Everyone needs to stop making arguments from translations. It's becoming highly annoying. Only the Latin represents the teaching of the Church. Every translation, to some extent, involves an interpretation.
But it's a simple fact that even if the Fathers were to have unanimously held that the earth is flat (and some Church Fathers did not), that does not by itself reveal a DOGMATIC consensus. There would have to be some notion that this was taught by the Church and handed down from the Apostles as part of the Deposit of Revelation.
All the quotes I have seen from the Church Fathers do not indicate anything more than that they are OPINING in favor of flat earth. I get annoyed when people keep using the word "taught" ... that such-and-such a Father "taught" flat earth. Saying or writing or thinking something doesn't necessarily rise to the level of teaching it.
Opining seems less accurate of a term because the Father's writings are always valuable. Even when they opine they are reasoning at least and teaching at best, (unless of course, it contradicts Church teaching). Truth from Scripture and Tradition is imparted to us by the Church. This is a centuries long process. When searching for truth in any age, since only one thing is true, what is contrary must be false. These threads on flat earth reveal the Church's position in a myriad of ways. But for those who cannot accept some, at the very least collectively, it shows a trajectory. Can the Church lead us in a direction and it not be 100% true? Metaphysics and cosmology shape our road to salvation, because they affect our bearings and our view of God and the world. Besides positive proof from Scripture, Fathers and even science, there is plenty of negative proof to assist in drawing a conclusion. The Church condemned the pagan heliocentric model. Seems in the meantime, the Church will war with false science to show the masses what She's been saying all along, and to more fully reveal the specifics of our origins first contained in God's Word.
