"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."
The word used "respecting" is pretty much the same word that is used in the Bible. "For God is no respecter of persons." When it is used in this sentence. He is moreless telling us that it doesn't matter who you are, he will not choose one person over another by playing favorites.
After much examining of the first amendment, my intake is that Congress has to treat all branches of Christianity equally and not favor one sect over another. Nor can congress declare the United States one branch of Christianity.
However, many questions arise about the true meaning because of the fact that the Bible was part of the school curriculum until June 1963. If the "founding fathers" who signed this constitution didn't want prayer or Bible reading taught in our schools, then surely they would not have allowed it nor would the latter Presidents have allowed this for over 200 yrs. Next is the history of our schools.
