M.A. / This study investigates the connection between the biblical references to the Gospels in Actae Thoma, or the Apocryphal Acts of Judas Thomas, and the text of the Vetus Syria. The main objective is to verify whether the author of Actae Thoma was dependent on the Vetus Syria which was one of the largest and oldest Syriac text families containing the separate Gospels. An independent study in this regard has not yet been undertaken. Both Klijn and Burkitt touched on the biblical references in Actae Thoma but they did not attempt to investigate the references as the sole object of their research. The present study attempts to investigate all the biblical references in order to verify whether the author of Actae Thoma was indeed dependent on the Vetus Syria. The function of these references within the new context of Actae Thoma is also investigated. The value of the study lies in its contribution to our understanding of the Syriac textual history and of the function of these references. It seems that they were used to propagate the ideals of asceticism, to enhance the figure of the Apostle and bring the reader under the impression that he finds himself in a Biblical milieu. A basis for further study is also provided.
