As disputes about school prayer go, the one in rural Sussex County, Del., has been nasty. It started in 2004, when Mona Dobrich, a Jewish woman, objected to a prayer spoken at her daughter’s high school graduation that included the plea that “these graduates will come to learn the truth that can only be known through knowledge of our Lord and savior Jesus Christ.”

Dobrich raised the issue during a school board meeting attended by hundreds of people. Many strongly opposed Dobrich’s viewpoint and held signs reading “Let us pray, God is listening,” and “Jesus is the light of the world.”
