The Priest Who Found the Beginning

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

The theory that the universe began — the one the world calls the Big Bang — was proposed by a Catholic priest. Georges Lemaître followed the physics to a beginning, endured the mockery, and was vindicated. Then he did something even rarer: he refused to use his own theory as a weapon to "prove" Genesis, because he believed Scripture and science answer different questions. His life teaches both fearless thinking and careful reverence — and how to hold them together.

Reflection

Two vocations, one man

Georges Lemaître was born in 1894 in Charleroi, Belgium. At seventeen he was studying engineering; at twenty he was in a trench. When Germany invaded Belgium in 1914, Lemaître volunteered, served through the war as an artillery officer, and was decorated for bravery. He had seen the world at its darkest before he ever studied its dawn.

After the war he pursued two callings at once, refusing to choose. He trained for the priesthood and was ordained in 1923; he also threw himself into the new physics, studying under the great astronomer Arthur Eddington at Cambridge, then in the United States, where he earned a doctorate at MIT. He spent his career as a professor at the Catholic University of Louvain — a priest in a clerical collar, filling blackboards with Einstein's field equations. Asked, years later, how he managed both, he answered:

"There were two ways of arriving at the truth. I decided to follow them both. Nothing in my working life, nothing I ever learned in my studies of either science or religion, has ever caused me to change that opinion." — Georges Lemaître, interview, 1933

Two paths, one truth — because one God stands behind both. Notice the quiet confidence in that sentence: a lifetime of equations and a lifetime of sacraments, and not one collision worth reporting. That conviction was about to be tested in the most public way imaginable.

The day the universe got a birthday

In the 1920s nearly every physicist, including Einstein, assumed the universe was eternal and static — it had always been here, doing roughly this. In 1927, working through Einstein's own equations, the young Belgian priest found they said otherwise: the universe should be expanding, space itself stretching, galaxies riding apart like raisins in rising dough. He even derived the law relating a galaxy's distance to its speed — two years before Edwin Hubble published the observations. In 2018 the world's astronomers voted to rename it the Hubble–Lemaître law, giving the priest his overdue credit.

Einstein's first reaction was withering. Your mathematics is correct, he told Lemaître, "but your physics is abominable." Lemaître pressed on. In 1931 he took the final step: run the expansion backward, and everything converges. The universe, he proposed, began from what he called a "primeval atom" — all matter, energy, space, and time compressed into one initial point, a "day without a yesterday." Colleagues were appalled; an eternal universe felt scientific, while a universe with a beginning sounded suspiciously like religion. Years later the astronomer Fred Hoyle, who never accepted the theory, derided the idea on the radio as a "big bang." The mockery became the name. The name became the textbook. Decades of evidence — above all the cosmic microwave background, the leftover glow of the early universe, detected in 1964 — settled the matter. Lemaître, dying in 1966, lived just long enough to hear that the glow had been found. Even Einstein had long since come around; after a 1933 lecture, he reportedly led the applause for what he called one of the most beautiful explanations of creation he had ever heard.

A priest had discovered that the universe has a birthday. And the Bible's first sentence had been there all along: Genesis 1:1-3 — "In the beginning, God created the heavens and the earth... And God said, 'Let there be light,' and there was light." So did the New Testament's verdict on origins: 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." Not made out of visible stuff — a sentence that sounds different after Lemaître.

Long before any of this, Augustine had pondered what "in the beginning" must mean and reached a conclusion that still startles physicists:

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

Time itself is a creature. There was no endless clock ticking before creation, with God waiting around in it. That is fifth-century theology — and it is also, roughly, what Lemaître's physics implied. The priest knew his Augustine.

The pope, the physicist, and the honest "no"

Now comes the moment that makes Lemaître a model and not just a milestone. In 1951, Pope Pius XII declared in a public address that the new cosmology seemed to confirm the doctrine of creation — that the Big Bang looked like scientific witness to "Let there be light." You might expect the priest who fathered the theory to be thrilled. He was horrified.

Lemaître — by then a member, later president, of the Pontifical Academy of Sciences — quietly intervened, and the pope did not press the argument again. Why would Lemaître refuse the greatest endorsement imaginable? Because he loved both books too much to see either misused. He had explained his position years earlier:

"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

His logic was simple and pastoral. Scientific theories are revisable; if you chain the faith to today's model, you crucify the faith on tomorrow's revision. Imagine a preacher in 1920 declaring that the eternal, static universe proved God unnecessary — and then 1927 arrives. Lemaître refused to make the same blunder in reverse. If his primeval atom was ever overturned, he wanted no Christian's faith buried in the rubble; and if it stood, he wanted no skeptic able to sneer that the priest had cooked the physics to flatter his catechism. And Scripture's purpose was never to scoop the physics journals. Paul tells Timothy exactly what the holy writings are for: 2 Timothy 3:15 — "the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus." Wise for salvation — that is the Bible's job description, in its own words. Genesis 1 tells you, unfailingly, who made everything, why it is good, and what it all means. The equations tell you how the expansion ran. Confuse the two assignments and you damage both. John Calvin used an unforgettable image for what Scripture actually does:

"Just as old or bleary-eyed men... with the aid of spectacles will begin to read distinctly; so Scripture, gathering up the otherwise confused knowledge of God in our minds, having dispersed our dullness, clearly shows us the true God." — John Calvin, Institutes of the Christian Religion

Scripture is the spectacles, not the telescope. Put it on, and then look at the universe — including a universe 13.8 billion years deep — and you finally see whose it is. Francis Schaeffer compressed the whole foundation into seven words:

"He is there, and he is not silent." — Francis Schaeffer, He Is There and He Is Not Silent

The One who remains

Stand where Lemaître stood and let the scale hit you. Every galaxy, racing outward. Every star, burning down. The whole cosmos, dated. Pascal — our friend from Day 3 — felt the vertigo of being a thinking speck in all that immensity:

"For in fact what is man in nature? A Nothing in comparison with the Infinite, an All in comparison with the Nothing, a mean between nothing and everything." — Blaise Pascal, Pensées

The Bible feels the same vertigo — and then plants its feet: 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." The universe has a birthday. God does not. And there is wisdom's voice in Proverbs, present at the founding like a master craftsman at God's side: Proverbs 8:27, 30-31 — "When he established the heavens, I was there... then I was beside him, like a master workman, and I was daily his delight, rejoicing before him always, rejoicing in his inhabited world and delighting in the children of man." Creation began in delight — and the delight included us.

Here is the gospel turn, and it is breathtaking. Psalm 102:25-27 says of God: "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." Then the New Testament does something audacious: Hebrews 1:10-12 takes that entire passage and addresses it to Jesus. "You, Lord, laid the foundation of the earth in the beginning... they will perish, but you remain." The everlasting One who lit the primeval fireball is the same Lord who was born in a stable, died on a cross, and rose — the Beginning, it turns out, has a face and a name. Lemaître the physicist found the universe's first day. Lemaître the priest already knew its first Word. He spent his life refusing to confuse the two discoveries — and worshiping the One behind both.

Going Deeper

Practice Lemaître's honesty this week in one conversation. If science and faith come up — at school, at work, online — resist both lazy moves: don't say "science has disproved God" and don't say "science has proved him." Instead, try his distinction out loud: the Bible tells us who and why; science explores how and when; one God is Lord of both. Then read Genesis 1:1 tonight, slowly, wearing it as spectacles rather than wielding it as a textbook — and end the way Lemaître's own story ends, with worship.
