This letter is purported to have been written by James, the brother of the Lord and head of the Church at Jerusalem, to Jewish Christians in the diaspora. He assumes knowledge of the Gospel on the part of his readers and is concerned to remind them how Christians ought to live. In this letter, James makes the famous assertion that faith by itself, if it has no works, is dead (2:15). In addition, he speaks eloquently concerning the use of the tongue for good and evil (3:1-12), as well as prayer for the sick (5:13-16). This text is used by the Orthodox Church concerning the Mystery of Holy Unction or the Anointing of the Sick.
