Putting on Christ aims to situate Augustine’s early soteriology and sacramental theology within the context of his personal history and intellectual development. Beginning with an extended analysis of the theology of salvation and sacramental efficacy contained within Augustine’s Confessions (ca. 400), the study then traces the maturation of his views on these matters, beginning with his earliest extant works, the Cassicacum dialogues (ca. 386). The journey entails treating Augustine’s earliest discussions of Christ’s person and his saving work, as well as the believer’s subjective experience of conversion and salvation. As Augustine’s corpus shifts from philosophical dialogues to explicitly apologetic and scriptural-exegetical works, so too does his soteriological lexicon expand to include concepts and terms that will later become his stock-in-trade, such as the virtue of humilitas. And as his roles in the North African Church come to include participation in the presbyterate and the episcopacy, so too does his engagement expand to a wider set of polemical contexts, both anti-Manichaean and anti-Donatist. Putting on Christ tracks these and many other aspects of Augustine’s maturing thought, showing where lines of both continuity and development lie and aiming to uncover their reasons. In doing so, it reveals Augustine to be a thinker and a teacher who continued to hone his understanding of salvation, the very heartbeat of Christian life and thought, as well as its relation to various other aspects of the Christian theological worldview, from Christology and anthropology to sacramental theology and ecclesiology.
