(CHRISTIANPOST) — The theater adaptation of a classic Christmas cartoon is at the center of a controversy in Little Rock, Ark., where an atheist group has complained about an elementary school’s plans to take its students to see the production of “Merry Christmas Charlie Brown” at a local church.

Teachers at Terry Elementary School recently sent a letter home to parents that says the play will “expose your child to Christianity” but “if you prefer your child to not attend the program they may stay at school.” The production is scheduled to be held at Agape Church on Friday, Dec. 14, during school hours, and one of the school’s teachers attends the church and is to be a part of the play.

One upset parent told KARK-TV she doesn’t want her daughter to see the play, but is letting her attend out of fear that her daughter will be singled out by her classmates. The mother also contacted the Arkansas Society of Freethinkers (ASF), which believes the school has violated the Establishment Clause of the U.S. Constitution by exposing students to a play that contains Christian themes.
