Of course, the ACLU and other left-leaning folks want to erase all these vestiges of our Bible-respecting history --in the name of church-state separation --so they say.
However, we never had a theocracy, meaning a state-church as the gov't. We aren't advocating any such thing now. But right and wrong, encoded into laws, are determined by majority rule, whether or not religious beliefs --OR humanistic/atheistic beliefs --shape people's views of right and wrong. The culture war is about whose worldview will determine the laws.
Religious people have as much right as the irreligious to try to influence policy and law --based on their convictions and beliefs. Separation of church and state does not preclude such influence by the religious --or the irreligious.
We have been a Judeo-Christian nation because most of the citizens of the U.S. were at least nominal Christians and believers in the Bible --or at least believers in a Supreme Being. The corporate belief in the God of the Bible has shaped our national character such that we are the best place in the world to live. If you don't think so, you are welcome to go where things are more to your liking --maybe Siberia, Cuba, No. Korea or China.
The 3rd verse of our national anthem:
O thus be it ever
When free men shall stand
Between their loved homes
and the war's desolation;
Blest with victory and peace,
May the Heav'n-rescued land
Praise the power that hath made
And preserved us a nation!
Then conquer we must,
When our cause it is just!
And this be our motto,
"In God is our Trust!"
And the star spangled banner in triumph shall wave
O'er the land of the free --and the home of the brave!
by Francis Scott Key, 1814
"God is not willing that any should perish, but that all should come to repentance and have eternal life."--the Bible
