In Dearborn, Mich., home to over 40,000 Americans of Arab descent, some Muslim parents have complained about flyers handed out at public schools advertising an Easter egg hunt at a local Presbyterian church.

The Muslim parents assert that the flyers – emblazoned with the word “Eggstravaganza!” – violate the separation of church and state widely ascribed to the First Amendment’s Establishment Clause, reports the Detroit Free Press.

Students at three Dearborn elementary schools received the flyers. A large number of Muslim students attend the schools.

The “Eggstravaganza!” is scheduled to take place on April 12 event at Cherry Hill Presbyterian Church in Dearborn.

The flyer urges students to RSVP “to secure your free spot,” note the Free Press. The associated imagery includes a festive bunny and some eggs.

The event will feature a traditional Easter egg hunt as well as an egg toss and a relay race.

“It really bothered my two kids,” parent Majed Moughni told the Free Press. “My son was like, ‘Dad, I really don’t feel comfortable getting these flyers, telling me to go to church. I thought churches are not supposed to mix with schools.”
