The Epistle of Barnabas (Ancient Greek: Βαρναβᾶ Ἐπιστολή) is an early Christian Greek epistle written between AD 70 and AD 135. The complete text is preserved in the 4th-century Codex Sinaiticus, where it appears at the end of the New Testament, following the Book of Revelation and before the Shepherd of Hermas. For several centuries, it was one of the "antilegomena" ("disputed") writings that some Christians looked at as sacred scripture, while others excluded them. Eusebius of Caesarea classified it with excluded texts. It is mentioned in a perhaps third-century list in the sixth-century Codex Claromontanus and in the later Stichometry of Nicephorus appended to the ninth-century Chronography of Nikephoros I of Constantinople. Some early Fathers of the Church ascribed it to the Barnabas mentioned in the Acts of the Apostles, but it is now generally attributed to an otherwise unknown early Christian teacher (though some scholars do defend the traditional attribution). It is distinct from the Gospel of Barnabas.
The central message of the Epistle of Barnabas is that the writings comprising the Hebrew Bible—what would become the Old Testament of the Christian Bible—were, from even their times of authorship, written for use by Christians rather than the Israelites and, by extension, the Jews. According to the epistle, the Jews had misinterpreted their own law (i.e., halakha) by applying it literally; the true meaning was to be found in its symbolic prophecies foreshadowing the coming of Jesus of Nazareth, whom Christians believe to be the messiah. Furthermore, the author posits that the Jews broke their covenant from the very beginning and were misled by an evil angel. After explaining its Christian interpretations of the Jewish scriptures, the epistle concludes by discussing the "Two Ways", also seen in the Didache: a "Way of Light" and a "Way of Darkness".
