Synopsis: Since the time of Jerome, scholars have tried to explain why John the Baptist asks Jesus if he is "the one who is to come" (Matt 11:2-6; Luke 7:18-23) after he had apparently identified him as "the lamb of God" (John 1:29-34). The puzzling question is part of one of the longest fragments of traditional material in the New Testament dealing with the Baptist and Jesus. The present study critically examines the Lukan version of this double tradition normally attributed to Q, which includes John's question as well as Jesus' testimony about the Baptist (7:24-28) and his reproach of the religious leaders (7:29-35).
