Recent work has improved the understanding of social structures in theological
discourse, but ambiguity persists with respect to structures of sin. Here, a revised
definition of structural sin reconnects this concept with its theological roots, adding
clarity to the nature of structural sin and strengthening the moral weight of the
term. Parallels with fMRI research in the field of moral psychology then refine the
existing account of the operation of structural sin. Together, these insights aid in the
identification of structures of sin and improve efforts to combat their influence.
