Galileo and Why He was Really Convicted of Heresy

By | August 29, 2019

On October 31, 1992, the Roman Catholic Church
admitted it had been wrong to condemn Galileo Galilei for promoting the Copernican astronomical
theory. After a 13 year investigation into the persecution
of Galileo that led to his official condemnation in 1633, Pope John Paul II rectified a wrong
that forced the Italian astronomer and physicist to live the last years of his life in exile,
and worse yet, to recant his proven discoveries to save his hide. Through his use of the telescope – a tool
he did not invent but greatly improved upon -Galileo proved the Copernican theory that
Sun, and not the Earth, was the center of the solar system. This scientific fact was in direct contradiction
to certain interpretations of scripture and was therefore considered heresy at the time. The relevant text included Psalm 104:5, “the
Lord set the Earth on its foundations; it can never be moved…” But Galileo had influential patrons such as
the Medicis and Barberinis, and Pope Urban VIII happened to be a member of the Barberini
family, as well as a close friend and great admirer of Galileo’s. Pope Urban VIII also, before being raised
to Pope, opposed a previous attempt at condemning Galileo in 1616. In the end, the Pope allowed Galileo to continue
his study into both the Ptolemaic and the Copernican theories, on the condition that
he drew no definitive conclusion that would contradict Church teachings. Instead, he was to merely present the cases
for and against both sides of the argument, staying neutral in the telling. Galileo agreed, but when he published “Dialogue
Concerning the Two Chief World Systems,” it was a ringing endorsement of Copernican
thought in direct defiance of the Pope’s order. However, Galileo, who was Catholic himself,
took the position that this was not in opposition to scripture because not every passage should
be taken literally, particularly ones dealing with lyrics to songs, a position shared by
many even among the clergy. He might have gotten away with this even still,
except for one little fact not often talked about. The Pope had requested that Galileo include
the Pope’s own thoughts on the matter. Galileo did this, but in such a way as to
make the Pope look the fool, incorporating his ideas into the arguments of “Simplicio,”
(with connotations of “simpleton” in the name) who defended the Geocentric view, often
with bumbling errors in the process. It’s not thought that Galileo intended to
make fun of the Pope in doing this. He was no fool himself and even explicitly
stated in the preface that “Simplicio” was in homage to the philosopher Simplicius. Nevertheless, Pope Urban VIII certainly felt
like he was being mocked in seeing some of his own words put into the mouth of Simplicio. Needless to say, making the Pope feel like
you were publicly calling him an idiot was not a good idea when you’re writing already
highly controversial scientific notions about the universe that is likely to antagonize
the Catholic church. Because of his perceived heresy, Galileo was
summoned to Rome to appear before the dreaded Inquisition. During his trial, Galileo fervently denied
that he had advocated for the Copernican view in his work, despite all evidence to the contrary. Despite threats of torture, he still held
onto his denial. Nevertheless, he was convicted of “suspected
heresy” and was required to “curse and detest” the Copernican viewpoint. Galileo was placed under house arrest in his
home near Florence until his death in 1642 at the age of 77 (though was permitted to
travel to Florence to see doctors). Beyond being under house arrest, his punishment
was relatively light compared to others who’d been convicted of heresy. He was, for a time, required to recite seven
psalms of penitence once per week, but Maria Celeste, his daughter, was eventually able
to convince the church to allow her to fulfill this punishment for him. With nothing better to do while confined to
his home, he wrote perhaps his most famous work, Two New Sciences, which more or less
summarized his life’s work. After several failures to get this new work
published, due to the prohibition on any of his writings, he finally found a publisher
in Holland willing to risk the Catholic church’s ire in publishing it. Since then, the Catholic Church has taken
several steps to reverse its stance against Galileo’s findings prior to the action in
1992. Galileo’s “Dialogue Concerning the Two
Chief World Systems” was stricken from the Index, a list of banned publications, in 1757. A preliminary report conducted in 1984 by
scientists, theologians, and historians surmised that Galileo had been falsely condemned. Pope John Paul II concluded that he had been
“imprudently opposed.” The leader of the investigation conducted
in 1992, Cardinal Paul Poupard, said, “We today know that Galileo was right in adopting
the Copernican astronomical theory,” a statement that would have put him at risk of being arrested,
and possibly executed, by his own Church just a few hundred years previously.

    FYI(and it's a non-Catholic that knows this) the Black Pope(a name, he was Italian) was the Father-General of the Society of Jesus(Jesuits), and the bother of the pope.

    So you're saying, even Galileo, smart as he was … "didn't expect the Inquisition"?

  3. Max Wylde Post author

    For perhaps the first time, you got some things wrong here, and you're presenting things in a rather unfair tone. The problem is that there's so much that you failed to put in. For one, Galileo could not prove his theories at all, and anyone calling themselves a scientist who cannot prove his theories and then demands that everyone accept them is not a scientist, but a huckster. What's more, he was a complete jerk; if you disagreed with anything he postulated, even if you could prove he was wrong (Johannes Kepler), he'd call you every name in the book, ridicule and degrade you.

    The problem was that he did openly ridicule the Pope, a man who was his friend, all for what? A theory that he could not prove, and was actually wrong about!

    What was he wrong about? That A) the Sun is the center of the universe, and B) that the orbits of the planets were Circles, not Ellipses, which Kepler pointed out mathematically (but, Kepler at the time said even he could not prove this because he didn't have adequate technology to verify it – this would happen sometime in the 19th Century). Also, Galileo denounced the idea that the moon was responsible for the tides. Not very scientifically minded, wouldn't you say?

    Open defiance of Papal authority, which Galileo had done, is heresy; that's what he was convicted of. Not of promoting heliocentrism, which some Inquisitors did say was " All have said the stated proposition (heliocentrism) to be foolish and absurd in philosophy; and formally heretical…"

    However, it was the Pope himself who had Galileo publish his ideas. Why, if heliocentrism is heresy, would the Pontiff, the Vicar of Christ Himself, lead someone to commit a mortal sin? (Not just Galileo, but Copernicus too – the Pope had him publish his ideas, but unlike Galileo, Copernicus had the honesty to admit he couldn't prove anything. By the way, look up a guy named Cardinal Nicolas of Cusa – he postulated a heliocentric theory before Copernicus – and he's a Cardinal, which means a special kind of Bishop.)

    Because, you see, folks, priests can error; the Pope never gave such a teaching ex cathedra. There really is nothing contradictory about heliocentrism in Holy Scripture. The Church, the only Church Jesus Christ, Himself, founded, is filled with human beings, and they make mistakes.

    And at a time of the Protestant Revolt, where the Church was being torn apart by fell forces looking to loot for their own gain, having someone like Galileo openly defy the Pope the way he did was a very bad move.

  8. Kurt Arbuckle Post author

    I love your channel, but you may have gotten this one wrong.

    G had an air tight case against heresy on Copernicanism. He had permission to do the book in writing from the Pope and stuck to the terms. Even if the Pope were embarrassed, there was nothing he could have done. In fact, quite to the contrary, the Pope’s affection for G probably saved his bacon.

    The Church did not really care that much about the sun. But it did care about the Eucharist. Turns out G was also an atomist and the Church considered that directly opposing the transmutation of wine and bread to the blood and body of Christ.

    Research indicates that the Pope was very concerned and talked to others about the problem. The Copernicus plea was a plea deal to the lesser charge. The agreement with the Pope on the book was never offered into evidence and the deal was struck the night before it was to have been offered. Had it been offered, the response would have been heresy for atomism, and that would have been the death sentence. It is inconceivable that the Pope did not approve this and probably pushed for it.

    Like any history video, there is a lot of details that are often missed. I read a book on this a while back, and I recall that he had a decree from the pope to publish his works. It was only when a new pope arrived that the decree was not accepted by the church and problems arose with the church. Plus there was other factors as other commenters have pointed out.

    the church tried to keep the knowledge of the ancient alive when most of Europe was in a constant state of war and anarchy following the fall of Rome. When Chaarlmage United much of Europe their was a resurgence of advancement because Europe for the first time was politically stable in 4 centuries. When his Empire fell that stagnated as the chaos returned and much of Europe for the rest of the middle ages was on a slow rebuilding as newly 7 centuries of war and conflict do not equal time for advancement. You need a stable society for that and Europe didn't truly stabilize until the 14 century… before getting hit by the black death. It's only by the Renaissance could Europe be back on track because the large term chaos had finally subsidized.

    You tend to forget a massive political power simply falling into anarchy does not equal to advancement and keep in mind it isn't till 1/3 of Europe is killed that a need to better teach the lowers class (who before the fall of Rome tended to be illiterate and stayed that way long until the early modern day) how to read.

    Also the papacy was only used by the rulers to get what they wanted. France straight up Stole the Papacy crowned there own pope and moved it to a French city in late 1200s. What they did should have been impossible it was outright hersey but they did and got away with it because the churches power was really paper thin.

    Europe in the middle ages wasn't ruled by a oppressive religious institution. It was a chaotic mess, a power vacuum that kept descending into anarchy when it tried to pull itself out. Your be surprised how many kingdom's where born and destroyed in the span of a century or so if you looked up history, how unstable the kingdoms where and how weak the church really was in the realms outside of Rome.

    Galileo argued the planets revolve around points of empty space, and that those points of empty space revolve around the sun. This was the only way he could explain the retrograde motion of planets. Not too bright.

    Kepler discovered orbits are actually elliptical, thus proving Copernicus.

    When there's a conflict between the Church's Doctrine and the Scriptures or the Truth, the Church Leadership will always rule on the side of the Church Doctrine set by earlier Church Leaders no matter how wrong the Doctrine is. This is because to say earlier leaders made mistakes is to imply they can make mistakes as well. A reversal only comes about after a gigantic amount of pressure is placed on the Church Leaders and they see no other option available to them without losing all of the power they have.

  23. Parbruek Post author

    This video omits the actual reason Galileo was convicted, like almost every other account. Galileo deserved the conviction, because he couldn't prove that the earth moved. I.E. he was arguing for a specific interpretation of scripture from science before the science existed. It was actually Kepler's work that finished Galileo's argument. Galileo thought that the solar tide was a reflection of the lunar tide occuring within the Mediterranean. As a result, his argument that the earth was mobile as seen from the tides was rather foolish.

    Screw the Church for persecuting Galileo. You'd think God's spokesman — which is what the Pope is supposed to be — could take a little ribbing. I wouldn't conceptualize his woes as his fault. Not that that's what you're doing here, but it could be taken taken that way.

    0:47 The scripture mentioned says "The earth is set in its foundations; it cannot be moved." I suppose people then had no idea what it meant.

    So, in the end, he was still convicted, and the church still couldn't bear to hear a word said against it. Yet one more reason to hate religion.

  30. DuelScreen Post author

    CORRECTION: There is no biblical scripture that stated the Earth was the center of the universe. The ancient writers had no concept of a modern solar system so this belief that the Earth must be the center was an interpretation. Interpretations, being human endeavours, are often wrong but this in no way applies to scripture.

    Please be more careful in your language in the future. Also, maybe read the scriptures to see what they contain for yourself.

Kudos to "Today I Found Out" for clearing up the historical aspects of the non-scientific aspects of the conflict between Galileo and the Pope.

    I have read the bible many times and nowhere does it describe the orbit of the celestial bodies other than to state that the Sun rises and sets in a "circuit". But it was not trying to literally describe the relative movements of the Earth and Sun. For all practical purposes the Sun appears to be moving while the Earth appears to be stationary. The authors of the bible didn't give two shits about science. It was the pagan Romans and Greeks who gave us mathematics and natural philosophy.

    That's false, Galileo proved no such thing. He thought that he proved it because he didn't have enough knowledge. Anyone who goes into space without a fisheye lens can see that it is flat and if you can stand in one spot hovering in space in a balloon, you can see the sun getting closer and bigger. If the sun was the center, it wouldn't change size with altitude.

    This video is so dead wrong in so many supposed facts about the Galileo affair. Galileo was dead wrong is still dead wrong today! The Church though, taken aback by later supposed scientific discoveries affirming Galileo's findings….never ever "un-condemned" Galileo!

    As a matter of fact…EVERY single argument Galileo used for his defense ….we now know today are blatantly false!!

    The Church formally condemned Galileo and his findings asserting that the Earth in fact does not move and any notion that it does with regard to it's position in the universe is a formal heresy. Any notion as well that the Sun is the center of the universe and does not move is also formally condemned and is still dogma today!!

    This video is totally BS and without any merit whatsoever! 👎🏼
