This book argues that Paul's seminal thesis on human moral formation in Romans 12:1–2 can be best understood when it is interpreted through the lens of a philosophical and theological anthropology that merges the views of Thomas Aquinas and James K. A. Smith.

This view claims that Paul's admonition to renew the mind in Romans 12:2 is best accomplished when human reason is understood to be the operation of the unified human soul that integrates the intellectual, sensitive, and appetitive powers within a specific socio-cultural context.
