In the same book the same St. Ambrose says again:1905 "Now if Peter fell, who said, Though all men shall be offended, yet will I never be offended,' who else shall rightly presume concerning himself? David, indeed, because he had said, In my prosperity I said, I shall never be moved,' confesses how injurious his confidence had proved to himself: Thou didst turn away Thy face,' he says, and I was troubled.'"1906 Pelagius ought to listen to the teaching of so eminent a man, and should follow his faith, since he has commended his teaching and faith. Let him listen humbly; let him follow with fidelity; let him indulge no longer in obstinate presumption, lest he perish. Why does Pelagius choose to be sunk in that sea whence Peter was rescued by the Rock?1907
