consensus picture was a static, everlasting universe. When Einstein's own equations of general relativity hinted that the universe could not be sitting still, he famously added a term to hold it steady — he later regarded that move as a great blunder.

Against all that, the church had been making an audacious claim for centuries: not just that the universe began, but that time itself began. Augustine worked this out around AD 400, with no telescope, just Genesis and hard thinking:

"The world was made, not in time, but simultaneously with time." — Augustine, The City of God

Sit with that. Augustine saw that asking "what happened before creation?" is like asking what is north of the North Pole. There is no before, because "before" is a time word, and time is itself a creature — part of the made world, as much a thing God invented as light or water. Sixteen centuries later, that is essentially how modern cosmology describes the beginning: not an explosion in space and time, but the beginning of space and time. Augustine knew the question was hard. He admitted as much, in one of the most honest sentences ever written:

"What, then, is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know." — Augustine, Confessions

The Bible, meanwhile, simply talks this way without strain. Psalm 90:2 — "Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God." 2 Timothy 1:9 says God gave us grace in Christ Jesus "before the ages began" — a phrase that quietly assumes the ages began. And Proverbs 8:27-30 pictures God's wisdom present at the founding: "When he established the heavens, I was there... then I was beside him, like a master workman, and I was daily his delight." Creation, in Scripture, is not an accident or a recycling. It is a project with a first day — and joy on site.

The priest who did the math

Now the part of the story almost nobody learns in school. The man who first proposed what we now call the Big Bang was a Catholic priest.

Georges Lemaître was ordained in Belgium in 1923, having already survived the trenches of World War I. He was also a physicist of the first rank — Cambridge, Harvard, MIT. In 1927 he published the calculation that the universe is expanding, with galaxies racing apart like raisins in rising dough. Run the film backward, he reasoned, and everything converges: all matter, energy, space — and time itself — traced back to what he called a "primeval atom," the beginning he liked to describe as "a day without a yesterday."

The reception was chilly. Einstein, meeting him at a conference that year, reportedly told him his mathematics was correct but his physics was abominable — the idea smelled too much like Genesis. The great astronomer Fred Hoyle, who championed an eternal "steady state" universe, coined the name "Big Bang" on BBC radio as a sneer. The sneer stuck as the name; the theory stuck for better reasons. Edwin Hubble's observations confirmed the expansion. Then, in 1965, two radio engineers in New Jersey found a faint microwave hum coming from every direction in the sky — the leftover warmth of the beginning itself, exactly the kind of afterglow the theory predicted. Lemaître was an old man in a Belgian hospital by then, and friends brought him the news shortly before he died: the beginning he had calculated four decades earlier had left a glow, and the radio telescopes had found it. The universe, it turns out, has a birthday. Hardly anyone in science had expected one. The first page of the Bible had said so all along.

The man who refused to overclaim

Here is where the story turns from satisfying to genuinely instructive. Because the priest who found the beginning spent real energy refusing to weaponize it.

In 1951, Pope Pius XII gave an address suggesting that Big Bang cosmology confirmed the doctrine of creation — science had all but proven Genesis. You might expect Lemaître to be thrilled. He was alarmed. He quietly counseled the Vatican against making that argument, and the pope did not press the claim again. Lemaître insisted his theory described the physical beginning of our universe, not the metaphysical act of creation — those are different questions, and confusing them hurts both faith and science:

"As far as I can see, such a theory remains entirely outside any metaphysical or religious question." — Georges Lemaître, "The Primeval Atom Hypothesis," 1958

Why so careful? Two reasons, both wise. First, scientific theories get revised; if your faith is bolted to today's cosmology, it wobbles with every new paper. A church that had said "the Big Bang proves Genesis" in 1951 would have been hostage to every conference since. Second, and deeper: Lemaître understood what kind of book the Bible is.

"Once you realize that the Bible does not purport to be a textbook of science, the old controversy between religion and science vanishes." — Georges Lemaître, interview, 1933

He liked to say there were two ways to truth, and he had chosen both. He read the equations as equations and the Scriptures as Scripture — two books, neither forced to do the other's job. That is exactly the posture Hebrews 11:3 describes: "By faith we understand that the universe was created by the word of God." Notice: by faith, not by telescope. The microwave background can show you a hot, dense beginning. It cannot show you the Voice that said, Genesis 1:3 — "'Let there be light,' and there was light." That, only the second book tells you — and trusting it is not a lab result but a relationship.

Other believing scientists weigh the resonance a little differently. Francis Collins, looking at the same physics, finds it personally compelling:

"The Big Bang cries out for a divine explanation... I cannot see how nature could have created itself. Only a supernatural force that is outside of space and time could have done that." — Francis Collins, "Why This Scientist Believes in God"

Notice his words: cries out for. Not "proves." A pointer, not a padlock. Collins and Lemaître would agree on this: the beginning is a place where the two books hum at the same pitch — and humming is not the same as a signed confession. Held humbly, the resonance is allowed to do what resonance does: make you lean in and listen.

The God who has no birthday

So what does a universe with a birthday actually preach? Not "gotcha." Something better: everything you can see is a creature.

Psalm 102:25-27 — "Of old you laid the foundation of the earth, and the heavens are the work of your hands. They will perish, but you will remain; they will all wear out like a garment... but you are the same, and your years have no end." Even the stars are wearing out like a favorite sweater. Cosmology agrees: stars burn down, the universe runs down. Only One has no birthday and no expiration. And he is not an absent landlord — Isaiah 40:26 — "Lift up your eyes on high and see: who created these? He who brings out their host by number, calling them all by name; by the greatness of his might... not one is missing." The God who started time does roll call for stars. Every night. By name.

C.S. Lewis draws the line that keeps all of this from becoming abstract:

"What God begets is God; just as what man begets is man. What God creates is not God; just as what man makes is not man." — C.S. Lewis, Mere Christianity

Everything in the universe is made — galaxies, time, you. But the Son, the gospel says, is begotten, eternally of the same nature as the Father, present at the beginning the way Proverbs 8 pictures wisdom: beside him, like a master workman, daily his delight. And here is the staggering part: that eternal Son entered his own dated, expiring universe. The One through whom time began submitted to clocks — nine months in a womb, thirty-three years under Roman occupation, three days in a tomb. He did it so that creatures of dust and deadlines could share his kind of life, the kind Psalm 90:2 sings about: from everlasting to everlasting.

The universe has a birthday. Because of Jesus, so does your eternal life — and unlike the stars, it has no expiration date.

Going Deeper

Tonight, step outside and find one star. The light hitting your eye left that star years — maybe centuries — ago; you are looking at the past, inside a universe that has an age. Say Isaiah 40:26 over it: "Lift up your eyes on high and see: who created these?" Then thank the God who has no birthday that he calls that star — and you — by name.
