James & Jude, New Cambridge Bible Commentary

The letters of James and Jude are famously "under-interpreted," and this is the first commentary to focus exclusively on the two letters written by the "brothers of the Lord." The commentary interprets the letters of James and Jude as having been written early in the life of the Church and maintains that the letter of James may be one of the oldest Christian writings as well as an early witness to the teachings of Jesus.
