Protestantism — like the rest of the world — continues to evolve. Compared to fairly recently, the country looks vastly different. Less than four decades ago, President Ronald Reagan declared 1983 the “Year of the Bible.” It was no great shock: In the early ’80s — as reported by the Pew Research Center — 89% of Americans identified as Christian. Adherents to other religions totaled 4% while only 7% subscribed to no religion at all. Since then, faith has seen a radical decline. As observed by Gallup, 2019 marked the first year American church membership dropped below 50%. U.S. church membership was 73% when Gallup first measured it in 1937 and remained near 70% for the next six decades, before beginning a steady decline around the turn of the 21st century.
