This paper uses Sørensen's cognitive theory of magic, based on different cognitive mechanisms, to analyze two types of early Christian ritual meal. In the first section, it is demonstrated that this cognitive approach enables us to identify and classify some aspects of this ritual that recent socio-functionalistic and context-oriented scholarship has ignored despite their relative importance. From this perspective, the second section argues that conceptual blending of Jesus with bread and wine in the institution narrative has a natural tendency to evolve in transformative magical action and that this form is more attractive to cultural transition than the form of ritual prescribed in Didache. Finally, while using the cultural epidemiological perspective, the paper will model the process of spreading and authorization of the institution narrative in the development of early Christianity.
