One thing about Fundamentalists and Evangelicals that corresponds to Progressive Christians is that they are serious about their religion.
They genuinely want to establish God's reign on Earth.
Unfortunately they are mistaken about what that reign entails.
They mistake God's Love for morality.
And His goodness for righteousness.
And they try to force their errors onto others.
At the root of this is fear.
Fear of God's punishment.
So Jesus was right about them:
"'Why do you see the speck in your neighbor's eye, but do not notice the log in your own eye?.....You hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your neighbor's eye.'" Matthew 7:3-5 (NRSV)
