Can somebody show me where in the Constitution the words "Christian nation" appear?

They're not and they ignore the first amendment. Or 'interpret' it as meaning we have freedom of Xian sect (eye roll)
The poor fools can't differentiate between The Declaration and the Constitution and conceitedly assume the words 'our Creator' refer directly to the deity of the Xians, Jews, Muslims and ignore the fact that the Treaty of Tripoli which expressly denies that we are a Christian Nation was signed UNANIMOUSLY or that T. Jefferson, our third pres., had quite a few negative remarks about Xianity specifically.

I think scooter..is just trying to be an antagonist....Show more

Our Constitution was not written for a church it was written for a nation. But the majority of the writers of the Constitution were God fearing men and based the writing of the Constitution from the Bible. This can not be denied. Unless you are ignorant of the history surrounding the writing of the document. Many of the writers were Pastors, many started theological seminaries, christian collages and the list could go on. So the majority of the writers of the Constitution believed in God and used the bible (and they say so in their own words read the historical documents) as a guide for the writing of it but they were writing a document for a nation of all those who believe and those who do not believe and the freedom to do just that, they were not trying to form a church with this document. (although many did do that)

EDIT: Annonie (?) you have your fact wrong. It was not Jefferson it was Washington and please read the whole thing and know why it came about.
The 1797 treaty with Tripoli was one of the many treaties in which each country officially recognized the religion of the other in an attempt to prevent further escalation of a "Holy War" between Christians and Muslims. Consequently, Article XI of that treaty stated:
As the government of the United States of America is not in any sense founded on the Christian religion as it has in itself no character of enmity [hatred] against the laws, religion or tranquility of Musselmen [Muslims] and as the said States [America] have never entered into any war or act of hostility against any Mahometan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries.
This article may be read in two manners. It may, as its critics do, be concluded after the clause "Christian religion"; or it may be read in its entirety and concluded when the punctuation so indicates. But even if shortened and cut abruptly ("the government of the United States is not in any sense founded on the Christian religion"), this is not an untrue statement since it is referring to the federal government. While the Founders themselves openly described America as a Christian nation they did include a constitutional prohibition against a federal establishment; religion was a matter left solely to the individual States. Therefore, if the article is read as a declaration that the federal government of the United States was not in any sense founded on the Christian religion, such a statement is not a repudiation of the fact that America was considered a Christian nation....Show more

Contrary to the claims of many accommodationists, virtually nothing in the Constitution references Christian thought and morality. The only explicit mention of religion is the article VI declaration that "no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States." Otherwise, the Constitution is wholly concerned with the secular issues of defining federal power, and distributing that power among the various branches of government....Show more

In a joint resolution requesting the President proclaim 1983 as the "Year of the Bible". it declared:
the Bible, the Word of God, has made a unique contribution in shaping the United States as a distinctive and blessed nation and people. Deeply held religious convictions springing from the Holy Scriptures let to the early settlement of our nation...Biblical teachings inspired concepts of civil government that are contained in our Declaration of Independence and the Constitution of the United States(Public Law 97-280)....Show more

I can't. I can however show you the Treaty of Tripoli, where Jefferson explicitly states that the US is in no way a christian nation....Show more
