Talk in Class Turns to God, Setting Off Public Debate on Rights – New York Times

Shortly after school began in September, the teacher told his sixth-period students at Kearny High School that evolution and the Big Bang were not scientific, that dinosaurs were aboard Noahâ..s ark, and that only Christians had a place in heaven, according to audio recordings made by a student whose family is now considering a lawsuit claiming Mr. Paszkiewicz broke the church-state boundary.
â..If you reject his gift of salvation, then you know where you belong,â. Mr. Paszkiewicz was recorded saying of Jesus. â..He did everything in his power to make sure that you could go to heaven, so much so that he took your sins on his own body, suffered your pains for you, and heâ..s saying, â..Please, accept me, believe.â.. If you reject that, you belong in hell.â.
The student, Matthew LaClair, said that he felt uncomfortable with Mr. Paszkiewiczâ..s statements in the first week, and taped eight classes starting Sept. 13 out of fear that officials would not believe the teacher had made the comments.
