He isn't, of course; he was a liberal German Lutheran. But he's been "adopted" into the evangelical world, just like C.S. Lewis. But, he wasn't always welcomed by evangelicals; I was warned not to read him in the early-mid 1970s—I was told he was "dangerous." Ain't that the truth! But not for the reasons that person had in mind...
That change got me thinking about changes in general. Here's a few that came to mind:
Did you know that the "Pledge of Allegiance" was written by a socialist?!
Did you know that the phrase "under God" in the Pledge was added in the 1950s to distinguish "godly" America from the "godless" Soviet Union?
Did you know that the Puritans were against the celebration of Christmas? So much for putting the Christ back in Christmas, eh?
Did you know that "In God we trust" has only appeared on paper money since 1957? Check it out!
