There’s a lesson in this. Gov. Steve Beshear hoped to stimulate his state’s economy by offering tax breaks to a planned Noah’s Ark theme park with a 510-foot ark replica and other Old Testament attractions. But the Biblically proportioned ship has run aground against the Constitution’s prohibition of mixing matters of church and state. The park’s discriminatory hiring practices — requiring creation-belief statements and “salvation testimony” from potential employees — mean it won’t be netting the $18 million of state largess.
