Be sure to check out Augustine and Ethics, a newly released volume in the Augustine in Conversation: Tradition and Innovation Series by Lexington Books. Edited by Sean Hannan and Kim Paffenroth, this volume:

“includes reflections on virtue and vice, love and sin, and the political outcomes to which certain ethical stances tend to give rise. For Augustine himself, ethics was never merely theoretical. Ethical concerns are concrete; and ethical solutions should be practical. Accordingly, this volume gives Augustinian ethical arguments realization by connecting them to modern anxieties about ministry, health care, diet, and incarceration.”
