With my fiancee, Clara Jace, I’ve recently written a paper that puts a new spin on agency theory.
The Roman Catholic doctrine of in persona Christi Capitis guarantees the validity of a sacrament, regardless of the personal holiness of the clergy administrating it. This suggests that the adoption of in persona Christi Capitis ought to have been accompanied by more stringent screening of candidates for the priesthood. Otherwise, the doctrine opens the door to opportunism. And that’s in fact what we find.
