But though I was initially disappointed at being categorized as an extremist, as I continued to think about the matter I gradually gained a measure of satisfaction from the label. Was not Jesus an extremist for love: "Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you." Was not Amos an extremist for justice: "Let justice roll down like waters and righteousness like an ever-flowing stream." Was not Paul an extremist for the Christian gospel: "I bear in my body the marks of the Lord Jesus." Was not Martin Luther an extremist: "Here I stand; I cannot do otherwise, so help me God." And John Bunyan: "I will stay in jail to the end of my days before I make a butchery of my conscience." And Abraham Lincoln: "This nation cannot survive half slave and half free." And Thomas Jefferson: "We hold these truths to be self-evident, that an men are created equal ..." So the question is not whether we will be extremists, but what kind of extremists we viii be. Will we be extremists for hate or for love? Will we be extremist for the preservation of injustice or for the extension of justice?
The whole letter is amazing. You should read it if you never have. It's long-eleven pages. It was begun on margins of newspaper and scraps of toilet paper.
