The new head of the Dicastery for the Doctrine of the Faith is an Argentine archbishop who wrote a book advising couples to kiss during sexual intercourse if they wanted to stop their relationships from growing cold.

Pope Francis announced on Saturday that Archbishop Víctor Manuel Fernández, 60, his longtime personal theologian and ghostwriter, is the prefect of the Vatican department that maintains orthodoxy in Church teaching and doctrine.

The Archbishop of La Plata succeeds Cardinal Luis Ladaria Ferrer, SJ, 79, who has been prefect of the dicastery since 2017, and will inevitably be made a cardinal.
