You may have seen the following in the Atheosphere already. If you have, it's worth reading a second time, particularly if you like horror stories. If you haven't seen it yet, you'd better read it twice, carefully. Then go look at yourself in the mirror to check if your hair is standing on end.
It's H. Res. 847, which passed in the United States House of Representatives yesterday by a vote of 372 to 9 (you did not read that incorrectly). Friendly Atheist, where I first learned about this piece of crypto-theocratic garbage, lists the names of the brave nonet who voted against it.
This is a resolution, which does not have the force of law. Technically, it's just self-serving babble by the 195 Democrats (stop doubting yourself; you read that right, too) and 177 Republicans who voted to pass it.
However, the House has now formalized, in whatever small way, four very scary ideas. They're not stated explicitly, but implied, although the meanings are clear nonetheless. In the following list, the numbers correspond to the highlighted portions of the document that support each idea. (The highlighting and numbering are mine.)
America is a Christian nation: 1, 2, 3, 5
America was founded as a Christian nation: 3, 5
Christians in America are being assailed by secularists and need support: 4, 6
The United States has a mission to defend worldwide Christianity against its enemies: 2, 6, 7
RESOLUTIONRecognizing the importance of Christmas and the Christian faith.
Whereas Christmas, a holiday of great significance to Americans  and many other cultures and nationalities, is celebrated annually by Christians throughout the United States and the world;
Whereas there are approximately 225,000,000 Christians in the United States, making Christianity the religion of over three-fourths of the American population; 
Whereas there are approximately 2,000,000,000 Christians throughout the world, making Christianity the largest religion in the world and the religion of about one-third of the world population;
Whereas Christians identify themselves as those who believe in the salvation from sin offered to them through the sacrifice of their savior, Jesus Christ, the Son of God, and who, out of gratitude for the gift of salvation, commit themselves to living their lives in accordance with the teachings of the Holy Bible;
Whereas Christians and Christianity have contributed greatly to the development of western civilization;
Whereas the United States, being founded as a constitutional republic in the traditions of western civilization, finds much in its history that points observers back to its roots in Christianity ;
Whereas on December 25 of each calendar year, American Christians observe Christmas, the holiday celebrating the birth of their savior, Jesus Christ;
Whereas for Christians, Christmas is celebrated as a recognition of God's redemption, mercy, and Grace; and
Whereas many Christians and non-Christians throughout the United States and the rest of the world, celebrate Christmas as a time to serve others: Now, therefore be it
Resolved, That the House of Representatives--
(1) recognizes the Christian faith as one of the great religions of the world;
(2) expresses continued support for Christians in the United States and worldwide; 
(3) acknowledges the international religious and historical importance of Christmas and the Christian faith;
(4) acknowledges and supports the role played by Christians and Christianity in the founding of the United States  and in the formation of the western civilization;
(5) rejects bigotry and persecution directed against Christians, both in the United States and worldwide;  and
(6) expresses its deepest respect to American Christians and Christians throughout the world. 
Be warned: Take nothing for granted.
Now that you've read the resolution, I urge you to go back to the third paragraph and look at the number of yea votes given by members of each party. Please remember those numbers the next time you're tempted to spout off that Democrats are somehow safer for atheists and other secularists than Republicans. While Democrats may not be pushing forward such blatant theocrats as Romney, Huckabee, and Paul as presidential choices, many a Democratic heart still beats with the same theocratic zeal that made William Jennings Bryan the party nominee three times.
