I had a law school professor who would say whenever someone sneezed: "God bless you, and I say that as a private individual and not as a government employee." She thought she was pretty witty, haha.
And he that hath lyberte ought to kepe hit wel / For nothyng is better than lyberte / For lyberte shold not be wel sold for alle the gold and syluer of all the world. -Caxton's edition of Aesop's Fables, 1484
"In God We Trust". One has to wonder if God would have wanted his name or reference on something so vile. Maybe that's why the dollar is doomed. I have (almost) read the Bible cover to cover (missed a few pages) and I have yet to find where GOD has indicated anywhere that he would back the dollar. Money is one of the most misunderstood symbols of modern times. In my opinion when the concept of a paper currency was conveived the creators used the symbol "IN GOD WE TRUST" as a way to create legitimacy for the "paper dollar". This might have been sufficient for a faith based society with a moral and God fearing people. Today this is far from the case.
I don't think the references to God has anything to do with religion.
The folks who founded this nation knew the existence of God is a matter of fact.
The adversity to religous influence refers to organizational church control. They would avoid refrencing "the anglicans we trust" or something like that.
But it's clear that we are endowed by our creator with freedom, and the responsibility that comes with exercising free will.
Church and government can only remove our God given freedom.
In God we trust is a phrase that recognizes the powers of church, government and money are totally subordinate to the authority of Almighty God.
Whether or not The Almighty would approve of the phrase being stamped on our currency is another matter. Someday that truth will be revealed and this thread will seem to have been a waste of time.
Why would FIAT have in God we trust on it? If we trusted in God we would not laden ourselves, children, grandchildren, and all those who use these notes for commerce with the debt it creates. If we believed in God we would use a form of currency that is not based on the debt and work of others.
