The article provides an overview of the three distinct approaches to the exegesis of theophanies documented in the surviving works of Justin Martyr. It argues, contrary to previous scholarship on Justin Martyr, and in agreement with Larry Hurtado, that the argument from theophanies precedes its use by Justin, and suggests that the Dialogue and the Apologies may offer a glimpse into the process by which the exegetical disagreement over theophanies contributed to the crystallization of distinct “Jewish” and “Christian” social identities.
