Pope Francis on Saturday named a new prefect for the Dicastery for the Doctrine of the Faith, replacing Cardinal Luis Ladaria Ferrer with the Argentine theologian Archbishop Víctor Manuel Fernández.While the pope’s decision to name Archbishop Fernández took many by surprise, the appointment itself was long overdue. Cardinal Ladaria turned 79 in April, and was closer to the mandatory age of exclusion for cardinals from a conclave (80) than to the nominal episcopal retirement age of 75.
