Abstract: The distinction between the initial citation and sequential variants put forward in Chapter Five also proves to be useful in the analysis of Augustine's Sermones ad populum and Enarrationes ad Psalmos. Eighty-three sermons can be identified as following the liturgical reading of the Gospel according to John, which makes them a potential source of primary citations. Many of these feature an Old Latin text-type, even some preached as late as 418; this appears to be a particular characteristic of sermons preached in Carthage. In later sermons, however, the influence of the Vulgate on Augustine's mental text displaces his customary Old Latin readings.
