Religion as defined by Webster's Seventh New Collegiate Dictionary: 1) The service and worship of God or the supernatural, 2) commitment or devotion to religious faith or observance, 3) a personal set or institutionalized system of religious attitudes, beliefs and practices; 4) a cause, principle, or system of belief held to with ardor and faith.
Congress as defined by Webster's Seventh New Collegiate Dictionary: The supreme legislative body of a nation and especially of a republic.
So now insert the definitions into the First Amendment and this is how it reads: The supreme legislative body of this nation shall make no law respecting an establishment of 1) The service and worship of God or the supernatural, 2) commitment or devotion to religious faith or observance, 3) a personal set or institutionalized system of religious attitudes, beliefs and practices; 4) a cause, principle, or system of belief held to with ardor and faith, or prohibiting the free exercise of 1) The service and worship of God or the supernatural, 2) commitment or devotion to religious faith or observance, 3) a personal set or institutionalized system of religious attitudes, beliefs and practices; 4) a cause, principle, or system of belief held to with ardor and faith; 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.
It would appear that only the misinformed could read the First Amendment any other way.
