This fourth volume in the series Documenta Q is concerned with the reconstruction of the Q text behind Luke 12:8-9 par. Matt 10:32-33 ("Confessing or Denying"), Luke 12:10 par. Matt 12:32 ("Speaking against the Holy Spirit"), Luke 12:11-12 par. Matt 10:19 ("Hearings before Synagogues"), and Matt 10:23 ("Fleeing among the Towns of Israel" which, it was decided, does not belong to Q). The International Q Project's presentation of the critical text of Q 12:8-12, together with the exhaustive history of research on which it is based, will considerably enhance research in the Sayings Gospel Q, the historical Jesus, and New Testament christology. The databases and evaluations are an expanded and revised version of those presented and discussed at the meetings of the International Q Project in New Orleans 1990 (Q 12:10), San Francisco 1992 (Matt 10:23), Washington 1993 (Q 12:8-9), and Rattenbach/Niederbayern 1994 (Q 12:11-12). (Lucan chapter and verse numeration is used as a convenience and a mere convention.) Just prior to the bibliography at the conclusion of the volume the resultant critical text of Q 12:8-12 is printed. Then this Greek text is followed by English, German and French translations.
