I decided to cheat a bit here and offer a list of quotations. The quotations from the Supreme Court (towards the bottom) are of particular importance as it is the function of the Supreme Court to interpret, explain, and rule upon the meaning of the Constitution. Sorry guys but the Supreme Court has ruled repeatedly that there is indeed a separation of church and state.

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof, or abridging the freedom of speech, or of the press, or the right of the people peaceably to assemble, and to petition the government for a redress of grievances."--First Amendment to the U.S.A. Constitution
As the government of the United States of America is not in any sense founded on the Christian Religion--as it has itself no character of enmity against the law, religion or tranquility of Musselmen [Muslims], ... - "Article 11, Treaty of Peace and Friendship between The United States and the Bey and Subjects of Tripoli of Barbary," 1796-1797.
E PLURIBUS UNUM ... is the Latin motto on the face of the Great Seal of the United States; .... This phrase means one out of the many. It refers to the creation of one nation, the United States, out of 13 colonies. It is equally appropriate to today's federal system. Benjamin Franklin, John Adams, and Thomas Jefferson, members of the first committee for the selection of the seal, suggested the motto in 1776. It can be traced back to Horace's Epistles [65-8 BCE]. Since 1873, the law requires that this motto appear on one side of every United States coin that is minted. (Donald H. Mugridge,World Book Encyclopedia, Volume 6 (E), Chicago: Field Enterprises Educational Corporation, 1976, p.2. "E Pluribus Unum" has appeared on most U. S. coins, beginning in the late 1790s. The motto "In God We Trust" did not appear on any U. S. coin until 1864, when "Its presence on the new coin was due largely to the increased religious sentiment during the Civil War Crisis," according to R. S. Yeoman, A Guide Book of United States Coins, 38th ed., Racine, Wisc.: Western Publishing Co., p. 89. The religious motto did not appear regularly on U. S. paper money until the 1950s.)
Many of the states [in the period between the Revolution and the adoption of the U. S. Constitution], in order to obviate any suggestion of a religious establishment, prohibited all clergymen from sitting in the legislation. - Gordon S, Wood, The Creation of the American Republic
In the mid-eighteenth century, America had a smaller proportion of church members than any other nation in Christendom. American religious statistics are notoriously unreliable, but it has been estimated that in 1800 about one of every fifteen Americans was a church member ... (Richard Hofstadter, Anti-Intellectualism in American Life
Christianity is not established by law, and the genius of our institutions requires that the Church and the State should be kept separate....The state confesses its incompetency to judge spiritual matters between men or between man and his maker ... spiritual matters are exclusively in the hands of teachers of religion. - U. S. Supreme Court, Melvin v. Easley
[Chief Justice Morrison Waite, in Reynolds vs. U.S., a Supreme Court decision in 1878] cited Madison's Memorial and Remonstrance of 1785, in which, said Waite, "he demonstrated "that religion, or the duty we owe the Creator,' was not within the cognizance of civil government." This was followed, said Waite, by passage of the Virginia statute "for establishing religious freedom," written by Jefferson, which proclaimed complete liberty of opinion and allowed no interference by government until ill tendencies "break out into overt acts against peace and good order." Finally, the Chief Justice cited Jefferson's letter of 1802 to the Danbury Baptist association, describing the First Amendment as "building a wall of separation between church and state." Coming as this does, said Waite, "from an acknowledged leader of the advocates of the measure, it may be accepted almost as an authoritative declaration of the scope and effect of the amendment thus secured." (Irving Brant, The Bill of Rights: Its Origin and Meaning, Indianapolis: Bobbs-Merrill Co., Inc., 1965, p. 407.)
Supreme Court Justice Rutledge stated in 1947 that the First Amendment was not designed merely to prohibit governmental imposition of a religion; it was designed to create "a complete and permanent separation of the spheres of religious activity and civil authority...."
"the words of Jefferson, the clause against establishment of religion by law was intended to erect "a wall of separation between church and State." - Justice Hugo Black, U. S. Supreme Court
The First Amendment has erected a wall between church and state. That wall must be kept high and impregnable. We could not approve the slightest breach. (Justice Hugo Black, U. S. Supreme Court, Everson v. Board of Education
The preservation of the community from division conflicts, of government from irreconcilable pressures by religious groups, of religion from censorship and coercion however subtly exercised, requires strict confinement of the state to instruction other than religious, leaving to the individual's church and home, indoctrination in the faith of his choice.... The extent to which this principle was deemed a presupposition of our Constitutional system is strikingly illustrated by the fact that every state admitted into the Union since 1876 was compelled by Congress to write into its constitution a requirement that it maintain a school system "free from sectarian control." ... (Justice Felix Frankfurter, U. S. Supreme Court, in McCollum v. Board of Education
Government in our democracy, state and national, must be neutral in matters of religious theory, doctrine and practice. It may not be hostile to any religion or to the advocacy of nonreligion; and it may not aid, foster, or promote one religion or religious theory against another or even against the militant opposite. The First Amendment mandates governmental neutrality between religion and religion, and between religion and nonreligion. (U. S. Supreme Court, Epperson v. Arkansas
