The early part of St.Matthew is broken up by the intrusion of the so-called Sermon on the Mount, but all this time St.Mark is in approximate agreement with St.
Luke.

For a short space the three Gospels go together.

Then comes a second break, where Luke introduces his version of the Sermon on the Mount.

Then the three rejoin and proceed together, Matthew being thrown out by the way in which he has collected the parables into a single chapter, and Luke later by the place which he has assigned to the incident at Nazareth.

After this Matthew and Mark proceed side by side, Luke dropping out of the ranks.
