In 1963, Birmingham police jailed Martin Luther King for leading a nonviolent protest against the city's segregation. Several Alabama clergymen expressed disagreement with King's tactics. From his cell, he answered their objections.
You express a great deal of anxiety over our willingness to break laws. This is certainly a legitimate concern. Since we so diligently urge people to obey the Supreme Court's decision of 1954 outlawing segregation in the public schools, it is rather strange and paradoxical to find us consciously breaking laws. One may well ask: "How can you advocate breaking some laws and obeying others?" The answer is found in the fact that there are two types of laws: There are just laws and there are unjust laws. I would be the first to advocate obeying just laws. One has not only a legal but moral responsibility to obey just laws. Conversely, one has a moral responsibility to disobey unjust laws. I would agree with Saint Augustine that "An unjust law is no law at all."
Now what is the difference between the two? How does one determine when a law is just or unjust? A just law is a man-made code that squares with the moral law or the law of God. An unjust law is a code that is out of harmony with the moral law. To put it in the terms of Saint Thomas Aquinas, an unjust law is a human law that is not rooted in eternal and natural law. Any law that uplifts human personality is just. Any law that degrades human personality is unjust. All segregation statutes are unjust because segregation distorts the soul and damages the personality. It gives the segregator a false sense of superiority and the segregated a false sense of inferiority. To use the words of Martin Buber, the great Jewish philosopher, segregation substitutes an "I-it" relationship for an "I-thou" relationship, and ends up relegating persons to the status of things. So segregation is not only politically, economically, and sociologically unsound, but it is morally wrong and sinful. Paul Tillich has said that sin is separation. Isn't segregation an existential expression of man's tragic separation, an expression of his awful estrangement, his terrible sinfulness? So I can urge men to obey the1954 decision of the Supreme Court because it is morally right, and I can urge them to disobey segregation ordinances because they are morally wrong.
