Past scholarly literature has interpreted the orientation of the teaching of the Paraclete in the Fourth Gospel as either retrospective or prospective. First, I will argue that it is prospective, but that this does not imply that the Paraclete teaches things that have not yet been taught by Jesus. The Gospel text challenges us to conceive the teaching of the Paraclete as prospective, but also as repeating Jesus’ teaching. A synthesis of the retrospective and prospective interpretation is thus required. Second, I will argue that this paradoxical synthesis can be obtained on the basis of Kierkegaard's category of repetition.

Biblical proof-texts for the prophethood of Muḥammad play a prominent role in early Muslim interest in the Bible. This study re-examines the earliest known attempt by Muslims to find such a biblical proof-text in the New Testament – the Arabic version of Jesus's sermon on the “advocate/comforter” (Gk. paráklētos) in John 15: 23–16 found in Ibn Isḥāq's Kitāb al-Maghāzī. Key to understanding Ibn Isḥāq's adaptation of the Johannine text, this study argues, is the Christian Palestinian Aramaic Gospel behind it as well as the climate of Late Antique apocalypticism and messianism out of which Ibn Isḥāq's distinctively Islamic version emerged. This study concludes with an interpretation of Quran 61: 6, which appears to claim that Jesus prophesied a future prophet named Aḥmad.
