Separate question, cassini ... do you believe in the mainstream / conventional explanation for "gravity"? If not, what do you believe on a globe model causes people and objects to stick to the "bottom" of the ball earth?
I think that's one of the things we need to recognize in reading the Church Fathers. They had no notion of "gravity", but merely of density, and that's why they had the debate about whether the earth could be suspended in the middle of the waters or would have to sink to the "bottom" of the world / universe, as detailed by St. Augustine. If, then, without a notion of gravity, they believed that the surface of the earth that people walk on is a ball, how would they explain people and objects adhering to the bottom of the ball, when they appear to have had absolute notions of up and down and no concept of gravity?
I know that Dr. Sungenis is fond of quoting St. Hildegard, but if you actually look at what she wrote, while she considered the earth to be shaped roughly like an egg, she also explicitly stated that the bottom part of this egg consisted only of Sheol and the Deep, which would include a hollow within the earth below the water line of the deep, and in which people continued to be right-side up ... and not sticking to the bottom of the globe by some as-yet-untheorized "force".
BTW, I think that the mainstream notion of gravity as being some independent force is total bunk, but that it's more related to electromagnetism and the flow of ether. I am, however, coming around to the notion that there's no such thing as completely empty space. Of course, the notion of movement needs to be explained since movement would require the displacement of matter into some other location that was not occupied by said matter before, which in turn would have to displace other matter, etc. So at some point there has to be an absence of matter for something to move into. I do disagree with the Sungenis argument from nothing being unable to exist, since that non-nothingness doesn't need to be material, and I believe that the concept of movement does require some "empty" space to exist somewhere, at least relatively empty, empty of matter.
