Martin Luther King uses an appeal of ethos which created credibility, an essential part of an argument because it gives the readers a belief that the author knows what he is talking about In King’s letter he gives a bible reference of Shadrach, Meshach, and Abednego refusing to obey the laws of Nebuchadnezzar because there was a higher moral law that was at stake(King 384). He also states that non violent protest was practiced very well by the early Christians who were willing to “face hungry lions and the excruciating pain of chopping blocks rather than submit to certain unjust laws of the Roman Empire”(King 384) King also makes a wise decision to choose this verse because it conveys that civil disobedience was practiced in the early days by fellow Christian brothers. This creates credibility with the Clergymen because as religious leaders it is essential to know the words written in the Bible. He also further applies his knowledge of the bible and talks about how people are telling him to stop the non-violent protest and he implies that “Shallow understanding from people of good will is more frustrating than absolute misunderstanding from the people of ill will.
