Kalispell, MT -

High school choirs from Kalispell and Whitefish plan to participate in a Christmas concert at the Mormon church in Kalispell despite protests from the American Civil Liberties Union and the Freedom From Religion Foundation.

Officials from Flathead and Glacier high schools in Kalispell and Whitefish High School say the choirs were invited to participate in the "Peace on Earth Community Christmas Celebration" Thursday and Friday and plan to do so.

The ACLU and Freedom From Religion Foundation sent letters to the schools saying that participation in the religious event gives the appearance the schools were endorsing or advancing a specific religious message or denomination.

School officials have said student participation in the Christmas event is voluntary. The Whitefish choir is an extracurricular program.
