here is a great article written about the issue/abuse of “separation of church and state”. it is very well written and informative without getting overly technical.

from the writings of congressman and presidential canidate ron paul: (FYI:this post does not necessairily mean an endorsement)

The entire nation seemed to condemn [the] federal court
ruling that the pledge of allegiance cannot be recited in schools.
The notion that the phrase “one nation under God” renders the
pledge unconstitutional is ridiculous to most Americans, who
strongly believe that expressions of religious belief should be
an integral part of public life. Yet although the public outcry
against this terrible ruling is understandable, the real issue
of religious freedom has not been addressed by Congress or
the media.

The judges who made this unfortunate ruling simply do not
understand the First amendment. It does not bar religious
expression in public settings or anywhere else. In fact, it
expressly prohibits federal interference in the free expression
of religion.

Far from mandating strict secularism in schools, it instead bars
the federal government from prohibiting the pledge of allegiance,
school prayer, or any other religious expression. The politicians
and judges pushing the removal of religion from public life are
violating the First amendment, not upholding it.

It’s important to recognize that the First amendment applies
only to Congress. Remember, the first sentence starts with
“Congress shall make no law…” This means that matters of
religious freedom and expression should be decided by the
states, with disputes settled in state courts. The First amendment
acts as a simple check on federal power, ensuring that the federal
government has no jurisdiction or authority whatsoever over religious

The phony “incorporation” doctrine, dreamed up by activist
judges to pervert the plain meaning of the Constitution, was
used once again by a federal court to assume jurisdiction over a
case that constitutionally was none of its business.
Similarly, the mythical separation of church and state doctrine
has no historical or constitutional basis.

Neither the language of the Constitution itself nor the legislative
history reveals any mention of such separation. In fact, the
authors of the First amendment- Fisher Ames and Elbridge
Gerry- and the rest of the founders routinely referred to
“Almighty God” in their writings, including the Declaration of
Independence. It is only in the last 50 years that federal courts
have perverted the meaning of the amendment and sought to
unlawfully restrict religious expression. We cannot continue
to permit our Constitution and our rich religious institutions
to be degraded by profound misinterpretations of the Bill of Rights.
