What is Jerome's "Hebrew" Gospel?

[John Stephens]

The above quote is included in Bart Ehrman's book _The New Testament and other Early Christian Writings_ under the title "The Gospel of the Nazareans," which survives only in fragments.

Written in Aramaic, possibly near the end of the first century or at the beginning of the second, the Gospel of the Nazareans was popular among Jewish Christians (sometimes called "Nazoreans") living in and around Palestine. ... According to some of the church fathers, this Gospel was in fact nothing other than an Aramaic revision of Matthew's Gospel. ... Scholars debate, however, whether the church fathers were right in their assesment of the book: its author may simply have known traditions about Jesus similar to those also available to Matthew. The fragments of the Gospel that do survive, in any event, share with Matthew a concern for the Jewish Law and the question of whether the Jewish people are able to keep it.

Ehrman includes about two pages of fragments from Pseudo-Origen, Eusebius, Jerome, and "corrections" made by various scribes to several Greek manuscripts of Matthew.

Hope this helps!
