Tim Enloe has posted more on “Romanitas” and the Papacy, specifically on the concept of the paterfamilias:
The word “pope” comes from the Latin papa, which of course, means “father.” To understand the cultural world of Romanitas, which deeply undergirds papal theory and assumptions about reality, we must understand about father is the concept of paterfamilias. This term can also mean “father,” but to unpack its implications it is better to say that it means “head of the house.”
