The Letter of James frequently uses certain terms such as “brother, pray, faith, sin, judgment.” It is the book of the New Testament that most closely resembles Old Testament wisdom literature, and its contents are very similar to those of the “Sermon on the Mount,” as the author, although only mentioning the Lord Jesus Christ twice (James 1:1; 2:1), speaks like Him.
The result is an eminently practical text, in which doctrinal teaching, as it is normally conceived, is absent. Nothing is said about the person and life of the Lord Jesus, His incarnation and redemption, His death and resurrection, while elements of eschatology and ecclesiology are present. Theological and exhortative concepts are not distinguished, as is usually the case in Paul's writings, because James intertwines and overlaps faith and works, theology and practice, doctrine and ethics, assuming that practice cannot be separated from dogma
