The Ron Paul Library has some information on this:

"In case after case, the Supreme Court has used the infamous "separation of church and state'' metaphor to uphold court decisions that allow the federal government to intrude upon and deprive citizens of their religious liberty. This "separation" doctrine is based upon a phrase taken out of context from a letter written by Thomas Jefferson to the Danbury Baptists on January 1, 1802. In the letter, Jefferson simply reassures the Baptists that the First amendment would preclude an intrusion by the federal government into religious matters between denominations. It is ironic and sad that a letter defending the principle that the federal government must stay out of religious affairs. should be used two hundred years later to justify the Supreme Court telling a child that he cannot pray in school!
The Court completely disregards the original meaning and intent of the First amendment. It has interpreted the establishment clause to preclude prayer and other religious speech in a public place, thereby violating the free exercise clause of the very same First amendment. Therefore, it is incumbent upon Congress to correct this error, and to perform its duty to support and defend the Constitution. My legislation would restore First amendment protections of religion and speech by removing all religious freedom-related cases from federal district court jurisdiction, as well as from federal claims court jurisdiction. The federal government has no constitutional authority to reach its hands in the religious affairs of its citizens or of the several states."
