In the “Letter from Birmingham Jail” Martin Luther King Jr is addressing eight clergymen those who is criticizing his actions of someone who is trying to disrupt the established order and peace of the society. In the concerned letter, Luther is starting with “fellow clergymen” to show that he, in fact, shares exactly same Christian believes and values as his white clergymen brothers. Throughout the letter Martin Luther King makes sure to appeal to Christian principles making references to biblical figures. He also addresses white moderates, Jewish people and, indirectly, the rest of the population. Mr. King is using a combination of pathos, ethos, logos to persuade his audience. The most effective and frequently used in the letter is ethos.
