The Form of ‘Q’ known to Matthew

It is usually assumed that Matthew did not know Luke, nor Luke Matthew. The non-Marcan (‘Q’-) materials common to Matthew and Luke, then, ultimately go back to a common source or sources, oral or written, much of which anyway had reached a fixed Greek form. Attempts have been made to split up the source of the Q-materials into two documents, into one-sheet ‘tracts’, and into individual floating sayings.
