“The Nazarenes do not differ in any essential thing from them [meaning the Orthodox Jews], since they practice the customs and doctrines prescribed by Jewish Law; except that they believe in Christ…. “They believe in the resurrection of the dead, and that the universe was created by God. They preach that God is One, and that Jesus Christ is his Son....
“They are very learned in the Hebrew language.
“They read the Law [meaning the Law of Moses]….
“Therefore they differ…from the TRUE Christians because they fulfill until now ‘Jewish’ rites as the circumcision, Sabbath, and others.”
[The Church Father Epiphanius in his doctrinal book, “Against Heresies,” Panarion 29, 7, Page 41, 402]
