Upon reading Strobel's book, he has a section written about "Q". Here is a section:
"In addition to the four gospels, scholars often refer to what they call Q, which stands for the German word Quelle , or "source". Because of similarities in language and context, it has traditionally been assumed that Matthew and Luke drew upon Mark's earlier gospel in writing their own. In addition, scholars have said that Matthew and Luke also incorporated some material from this mysterious Q, material that is absent from Mark."
yes you have to do what you believe/I like to take into account the beliefs of founding fathers. so often use them to reinforce my search. also, just want to clarify; the Q Source IS only the Sayings of Jesus/similar to what Thomas Jefferson pointed out. It's strictly verses from the Bible, so not sure some of the above in your reply. they didn't rewrite any verse; just noticed that many are common between Matthew and Luke.
