In this chapter, I contextualize the discourse of orality as the privileged medium of revelation through three corpora; rabbinic idea of Oral Torah, the Manichaean claim that the Kephalaia contain Mani’s Oral Revelation not found in his Written Revelations, and the Pseudo-Clementine’s argument that only Orality (not vision) can guarantee prophetic truth. I ultimately argue that all three drew from a common fund of discursive tools to thematize orality as a privileged site of revelation. After a summary of contemporary discussions on rabbinic Oral Torah, I show how the Kephalaia itself emerged from an “Oral Performative” contexts that was largely independent of textual exegesis of Mani’s books. I argue that, like the rabbis, the Manichaeans privileged the orality because it allowed them to claim that they were simply continuing the revelation that Mani had begun. I then turn to the Ps.-Clementine Homilies and show it thematizes orality in ways that are surprisingly congruent with both the rabbis and the Manichaeans.
