Editing Two-source hypothesis (section)

=== The existence of Q ===
{{Main|Q source}}
The 2SH explains the double tradition by postulating the existence of a lost "sayings of Jesus" document known as Q, from the German ''Quelle'', "source". It is this, rather than Marcan priority, which forms the distinctive feature of the 2SH as against rival theories. The existence of Q follows from the conclusion that, as Luke and Matthew are independent of Mark in the double tradition, the connection between them must be explained by their joint but independent use of a missing source or sources. (That they used Q independently of each other follows from the fact that they frequently differ quite widely in their use of this source).<ref name="synop"/>
