That sounds like some creative interpretation.
It was well known in antiquity that the earth was round, they even managed to calculate it‘s radius. (as well as the size and distance of the noon and the sun).
The idea that everything was made up of 4 elements (or a rather a combination of those) also assumed a round earth. Early things are heaviest and sink to the bottom, water is lighter than earth, air lighter than water and fire is lighter than air (that’s why the stars, made up of fire, are at the very top)
The church never disputed the earth being round.
They were pretty adamant about it being the center of the cosmos though, with the sun orbiting it.
FE “theory” often contains biblical references such as “the firmament” which if you try to ask what that is you won’t really get a clear explanation. I can’t stress enough that zero of it is remotely coherent.
