Nazarene, in the New Testament, a title applied to Jesus and, later, to those who followed his teachings (Acts 24:5). In the Greek text there appear two forms of the word: the simple form, Nazarēnos, meaning “of Nazareth,” and the peculiar form, Nazōraios. Before its association with the locality, this latter term may have referred to a Jewish sect of “observants,” or “devotees,” and was later transferred to the Christians.
The term Nazarene is also applied to a Syrian Judeo-Christian sect of the 4th century ad. Although they accepted the divinity of Christ and his supernatural birth, the Nazarenes also maintained strict observance of Jewish laws and customs, a practice that had been dropped by the majority of Jewish Christians. They used a version of the Gospel in Aramaic called the Gospel According to the Hebrews, or the Gospel of the Nazarenes. Their relation to the Judeo-Christian sect of the Ebionites remains uncertain.
Arabs and Jews today employ the word Nazarene as a general designation for those of the Christian faith.
