Synoptic Gospels and the nature of Q
The Q document must have been composed before Matthew and Luke; some scholars even suggest that Q predated Mark. A date for the final Q document is often placed in the 40s or 50s of the 1st century, with some arguing its so-called sapiential layer (1Q, containing six wisdom speeches) was written as early as the 30s.
