First off, the school this girl goes to is a PUBLIC high school. In McCollum v. Board of Education Dist. 71, the Supreme Court ruled that religious instruction violated the 1st amendent's establishment clause of freedom of religion. Last time I checked, Jews, Muslims, Hindus, Pagans, and Atheists go to public school as well as christians, so forcing everyone in PUBLIC high school to read the bible violates the 1st amendment right to freedom of religion. If you want your child to read a bible in school, go to a PRIVATE christian high school.
Second, while the founders were largely protestant, the Constitution was written to separate church and state. No where in the Constitution is god mentioned. The founding fathers never intended for christian teachings to be the law of this land. If they did, it would have been explicitly written in the constitution and the 1st amendment would not have granted religious freedom because christianity would have been the law.
Side note: Did you read the very last sentence of that article of yours?
"Many Christians have stood up and said they agree with me too," Strivelli said. "Because, as much as they may like the Bible, they don't want Jehovah's Witnesses coming in with Watch Tower (magazines) or Catholics coming in and having them pray the Rosary."
Based on what I know from your previous questions, you would not want jehovah's witnesses influencing your children.
