Analysis of information sources in references of the Wikipedia article "Gospel of Mark" in English language version.
Most critical scholars deny that Mark was the author or that he wrote on the basis of Peter's recollections
Though the author's identity is unknown, scholars find clues about its author in the Gospel itself. For example, its awkward style suggests that Greek was not the author's first language. Other details, such as the imprecise citation of Jewish scripture (1.2), the over-generalized portrait of Jewish practice (7.3–4), and problematic geographical details (5.1,13) suggest that the evangelist was a Hellenized Jew who lived outside of Palestine.
