“You know what the Catholic Church is, and what that is cut off from the Vine; if there are any among you cautious, let them come; let them find life in the Root. Come, brethren, if you wish to be engrafted in the Vine: a grief it is when we see you lying thus cut off. Number the Bishops even from the very seat of Peter: and see every succession in that line of Fathers: that is the Rock against which the proud Gates of Hell prevail not.”

St. Augustine to the schismatic Donatists
