As I stated before there are multiple times where the bible tells people that the Earth is flat
"It is he who sits above the circle of the earth, and its inhabitants are like grasshoppers; who stretches out the heavens like a curtain, and spreads them like a tent to dwell in" Is. 40:22"
Notice the word circle, not sphere, one is 2 dimensional and one is 3, a perfect god would not and should not make the error of comparing a sphere to a circle. Also god shouldn't be cryptic, ironic, etc. If the price of me being wrong is eternal damnation, you better have some DAMN good instructions.
Don't be historically ignorant - The protestant reformation, it scared people half to death, the reason being is that protestants and catholics were spreading the idea that if you believed in the opposition you are dammed. Saying that christianity doesn't preach interpretation superiority is proven false time and time again by history.
