Matthew's Gospel is known for its long, flowing discourses. The speeches in Luke, by contrast, are shorter and scattered throughout his narrative. Some believe this difference is evidence against the so-called ‘Farrer hypothesis’ – the view that Luke used both Mark and Matthew as sources. One response, however, is that Luke wanted to bring his speech lengths into closer conformity with the literary standards of Greco-Roman bioi. An analysis of seventeen representative bioi suggests that Matthew's speeches were exceptionally long for medium-sized biographies such as his own. This fact provides a plausible literary motivation for Luke to abbreviate Matthew's discourses.
