You are claiming that the Church teaches something stupid.  It makes the Church look stupid and it makes you look stupid. Then when we want to talk about important things pertaining to salvation, people aren't listening because they have already decided we are stupid.
Flat earth is exactly the sort of stupid thing that St. Augustine was writing about.

Yes, in the early period of the Church some of the Church Fathers believed in a flat earth.  The position of Catholics had changed by the time of Isidore of Seville. (around 600 AD).  From that time on Christian thinkers all accepted the earth is a globe: Venerable Bede, Albert the Great, Thomas Aquinas, Roger Bacon.  This is what was taught at Catholic universities starting in the middle ages (historically these were religious institutions.)  This idea was not introduced by the Reformation as you claimed earlier.  It was the natural development of Catholic thought, occurring early in our history.

St. Augustine wrote about how foolish and spiritually dangerous it is to take a position that goes against reason.  It is very unfortunate that you are unable to see that this applies to flat earth.

Flat earth is not a Church teaching.  Even you must realize that.  What the ancient Hebrews believed, may be significant to Protestants doing their personal interpretations of Scripture, but is not relevant to Catholics.  There is no good reason for you to insist on proclaiming an idea that is potentially harmful to souls.  If you want to believe the earth is flat, go ahead. There is no dogma that says you should not. But please keep quiet about it.

Your exact words were " Catholics believed in a flat-earth before the Reformation Protestants, deluded Catholics and Freemasons got a foot in the door of science and changed what Catholics traditionally believed."  This is simply not true.  Catholics had stopped believing in a flat earth by 600, which is around a thousand years  before you are claiming it happened.  Furthermore you are saying that St. Albert the Great, Doctor of the Church and Patron of natural sciences, is a deluded Catholic, since he believed the earth is a globe.
That issue is more complicated and I would need to study it more before saying anything.  It looks like you know you don't have a leg to stand on and want to change the subject.

Until someone can explain to me how this is a question of faith, this is just useless bickering.  It's a scientific question.  At least with Geocentrism, there were passages in the Bible that could be construed as supporting it.  In fact, I am a Geocentrist.  And there's certainly a pernicious side to Heliocentrism, an attempt to dethrone human beings as the pinnacle of creation and also to cast doubt upon creation itself.  But I don't see it with flat earth.

There's a reason why I bring up heliocentrism. Because Popes of the past have condemned heliocentrism. It may seem like I'm changing the subject, but I'm not. It has nothing to do with believing that I don't have a leg to stand on. That's your view.

Do you believe in heliocentrism? That the earth revolves around the sun? Because that belief has been condemned by Popes.

The deluded Catholics that I'm referring to are the ones who actively worked in scientific endeavors to push the globe earth and heliocentrism, which has led, in part to the problem with secular humanism that we see today. I'm not referring to saints who believed as such.

I have not studied the question of geo/heliocentrism enough to express an opinion.  I like to know what I am talking about.

I have, however, looked into flat earthism.  There is no reason why Catholics should not believe in a globe earth and no evidence that this belief promotes secular humanism.  And it does not make sense to say that it is OK for Saints to believe it but bad when anyone else does.

You seem to be conflating flat earth with geocentrism, but you have not established any reason for doing this.  At this point, it seems merely arbitrary.

I believe that people's personal interpretations of the Ancient Hebrews have no relevance to the Catholic Faith.  People can see anything they want in Scripture.  We need to approach it with the guidance of the Church or we will recreate the infinite nonsense of Protestants.

I already told you that the Church allows your belief in flat earth.  That does not make it prudent or helpful to talk about it.  I am not sure what you think to gain by debating it.  Do you like people telling you that you are stupid?
