The authors of the gospels, like all writers in all time periods, either reference information they have at hand – including things they’ve heard or read – or they make things up. . . For reference material, the author of Mark relied not on Jesus himself or any writings from him. . . . His sole source(was): oral traditions passed along by word-of-mouth for four decades.
