Epiphanius writes of the ancient Nazarenes:

But these sectarians… did not call themselves Christians–but “Nazarenes,”… However they are simply complete Jews. They use not only the New Testament but the Old Testament as well, as the Jews do…
(Panarion 29)

Like the ancient Nazarenes, modern Nazarne Jews recognize the Tanak (commonly called the “Old Testament”) and the Ketuvim Netzarim (commonly called the “New Testament”) as Scripture.

About the Tanak

For special information on the Letter to the Hebrews read:

In Defense of the Book of Hebrews

However our primary texts for the books of the Ketuvim Netzarim are those of the ancient Hebrew and Aramaic manuscripts of these books, rather than their Greek translations. For more on the Hebrew and Aramaic Origin of these books see:

The Hebrew and Aramaic Origin of the New Testament

Many Nazarenes also accept certain additional books as Scripture:

The Gospel according to the Hebrews

The Apocrypha

The Book of Enoch

The Book of Jasher
