Well, now I think its fascinating that someone would post something like this because they have otherwise dismissed such statements that weren't "infallible". The poster in particular has been quite vociferous against accepting any quotes that serve the flat earth at all BECAUSE they aren't infallible. In fact, quotes that reveal very specific teachings of the tabernacle for instance, are totally disregarded because a pope didn't say them.
Take for instance Methodius' statement against the pagans: “Resuming then, let us first lay bare, in speaking of those things according to our power, the imposture of those who boast as though they alone had comprehended from what forms the heaven is arranged, in accordance with the hypothesis of the Chaldeans and Egyptians. For *they* say that the circuмference of the world is likened to the turnings of a well‐rounded globe, the earth having a central point. For its outline being spherical, it is necessary, they say, since there are the same distances of the parts, that the earth should be the center of the universe, around which as being older, the heaven is whirling."
Or Cosmas' quotes against the pagans: “false and heathen doctrine of a spherical earth”.
Or even the quote from Severian of Gabala: "He made the upper heavens about which David sang: "The heaven of the heavens is the Lord's."6 This heaven forms in a certain way the upper stage of the firmament. As in any two-story house, there is an intermediate stage; well in this building which is the world, the Creator has prepared the sky as an intermediate level, and he has put it over the waters; from where this passage of David: "It is you who covered with water its upper part.“
So what's the big idea, huh? Deny, dismiss, berate, ignore, because certain quotes don't serve your purpose? Then complain there are no good quotes that show Catholics defended a geocentric flat earth? But worse, place some random quote up that MIGHT server your sentiments and take the discussion hopefully in another direction. This tactic is common among those who say such things as, "Well, we don't know the shape of the earth because God didn't tell us." And "Scripture doesn't reveal the shape of the earth and no Catholic says it does." But then they post something as if it had all the weight in the world to undermine the quotes they don't like.
About it there can be no doubt. Several people on the thread do not want to discuss with the intention of learning or gleaning information, but hearing anything they are permanently fixed against, they throw shade at anyone providing information that sheds light on the subject. Not exactly conducive to seeking the truth, but rather, a most curious and vindictive brick wall has been constructed to keep information from entering the discussion.
