Q資料
Theissen and Merz argue the genre of a collection of sayings was one of the earliest forms in which material about Jesus was handed down. They assert that other collections of sayings, such as the Q source and the collection underlying Mark 4, were absorbed into larger narratives and no longer survive as independent documents, and that no later collections in this form survive.Marvin Meyer also asserted that the genre of a "sayings collection" is indicative of the 1st century, and that in particular the "use of parables without allegorical amplification" seems to antedate the canonical gospels.
