Theoretically, in the USA, the national legislative body has no power to deal with religion.

Nevertheless, the nation's official motto is "In God we trust".
Since 1978, an association of freethinkers named the Freedom From Religion Foundation, based in Wisconsin, has been striving to erode the grip of God's trustees. Among other things, they've got around to designing what look like stained-glass windows of a new kind. Here's their Dawkins model:
The word "trust", with financial connotations, can be found in French dictionaries. The presence of this verb on US banknotes lends weight to the view that the power of the dollar is, in some mysterious way, divine. This money is backed by God, as it were. I used to feel the same way about the basic monetary unit of modern Israel, the shekel.
Here in Europe, we've got a lot of work to do before the euro shines divinely like a piece of silver warmed by the hand of God. The underlying problem, of course, is that the mythological pagan creature Europa was not exactly the kind of female who would be welcomed into the home of a normal God-fearing family. As for the idea of "In Zeus we trust", this just wouldn't sound convincing to a serious banker.
