The problem is what might be called episcopal overreach. Anything which falls within the sphere of faith and morals is the business of bishops. But many things—like physics, mathematics, monetary policy’s technical aspects, the science of the weather, World War I’s historical origins, the color I choose to paint a wall etc.—are not. . . .It is thus unclear why popes and bishops address these types of subjects in their capacity as authoritative teachers of the Catholic Faith.
