The fifth volume in the series Documenta Q is concerned with the reconstruction of the Q text behind Luke 22:28, 30 par. Matt 19:28. The International Q Project's presentation of the critical text of Q 22:28, 30, 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 christology. Further, nowhere else in the Synoptic tradition is the claim of the Jesus movement regarding Israel stated more clearly than in Q 22:28, 30. The database and evaluations are an expanded and revised version of those presented and discussed at the meeting of the International Q Project in Chigaco 1994. Just prior to the bibliography at the conclusion of the volume the resultant critical text of Q 22:28, 30 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.)
