The teachings ascribed to Jesus in John, then, are spurious; while those ascribed to him in Matthew, Mark and Luke are of doubtful authenticity. If any of the teachings of Jesus have been preserved they exist in the first three Gospels, but the unauthentic character of the Gospels themselves, renders it impossible to ascribe to him with certainty a single teaching.
CHAPTER VI.
The Crucifixion of Christ.
268
When did Jesus first foretell his passion?
Synoptics: Not until late in his ministry ([Matt. xvi, 21]; [Mark viii, 31]; [Luke ix, 21–27]).
According to John ([ii, 19–22]) he referred to it at the beginning of his ministry.
