This book investigates Martin Luther King, Jr.’s religious development from a precocious “preacher’s kid” in segregated Atlanta to the most influential American preacher and orator of the twentieth century. To give an intimate portrait, the book draws almost exclusively on King’s unpublished sermons and speeches, as well as tape recordings, personal interviews, and even police surveillance reports. By returning to the raw sources, it recaptures King’s real preaching voice and, consequently, something of the real King himself. The book shows how as the son, grandson, and great-grandson of preachers, King early on absorbed the poetic cadences, traditions, and power of the pulpit, as profoundly influenced by his fellow African-American preachers as he was by Gandhi and the classical philosophers. The book also reveals a later phase of King’s development: the prophetic rage with which he condemned American religious and political hypocrisy. During the last three years of his life, the book shows, King accused his country of genocide, warned of long hot summers in the ghettos, and called for a radical redistribution of wealth.
