Do Christians disagree with Mark's Gospel?

A:

Most Christians believe that the entire Bible is true, including Mark's Gospel. Since Mark is now known to have been the earliest New Testament gospel and that the other gospels were substantially based on Mark, either directly (Matthew and Luke) or indirectly (John), to disagree with Mark's Gospel on important issues would probably be to disagree with the gospels as a whole, which few Christians would do. Of course, there are minor errors in Mark that the subsequent evangelists recognised and corrected, but these are not substantive.
