Although he didn’t ascend to the papacy until he was over eighty years old, Pope Gregory IX was the pope for 14 years -- and managed to do a lot of damage in that time. From picking on the Jews to taking a bizarre stance on cats that ultimately made the Black Death much worse, Gregory IX’s papacy offers several reasons why he was one seriously dangerous pope. Oddly enough, one of the more positive acts of Gregory IX was to establish a Papal Inquisition -- but more on that in a moment.
Pope Gregory IX and the Jews
In 1234, Pope Gregory issued Decretals -- which are papal decrees meant to address a point of canon law -- that were meant to reinforce his power over the Church. One such point of law was the doctrine of perpetua servitus iudaeorum, meaning “perpetual servitude of the Jews.” He invested this doctrine with the force of canon law, and it meant that the Jews would be in a position of political servitude until Judgment Day.
What this meant in practical terms was that the Jews couldn’t have any direct part in the political process. Also, because of the mistaken belief that Jews worshiped the Talmud, Gregory ordered that all copies of the Talmud be confiscated. As a result of this and of Christian-Jewish disputations, on June 12, 1242, 12,000 handwritten copies of the Talmud were burned in Paris.
Okay, we get it: Gregory IX was not a cat person. But he took his dislike of felines to the next level when he issued a papal bull, the Vox in Rama, that condemned devil worship...and, oh yeah, black cats.
The document specifically targeted black cats, which were alleged to be an incarnation of Satan. As a result, black cats were regularly killed up until the 19th century.
Because this cat-culling had a deleterious effect on the overall population of cats, it was easier for rats to proliferate in Europe in the decades that followed. Some historians posit that since the rat population was larger than it would have been had the cats been left alone, and because the bubonic plague is carried by rats, Gregory IX inadvertently caused the Black Plague that hit Europe a century after his death to be much worse than it otherwise would have been.
The Papal Inquisition of the 1230s
No, it’s not this Inquisition:
The Spanish Inquisition of the late 1400s was a different sort of affair from Gregory IX’s Inquisition. In fact, Gregory’s aim in instituting the Papal Inquisition was to keep local civil authorities and hordes of angry villagers in France and Germany from torching individuals suspected of heresy.
Because heresy was a crime against the state, not the Church, it could just as easily be used to conveniently get rid of one's political enemies as to target actual heretics. Gregory’s Inquisition actually saved thousands of people who, justly or unjustly, were accused of heresy or sorcery.
Pope Gregory IX also encouraged Crusades and squabbled with the Holy Roman Emperor, Frederick II, for not making the Sixth Crusade happen in a more timely manner. So in Gregory IX, we have a Jew-hating, cat-hating, book-burning pope whose most laudatory act was an Inquisition. That’s why he gets our vote for one of the most controversial popes in history.
