Chapter 50.—Ambrose Teaches that All Men Need God&#8217;s Help.

In the same book the same St. Ambrose says again: “Now if Peter fell, who said, &#8216;Though all men shall be offended, yet will I never be offended,&#8217; who else shall rightly presume concerning himself? David, indeed, because he had said, &#8216;In my prosperity I said, I shall never be moved,&#8217; confesses how injurious his confidence had proved to himself: &#8216;Thou didst turn away Thy face,&#8217; he says, &#8216;and I was troubled.&#8217;” 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?
