Moderate Christian apologists have done an astonishingly good job of sweeping under the rug the fact that the OT does indeed describe a flat, disc shaped Earth covered by a solid dome called the firmament.
So much so that when I attended a Christian private school, we were taught that scientists in ancient times were the ones who thought Earth was flat even though the Bible said it's round. (Nevermind that science did not exist then.)
What they mean by "round" is a single verse which says Earth is a circle. But the Hebrew word for circle used in that verse does not mean sphere. There was a different word meaning ball shaped they might've used instead, but they didn't.
Further, the circle is said to have been inscribed upon the face of the deep as though with a compass. There's a medieval painting of Jesus doing this (seen below). It is clear from this context that a flat circle was the intended meaning.
This is to say nothing of the plentiful verses describing the firmament, with stars physically embedded in it, trap doors opened to let the waters above fall through as rain, and so on.
I was never taught about any of that from other Christians. Probably they were not, themselves, aware of those verses because nobody ever taught them about it either.
So it is that in the comments of any article or video about flat eathers, there's invariably a few moderate Christians laughing at the absurdity of it, then qualifying it with "but the Bible does not say Earth is flat, that's a heresy which originated in the middle ages", another apologist fabrication.
They can point to 2 or 3 Christian scholars from the middle ages who accepted a round Earth and try to extrapolate from that to all Christians being aware of it, and a spherical Earth therefore being the intended meaning of the verses in scripture which describe cosmology.
They have also argued that the translator William Tyndale (responsible for translating the Bible into English) had the opportunity to correct those mistakes, and would have if they actually were mistakes, in order to make the Bible more defensible. (This assumes that Tyndale would've been sufficiently impious to make his own independent edits to the holy book of his own religion, even though scripture emphatically says never to do that.)
All in all, moderate Christians have done an incredible job of making sure almost no Christians anywhere (except flat earth YECs) are even aware that ancient Israelite cosmology did in fact include a flat Earth and was geocentric by repeating lies which they may well believe themselves.
It's hard to get this information out to the public because anywhere that Christians are in a position to censor it, they do. Even here on Steemit, trying to set the record straight often results in flagging.
This effect is even more pronounced in the mainstream media where flat earthers are lampooned as kooks with a false, heretical view of what the Bible teaches when in fact they're among the few Christians who are aware of and accept Biblical cosmology.
Recently I had the good fortune of meeting a clever, extremely thorough Biblical scholar and polemicist whose primary focus is getting the word out that the Bible absolutely does describe a geocentric, flat Earth cosmology in spite of what moderate Christian apologists commonly claim.
I received his permission to repost his videos here so they can be viewed by a larger audience, and will be sharing them with you little by little as my posting schedule permits. Now, without further delay, part 1: "All the kingdoms of the world in a moment of time"
