Here’s a roundup of key cases with church-state implications the Supreme Court will decide during the term.

During the 1950s, the United States was locked in an ideological struggle with 'godless communism,' and adding a reference to God to the Pledge of Allegiance was seen by many as a good tactical move.

"The Supreme Court should not force the City of Boston to fly a Christian flag at city hall," said Rachel Laser, president and CEO of Americans United. "It was bad enough when the Court ignored church-state separation by allowing a towering Christian cross to remain on public land in Bladensburg, Maryland. But to force any American city to erect new religious displays would not only undermine the foundational principle of church-state separation, it would play right into the hands of Christian nationalists who want the government to force everyone to live by their beliefs."
