St. Augustine: "The authority of the Catholic Church"

“BUT should you meet with a person not yet believing the Gospel, how would you reply to him were he to say, I do not believe? For my part, I should not believe the Gospel except as moved by the authority of the Catholic Church.”

~St. Augustine of Hippo: Against the Epistle of Manichaeus Called Fundamental, Chap. 5.
