Religion

Most evangelical denominations don't spend a lot of time studying Matthew. They're more interested in Paul's letters. The Beatitudes point out too much for folks who think they're "all that." That makes them unpopular with uncharitable people.

The Old Testament 10 Commandments, on the other hand tell people what not to do, mostly. Jesus, according to what he was supposed to have said, took a more proactive position, and described what good people ought to do, instead. Trouble is that, in many cases, he told people they ought to do things they didn't really want to do, since that would often mean going against their own desires.

It's a paradox.
