美國憲法第一修正案里說:「國會不得制定法律,來確立或禁止某種宗教;也不能限制言論、出版自由;也不能限制抗議政府不公而集會請願的權利」(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)[1]。這一段是最接近所謂「政教分離」法律條文,它沒提任何「Separation of State and Church」,完全沒有。
