New Testament [SEP] Authors
The books of the New Testament were all or nearly all written by Jewish Christians—that is, Jewish disciples of Christ, who lived in the Roman Empire, and under Roman occupation. Luke, who wrote the Gospel of Luke and the Book of Acts, is frequently thought of as an exception; scholars are divided as to whether Luke was a Gentile or a Hellenistic Jew. A few scholars identify the author of the Gospel of Mark as probably a Gentile, and similarly for the Gospel of Matthew, though most assert Jewish-Christian authorship.
