are you really saying that the flat earth people represent the majority of Christians?Here's my answer:
No, not at all. Only the ones who take the Bible literally.
Very few do. Many say they do, but ask them if they believe snow and hail come from storehouses in the sky, as clearly stated in the book of Job, and they say "that bit's metaphorical". Yet Adam and Eve is not. Neither is the Great Flood, though that depends on the existence of a Firmament with valves in - the ""Windows of Heaven" to let the Waters Above in.
Martin Luther had it right. Either you can believe in scripture as inerrant and literal, or you can rely on "natural Philosophy" - science -, observable facts and reason. The two ideologies are irreconcilable. He therefore rejected reason and natural philosophy.
Natural philosophy because it was wicked,as it contradicted scripture. Reason because while it sometimes supported scripture, it just as often subverted it, it could never be relied on to tell you what you wanted to hear. It was, he said, a whore in that regard. The greatest enemy Faith has.
"Scripture simply says that the moon, the sun, and the stars were placed in the firmament of the heaven, below and above which heaven are the waters...
It is likely that the stars are fastened to the firmament like globes of fire, to shed light at night... We Christians must be different from the philosophers in the way we think about the causes of things. And if some are beyond our comprehension like those before us concerning the waters above the heavens, we must believe them rather than wickedly deny them or presumptuously interpret them in conformity with our understanding."
- Martin Luther, Luther's Works. Vol. 1. Lectures on Genesis
“Reason is a whore, the greatest enemy that faith has; it never comes to the aid of spiritual things, but more frequently than not struggles against the divine Word, treating with contempt all that emanates from God.”
- Martin Luther
He was quite right. Reason will only tell you how things are, not how you know them to be through Faith alone.
To take as one example, the facts say that Herod died in 4BC, and that Quirinius became governor of Syria in 6CE, ten years later. The Bible says that Christ was born during Herod's reign, when Quirinius was governor of Syria.
Reason would point out the contradiction. But Faith says the bible cannot by definition be erroneous or contradictory, so Reason must be abandoned.
Christ was born before 3BC, and also in 6CE, And if ( these facts) are beyond our comprehension we must believe them rather than wickedly deny them or presumptuously interpret them in conformity with our understanding.
