Note 2 — Chapter I

The primary meaning of the word Catholic seems to refer to world-wide extension. St. Augustine teaches that it means "Universal" as opposed to particular, and says that "The Church is called Catholic because it is spread throughout the whole world". St. Cyril of Jerusalem says: "The Church is called Catholic because it extends throughout the whole world, from one end of the Earth to the other," and he adds, "because it teaches universally all the doctrines which men ought to know" ("Catechetical Lectures," xviii. 23).
