Did the Christian church ever support the idea of a flat earth? And what does the Bible say about a flat earth? The myth that Christians believe, or once believed, in a flat earth, is commonly regarded as true.
However the evidence from the Bible is compelling:
Job 26:7 He stretcheth out the north over the empty place, and hangeth the earth upon nothing.
Isaiah 40:21, 22 It is he that sitteth upon the circle of the earth. (The word "circle" is translated from a word meaning "ball" or "sphere".)
There are sixteen scriptures which refer to the fact that the universe is expanding, for example:
Isaiah 40:22 ...that stretcheth out the heavens as a curtain and spreadeth them out as a tent to dwell in.

Who first invented the idea of a flat earth? And who perpetuated this myth? It wasn't Christians! See this link.
What about Galileo? He is commonly protrayed as trying to persuade a hostile church about the truth of the universe. However, "It was not a simple conflict between science and religion, as usually portrayed. Rather it was a conflict between Copernican science and Aristotelian science which had become Church tradition." For more on this conflict, see this link.
