This article uses a little‐known sermon by Victricius, bishop of Rouen, as an approach to the fourth‐century debate on the translation of relics. In the last third of the fourth century, the cult of martyrs and their relics was promoted by Damasus of Rome, Paulinus of Nola and Ambrose of Milan, but remained controversial in the western churches. Roman law forbade the disturbance of dead bodies, especially where magic was suspected. Christians as well as non‐Christians were repelled by the veneration of bone, bloodstains and dust, and by the extreme asceticism that was often associated with relic‐cult. The sermon Victricius preached, welcoming to Rouen a gift of relics from Ambrose, is here interpreted as an attempt at cultural translation. Victricius deploys a late‐antique education in rhetoric and philosophy to make relic‐cult and asceticism acceptable. Like many others, he uses the adventus, the ceremonial reception of a visiting emperor or his deputy by local aristocracy and officials, as an analogy for the reception of relics by ascetics and clergy. Exceptionally, he equates corporeal relics with the presence of God; but his unique theology of relics was lost to view.
