The Catholic Church disagrees: In Catholic theology, papal infallibility is the dogma that, by action of the Holy Spirit, the Pope is preserved from even the possibility of error[1] when he solemnly declares or promulgates to the Church a dogmatic teaching on faith or morals as being contained in divine revelation, or at least being intimately connected to divine revelation.
No Pope has ever altered any doctrine the Church teaches. This is an impossibility - the Pope has no authority to change any teaching.
So Galileo really as wrong and the sun revolves around the Earth?
No Pope has ever married.
Never heard of St. Peter?
Pope Sergius III (904–911) was supposedly the father of Pope John XI by Marozia (Source: Liber Pontificalis, Liutprand of Cremona).
Pope John XII (955–963) (deposed by Conclave) was said to have turned the Basilica di San Giovanni in Laterano into a brothel and was accused of adultery, fornication, and incest (Source: Patrologia Latina).
Pope Benedict IX (1032–1044, again in 1045 and finally 1047–1048) was said to have conducted a very dissolute life during his papacy.
Pope Alexander VI (1492–1503) had a notably long affair with Vannozza dei Cattanei before his papacy, by whom he had his famous illegitimate children Cesare and Lucrezia. A later mistress, Giulia Farnese, was the sister of Alessandro Farnese, who later became Pope Paul III. He fathered a total of at least seven, and possibly as many as ten illegitimate children.[14] (Also see Banquet of Chestnuts.)
As far as the Catholic church condoning prostitution, I suggest you familiarize yourself with St. Thomas Aquinas words on the subject.

Then you proceeded to prove that I was right and that you were wrong by posting:
papal infallibility is the dogma that, by action of the Holy Spirit, the Pope is preserved from even the possibility of error when he solemnly declares or promulgates to the Church a dogmatic teaching on faith or morals
How can someone be intrinsically infallible when his gift of infallibility only obtains under certain very specifically limited guidelines?
Think it through before you answer.
Never heard of St. Peter?
No one on your list ever took a wife after he was elevated to the Papacy. And your list contains a number of historical inaccuracies. John XI's father was Duke Alberic I of Spoleto, for example.
As far as the Catholic church condoning prostitution, I suggest you familiarize yourself with St. Thomas Aquinas words on the subject.
Thomas Aquinas never wrote a single word condoning prostitution. If you are going to make such a ridiculous claim, perhaps you should provide some kind of cite for it.
The astronomer Copernicus taught that the earth revolves around the sun. His book on the topic was published at Rome with papal imprimatur.
His friend and colleague Johannn Widmanstetter lived in Rome and delivered a lecture on heliocentrism to Pope Clement VII and his court and was thanked by the Pope. The Pope's right hand man, Nicholas Cardinal Schoenberg, sent Copernicus a letter complimenting him on his research and asking for more information - a letter which Copernicus proudly had printed in subsequent editions of his book.
The lectures took place in 1533.
Galileo published his book in 1616.
Leaving aside the fact that the Church has never taught geocentrism as a dogma (I challenge you to cite any authorized catechism, papal bull, papal decree, papal decretal, papal rescript, papal encyclical or any decree of any ecclesiatical council which makes such a claim), it is clear that Copernicus taught heliocentrism - 30 years before Galileo was born - without controversy.
Galileo's condemnation was not about science, but about court politics.
