The scientists who challenged Chrisitian teachings came to bitter ends. Although the vast majority were Christians themselves who had no desire to harm the Church, their findings were completely unacceptable to the popes, saints and theologians who were already committed to a previous version of the truth.
Here is what happened to some of the most famous scientists:
Copernicus had concluded by 1500 A.D. that that the sun is the center of the solar system, but he kept his theories secret for 30 years, not wishing to draw the wrath of the Church. Shortly after publishing Revolutions of the Heavenly Bodies, he died of old age, and was thus spared their angry response. But they got their revenge anyway, by burying him in a grave that marked none of his great accomplishments, but said: "I ask not the grace accorded to Paul; not that given to Peter; give me only the favor which Thou didst show to the thief on the cross." Then they kept silent about his work for 70 years -- until the appearance of Galileo.
Bruno had no such luck; when he publicly defended Copernicus, the Inquisition arrested him, tortured and burned him at the stake.
Galileo, often called "the Father of Modern Science," was the first astronomer to claim actual evidence that the earth was not the center of the universe, but revolved around the sun. For this, Galileo came under intense criticism and persecution from the Church. Pope Urban VIII personally gave the order in 1633 that Galileo, then an old man of 70, should be threatened with torture if he did not renounce the heresy that the earth revolved around the sun. Under repeated threats of torture, Galileo finally renounced his beliefs. He was then placed under house arrest, and not freed even after he went blind. Technically, the Church never convicted Galileo of heresy (only a "vehement suspicion of heresy") but it did make clear that the "heresy" in question was defined as the belief that the earth rotated around the sun. And, to leave absolutely no doubt about how completely it condemned the ideas of Galileo, the Church censored and prohibited all books supporting his scientific findings for over 200 years. This censorship was placed in the Index of Prohibited Books, which was personally signed by every pope who renewed it. Protestants would be mistaken in thinking this is a Catholic embarrassment only. Every Protestant church before 1800 rose in bitter opposition to the "atheistic" findings of Galileo.
Campanella was tortured seven times by the Inquisition for a number of heresies, one of which was writing Defense of Galileo.
Rene Descartes, alarmed by the Inquisition's persecution of Galileo, delayed his plans to publish The World, a book that agreed with Galileo's views. Later he wrote Meditations on First Philosophy, which introduced the idea that truth can be discovered only through scientific investigation and the scientific method. This earned the hostility of the Church, and their persecution caused Descartes much suffering. This great philosopher, who is famous for attempting a logical proof of God's existence, was called an atheist, and his works were placed on the Index of Prohibited Books. Protestant theologians in his resident Holland wanted him tortured and put to death.
Tycho Brahe, Johannes Kepler and Edmond Halley were pioneers in describing the orbits of celestial bodies like comets and planets. The orderly laws of nature they described contradicted the Church's belief that comets were thrown in anger from the right hand of God, or that they portended disaster and war. For over a hundred years the Church argued against them -- to describe how heated, bitter and personal this debate grew in a single paragraph is impossible. But Halley secured the final victory by accurately predicting the return of the comet that now bears his name. All three would have been brought before the Inquisition had they not been Protestant.
Isaac Newton kept his true religious beliefs secret, for fear of persecution, until literally his dying day. He privately rejected his native Anglican Church at about age 30, convinced that its teachings about Christ's divinity and the existence of a Trinity were a fraud. He instead accepted Arianism, a 4th century Christian heresy. Only on his deathbed did he reveal his true beliefs by rejecting the Anglican sacrament. (2) Many Christians opposed his scientific findings as well, for everyone had previously believed that God actively and frequently intervened in the ordinary events of the universe. Christians charged that he "took from God that direct action on his works so constantly ascribed to him in Scripture and transferred it to material mechanism," and that he "substituted gravitation for Providence."
Georges Louis Leclerc Comte de Buffon, one of the more colorful scientists in history, was the first to study fossils and suggest that life forms had changed in the past. The proto-version of evolution earned him the enmity of the Church, which forced him to resign from his Sorbonne University position and recant his views. The Church then humiliated him by publishing his recantation.
William Buckland, Charles Lyell, Louis Agassiz, and Adam Sedgewick were all 19th century Christian geologists who originally set out to prove the story of creation and Noah's Flood. But despite their best attempts to reconcile their discoveries with the Bible, their findings kept pointing in the other direction: namely, the earth was several billion years old, not 6,000. One by one, they recanted their belief in the literal interpretation of Genesis and accepted the findings of modern geology. For their intellectual honesty, they came under terrific attack from the Church, which hurled epithets like "infidel," "impugner of the sacred record," and "assailant of the volume of God." Their geology was condemned as "a dark art," "dangerous and disreputable," "a forbidden province," "infernal artillery" and "an awful evasion of the testimony of revelation."
Robert Chambers created a major scandal in 1844 when he published an anonymous best-selling book entitled The Vestiges of the Natural History of Creation. The book contained the blasphemous suggestion that an orderly progression in the changes of fossils indicated that species themselves had evolved. Religious leaders demanded to learn the identity of the author and denounced the book in the angriest terms possible. The ensuing controversy proved that Chambers had made the correct decision to publish anonymously.
Charles Darwin knew that his revolutionary theories on natural selection would invite the full fury of the Christian world. He therefore delayed publishing his theory for over 20 years, agonizing over the decision of whether or not to publish. His hand was forced in 1858, when he learned that the naturalist Alfred Wallace was about to publish the same theory. His fears proved true -- the reaction from the Church was shock, disappointment and anger. The world-wide attacks on his character, theories and personal life are common knowledge now, but he was saved from physical harm for two reasons. First, nearly the entire scientific community was quick to see the soundness of his theories, and rallied immediately to his defense. Second, the age of the Inquisition and other torture-based persecutions had finally passed.
Bertrand Russell found that Christian persecution exists even in the 20th century. One of the greatest of modern philosophers, Russell angered many Christians with his essay, Why I am not a Christian. And they exacted their revenge in 1940, when Russell accepted an appointment at the College of the City of New York. The Christian community launched a furious and protracted campaign to prevent the appointment, printing slanderous accusations of homosexuality, child molestation, public nudity and lechery. (This, for his mildly liberal views on sex, which would be considered tame by today's standards.) Even New York's highest political officials joined the assault, calling him a "dog" who should be "tarred and feathered and driven out of the country." Christians sued in court to prevent Russell's appointment, and in a trial filled with legal howlers, Russell was barred from teaching in New York State -- in a word, censored.
