On the Thursday night after Donald Trump won the presidential election, an obscure but telling celebration unfolded inside a converted barn off a highway stretching through the cornfields of Lancaster County, Pennsylvania. The place was called Gateway House of Prayer, and it was not exactly a church, and did not exactly fit into the paradigms of what American Christianity has typically been. Inside, there were no hymnals, no images of Jesus Christ, no parables fixed in stained glass. Strings of lights hung from the rafters.
