It was written in the language, which was at that time the world language, like English is now. I don't mean to say, that all of us should study these languages. Far from it. Still, as scientists who pride themselves of having the ability to get a thorough understanding we should realize those things, and act accordingly. Often we act as if our scientific studies have no relation with our faith.
Nothing is further from the truth.
We start studying with certain biases in our understanding of the world. That means that we base our studies on possibly un-biblical ideas. I'll give some examples, but I do not want them to be taken as my final thinking, nor as grounds for accusations of heresy. The bible talks to all people, not just to scientists. That goes much further then Galileo's thinking.
