For some reason, the most vocal Christians never seem to mention The Sermon on the Mount (Beatitudes, Matthew 5).
But they often demand that the Ten Command-ments be posted in public buildings.
It, by the way, is from Moses, not Jesus.
I haven't heard them demand that The Sermon on the Mount be posted anywhere.
As in
“Blessed are the merciful” posted in a courtroom. Or Congress. Or the White House?
