The ninth volume in the series Documenta Q is concerned with the reconstruction of the Q text behind Luke 6:37-42 par. Matt 7:1-5; 10:24-25a; 15:14. The database and evaluations are expanded and revised versions of those presented and discussed at the meetings of the International Q Project in New Orleans 1990, in Claremont, CA 1991 and Toronto 1993. Just prior to the bibliography at the conclusion of the volume the resultant critical text of Q 6:37-42 is printed. This Greek text is followed by English, German and French translations (Lucan chapter and verse numeration is used as a convenience and a mere convention). The International Q Project's presentation of the critical text of Q 6:37-42, together with the exhaustive history of research on which it is based, will enhance considerably research in the Sayings Gospel Q, the historical Jesus, and New Testament theology.
