Unless curbed by the fear of God that accompanies the practice of the virtues, spiritual knowledge leads to vanity; for it encourages the person puffed up by it to regard as his own what has merely been lent to him, and to use his borrowed intelligence to win praise for himself.

They are the Church who are a people united to the Priest, and the flock which adheres to its Pastor. From this you ought to know that the Bishop is in the Church, and the Church is in the Bishop; and if anyone is not with the Bishop, that he is not in the Church, and that those who flatter themselves and creep in, and commune secretly with some, do so in vain, not having peace with God's Priests; while the Church, which is universal and one, is not cut nor divided, but is indeed connected and bound together by the bond of Priests who unite with one another.
