This is the first commentary to focus exclusively on the two letters written by the ‘brothers of the Lord’, James and Jude. Each letter is discussed on its own merits, and interpreted as having been written early in the life of the Church - it is posited that the letter of James may be one of the oldest Christian writings as well as an early witness to the teachings of Jesus. Particular attention is devoted to understanding the social worlds of James and Jude and to interpreting the significance of their message for our day. Of special interest is the focus on the ‘ideological texture’ of James, in particular on James’ working out of the ethical implications of the teachings of Jesus on poverty and wealth.
