The Gospel then has come to us, not merely to make us good subjects, good citizens, good members of society, but to make us members of the New Jerusalem, and "fellow-citizens with the saints and of the household of God." Certainly no one is a true Christian who is not a good subject and member of society; but neither is he a true Christian if he is nothing more than this. If he is not aiming at something beyond the power of the natural man, he is not really a Christian, or one of the elect.
--Blessed Cardinal John Henry Newman, “The Visible Church for the Sake of the Elect”, Parochial and Plain Sermons, Volume 4.
