50.—Ambrose Teaches that All Men Need God’s Help.
In the same book the same St. Ambrose says again:121 Book x. c. 89. “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.’”122 Ps. xxx. 7. 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?123 It is impossible to preserve the paronomasia of the original, which plays on the meaning of the names Pelagius (pelago, sea) and Petrus (petra, rock).
50. Item in eodem libro idem sanctus Ambrosius: «Nam si Petrus,» inquit (Lib. 10, n. 91, ad Luc. XXII), «lapsus est, qui dixit, Etsi alii scandalizati fuerint, ego non scandalizabor (Matth. XXVI, 33); quis alius jure de se praesumat? Denique David quia dixerat, Ego dixi in mea abundantia, Non movebor in aeternum; suam sibi jactantiam obfuisse profitetur, dicens, Avertisti 0383 faciem tuam, et factus sum conturbatus» (Psal. XXIX, 7, 8). Audiat iste tantum virum docentem, imitetur credentem, cujus doctrinam fidemque laudavit. Audiat humiliter, imitetur fideliter: non de se pertinaciter praesumat, ne pereat. Quid in eo pelago vult mergi Pelagius, unde per petram liberatus est Petrus?
