The American Humanist Association this week filed a lawsuit in federal court in Maryland calling for the removal of Bladensburg’s 40-foot tall Memorial Peace Cross, which honors men from Prince George’s county who died during World War I.

The association and three individual plaintiffs contend that the cross, which is on state property, violates the constitutional principle of the separation of church and state. The cross was dedicated in 1925.

The lawsuit states that the humanist association is an organization that advocates progressive values and equality for humanists, atheists, and freethinkers. One of the individual plaintiffs, Steven Lowe, of Washington, believes the cross “associates a Christian religious symbol with the state and gives the impression that the state supports and approves of Christianity, as opposed to other religions,” the suit says.
