This work examines whether the theological method currently known as inculturation is found in the Supper Narratives of the New Testament. A methodology is set up in which texts are examined against the backdrop of Graeco-Roman, Judaic and early Christian cultures. This leads to the conclusion that the New Testament writers used a methodology which can be identified as inculturation including, e.g., Judaic practice as a corrective to Graeco-Roman sacramental custom.
