Was any Doctor of the Church martyred?

**Are there any Early Church Fathers or Doctors of the Church or Catholic Saints who believed the world would possibly end by a comet hitting the earth or coming in close contact with it?** The other day, I heard about NASA’s attempt to deflect a comet that might be on a collision course with the bright blue planet we live on. If this comet hits us, it could possibly alter the way we live on earth. I doubt the asteroid will hit the earth, but my unwelcoming question stands. > NASA predicts that the massive asteroid will pass by Earth on December 11, just a month and a few days from now. The asteroid has been classified as 4660 Nereus, and NASA does consider it very hazardous. The organization says that the asteroid is almost three times the size of a football pitch — roughly the size of the Eiffel tower. > > While it could be hazardous if it hits the Earth, NASA says the asteroid will fly by the planet at a distance of roughly 3.9 million kilometers. That distance is ten times greater than the area between the Earth and the moon, so it shouldn’t cause any issues on our planet. In the past, scientists have considered missions to the asteroid, but have never gone through with them. > > Eleanor F. Helin originally discovered 4660 Nereus in 1982. Nereus is just one of several asteroids included in the Apollo group. All of the asteroids in this group are known for passing close to the Earth as it orbits the sun. > > The asteroid orbits the sun every 664 days. However, scientists predict that it won’t come close to the Earth again until March of 2031. After that, it’s expected to come close again in 2050, though its closest approach isn’t predicted to arrive until February of 2060, roughly forty years down the line. As is the case with next month’s pass, however, neither of those passes are expected to be close enough to pose any risk of impact. - NASA is tracking a 1,000-foot-tall asteroid that’s headed towards Earth In case no Early Church Father or Doctor of the Church can be found to hold this possibility, are there any historical canonized saints of the Catholic Church who have predicted such a possibility?

If one checks the *Wikipedia* entry on [Cyril of Alexandria](https://en.wikipedia.org/wiki/Cyril_of_Alexandria) , there is no indication that he is venerated as a Saint in the Roman Catholic Church. But, although it is not indicated there, I am under the impression that (somehow) he is venerated as a Saint in the Byzantine Catholic Church, one of the 23 Eastern rites in full communion with Rome. But, of course, (Saint) Cyril of Alexandria has been declared one of the thirty-six doctors of the Roman Catholic Church. See, for instance, the [chronological list of the doctors of the church](https://uscatholic.org/articles/200807/chronological-list-of-the-doctors-of-the-church/) . QUESTION: Has (Saint) Cyril of Alexandria ever been canonized (or officially recognized as a Saint) by the *Roman Catholic Church?* If not, how is it possible that he was proclaimed a Doctor of the Church by Pope Leo XIII in 1882?

**According to Catholicism, did the Apostles enjoy the prerogative of infallibility?** The doctrine of papal infallibility was defined by Pope Pius IX in 1870! Does the Catholic Church recognize that the 12 Apostles of Our Lord enjoyed this privilege also? Are there any other Divine Privileges that the Apostles may have enjoyed, whether defined in principle or simply believed by certain Catholic theologians, Doctors of the Church or Church Fathers?

**According to Catholicism, why did Jesus tell His disciples to buy a sword?** > > 36 But they said: Nothing. Then said he unto them: But now he that hath a purse, let him take it, and likewise a scrip; and he that hath not, let him sell his coat, and buy a sword. > > 37 For I say to you, that is written must yet be fulfilled in me: And with the wicked was he reckoned. For the things concerning me have an end. > > 38 But they said: Lord, behold here are two swords. And he said to them, It is enough.- [Luke 22:36-38](https://www.biblegateway.com/passage/?search=Luke%2022&version=DRA) Have any Church Father or Doctor of the Church offer any insights as to why Our Lord spoke as such? I am rather curious also if the word for ***sword***, could have been the same word used for a dagger? For in such a case, a dagger could in theory also be used as a fork when eating as well as for self defense! In the movie, **The Passion of the Christ**, Peter cuts off the ear of [Malchus](https://en.wikipedia.org/wiki/Malchus#:~:text=According%20to%20the%20Bible%2C%20one,prevent%20the%20arrest%20of%20Jesus.) with what looks more like a dagger in lieu of an actual sword. The Hebrew word **חֶרֶב**: Axe, dagger, knife, mattock, sword, tool for cutting [Strong's Concordance](https://www.quotescosmos.com/bible/bible-concordance/H2719.html#verses)

Is there a Church Father or Doctor of the Church who wrote that Judas Iscariot was saved and indicated why he believed this was so? I actually think one actually put forth their reasons for this, but memory fails me as to who it was. Perhaps it may have been a well-known theologian. I would like to read his reasoning on this issue. Archbishop Paglia says it is heresy to say Judas is in hell! Possibly he was inspired by a Doctor of the Church or Church Father? > Faithful Catholics are criticizing his comment, recalling how Our Lord spoke of Judas: "The Son of Man indeed goes, as it is written of him: but woe to that man by whom the Son of Man shall be betrayed. It were better for him, if that man had not been born." > > The Saints, Fathers and Doctors of the Church say unanimously that Judas is in Hell. - Archbishop Vincenzo Paglia contradicts the tradition of the Church

This is a question directed at Roman Catholics, or anyone familiar with the history of the Roman Catholic church. Every Doctor of the Church is a saint. I was curious if this is perhaps a requirement to be recognized as a Doctor, or if it is merely a "coincidence" (i.e. unintentional by the church) that all Doctors also happen be saints? I've also noticed that some Doctors of the Church are also Early Church Fathers. The opposite is not true though - not all Fathers of the church are necessarily Doctors (see Origen, for example). What exactly are the requirements to be appointed a Doctor of the Church?
