DID YOU KNOW?
The answer
Material found only in Matthew, and material found only in Luke. The other two of the four sources are Mark and Q, the lost collection of sayings that Matthew and Luke are thought to have shared.
Why it’s interesting
Nobody knows what M and L were. They may have been written sources, stories passed on by word of mouth, or the writers' own work. The workers in the vineyard are M material, and the Good Samaritan is L (Matthew 20:1-16; Luke 10:29-37).
