Summary:

The Gospel of Barnabas is a book depicting the life of Jesus, and claiming to be by Jesus' disciple Barnabas, who in this work is one of the twelve apostles. Two manuscripts are known to have existed, both dated to the late 16th century and written respectively in Italian and in Spanish—although the Spanish manuscript is now lost, its text surviving only in a partial 18th-century transcript. Barnabas is about the same length as the four Canonical gospels put together, with the bulk being devoted to an account of Jesus' ministry, much of it harmonized from accounts also found in the canonical gospels. In some key respects, it conforms to the Islamic interpretation of Christian origins and contradicts the New Testament teachings of Christianity.
