The state legislature enacted a statute requiring that every high school English class use the Psalms of the Bible as the sole basis for teaching poetry. The preamble to this legislation recited: "We find and declare that the Psalms of the Holy Bible are great poetry independent of their religious significance, and that the academic interests of the students of this state will be best served by using the Psalms as models of outstanding verse." An atheist objects to the use of religious materials in his high school-age daughter's classroom, so he brings an action in federal court to enjoin enforcement of the statute.
