This book arises out of contemporary questions regarding the nature and formation of the church amidst an economically divided society. Looking to Augustine of Hippo for guidance, Jonathan D. Ryan argues that the movement from private self-interest toward common love of God and neighbor is fundamental to the church’s formation and identity amidst contemporary contexts of economic inequality. Ryan demonstrates the centrality of this theme in Augustine’s Sermons and his monastic instruction (principally the Rule), illustrating how it shapes his pastoral guidance on matters pertinent to economic division, including use of material resources, and attitudes toward rich and poor. By reading Augustine’s Sermons alongside his monastic instruction, this volume allows for a closer understanding of how Augustine’s vision of a common life is reflected in his pastoral guidance to the wider congregation. The book’s concluding reflections consider what the church in our time might learn from these aspects of Augustine’s teaching regarding the formation of a common life, as members are drawn together in love of God and neighbour.
