James is one of the most significant, yet generally overlooked, letters of the New Testament. Because Martin Luther, leader of the Protestant Reformation, disliked the book of James for its emphasis on good deeds, the book has come to be viewed in opposition to Paul's letters, which emphasize faith in God. To correct these and other misperceptions about James, Scripture scholar Luke Timothy Johnson embarks on a thorough history of the interpretation of this pivotal letter, which highlights the vast appreciation for James over the centuries. With respect to the question of who wrote the letter of James, Johnson boldly identifies the writer as none other than James, the brother of Jesus Christ. While modern skepticism casts doubt on this conclusion, early textual witnesses, as well as saints and scholars throughout the centuries, corroborate Johnson's position. A thorough examination of the original language texts and an explanation of the literary context of James helps illuminate the original meaning of the letter. In addition, Johnson offers the general reader insights into the letter's relevance for today.
