This book investigates the narrative function of the Old Testament characters in the Gospel of John. The intriguing thesis is that the Hebrew characters in John's narrative uniformly function as a witness for the messianic identity of Jesus. The Jewish scriptural traditions (Hebrew and intertestamental ones) are compared to shed light on John's indebtedness for its formation of his Christology. A compelling argument ensues that informs our understanding, not only of the Gospel itself, but also of Jesus Christ revealed in the Gospel. 'Ahn's study rewards the reader with a rigorous review of vast fields of scholarship as well as deep discussions on single Johannine motifs. The Christocentric lens does not only help to understand the Gospel of John but offers biblical theological implications as well.' Lars Kierspel, Associate Professor of Biblical Studies, Shiloh University, USA 'Dr. Ahn's thorough and careful study of the function of Scriptural figures as a witness to Christ in the Fourth Gospel represents a solid contribution, from which many will benefit. All serious interpreters of the Johannine witness will want to refer to this work.' Mark A. Seifrid, Ernest and Mildred Hogan Professor of New Testament, Southern Baptist Theological Seminary, USA 'This is a masterful survey of the English, German, and French literature on the subject, that should be required reading for any serious student of the Christology of the Fourth Gospel. Ahn is to be thanked for making German and French discussions on the Christology of John available to students lacking access to these languages.' Robert H. Stein, Senior Professor of New Testament Interpretation at The Southern Baptist Theological Seminary, USA 'This work stands out if for no other reason that its author has taken the trouble to engage as comprehensively as possible with contemporary research with fairness and no short-cuts. Beyond that, it provides a careful evaluation of the witness function of Old Testament figures for John's Christology considered in the context of Jewish literature of the period. A rich resource, replete with useful appendices, and a rewarding read for all who engage Johannine studies. I certainly want it on my shelf.' William Loader, Murdoch University, Western Australia.
