You noticed that eh? And I did know where it came from when I used it.
When I was young, I intended to be a Southern Baptist missionary, and even studied for it in college for a while. But when I discovered that not everything I studied as "truth" was actually true (things like evolution), then I was forced to decide that none of it was true.
This is the tragedy of teaching creationism and literal old-testament history. There's just no way to rationalize it with the physical evidence in hand. So what to believe, an old book, with zero physical evidence behind it? Or physical evidence I can hold in my hand?
As far as I can see, the Catholic Church has a sustainable philosophy behind their faith. They make no claims that any part of their faith contradicts physical evidence found in science (at least they do that today). Therefore Catholics are free to believe in their interpretation of God without fear that He will ever be disproven by science.
The creationists aren't nearly as bright.
So you get to pick which denominations are acceptable and which are not? Is that your idea of religious freedom? If your "scientific" theory says that the Bible is mythology and you force that as the official government position then you have just ended religious freedom -- that's not a neutral position.
