"[J. M.] Robertson is prepared to concede the possibility of an historical Jesus perhaps more than one having contributed something to the Gospel story. "A teacher or teachers named Jesus, or several differently named teachers called Messiahs" (of whom many are on record) may have uttered some of the sayings in the Gospels. (J. M. Robertson, Christianity and Mythology, revised edition, p. 125) [...] What the myth theory denies is that Christianity can be traced to a personal founder who taught as reported in the Gospels and was put to death in the circumstances there recorded."
