Are you unable to produce a single reference to the Church teaching that the Earth is flat? Conjecture, reasoning, and speculation aside, I'm sure you must have at least one authoritative reference you can share
Your attempts to debunk the truth are almost amusing. Almost. Not only have I provided multiple references, clearly Catholic teaching, you take the time to put up one quote. Not only was there only ONE, it didn't prove your point, but mine. Your pertinacity in error is evident to all.
