The Sermon on the Mount is the cornerstone of Christianity. Not paul or timothy, or some cherry-picked quotes from the old testament, without the rest of it, I might add. The assholes who do this never even follow Leviticus or Deuteronomy.
People like the cult Southern Baptists have no Sermon on the Mount. This is why I don't consider them to be Christians. What is known as "liberation theology" is merely following the Sermon on the Mount. Christianity does not provide any foundation for right-wing politics, yet some people are trying to twist it to do so. People like frankie graham are not Christians.
