Separation of Church and State
The
reason for our government from the
Declaration of
Independence:
{'The why?" if you will, as contrasted with 'The how? of our Constitution}
In Congress, July 4, 1776
The unanimous Declaration of the thirteen united States of America
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just Powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new guards for their future security — Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. — The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let facts be submitted to a candid world....
The
why of our nation and government is
to secure the unalienable rights humans have been endowed with
by our Creator.
Our rights do not come from the government. If the government forgets this, and says our unalienable rights come from the Government, the Government, in effect, makes itself
to be God.
Keeping the government from usurping God's place is the true meaning behind the wall of separation between Church and State, imo. That is why the First Amendment says:
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.
For Congress to make such a law would be encroaching on God's territory, and upon individual conscience, something endowed upon us by our Creator, making the Government into god.
Eh, no... to me that smacks of hypocrisy and special privelege. Law in this country, depsite its dubious origins, has no business being Biblical, just as it has no business being derived from the Koran or the Tao Te Ching.
