This name Catholic sounds not of Marcion, nor of Apelles, nor of Montanus, nor does it take heretics as its authors. . . . . Christian is my name, but Catholic my surname. That names me, this describes me; by this I am approved; by that designated. And if at last we must give an account of the word Catholic, and express it, from the Greek, by a Latin interpretation, Catholic is "everywhere one", or, as the more learned think, obedience in all the commandments of God. . . . Therefore he who is a Catholic, the same is obedient to what is right. He who is obedient, the same is a Christian, and thus the Catholic is a Christian.
