30. To show indeed how plainly we must understand the expression “alone” of the Son (although we may never believe that He did anything without the knowledge of the Father), we have here also another passage, where it is written: “Which alone spreadeth out the heavens, and walketh as it were on a pavement over the sea.” Job ix. 8. For the Gospel of the Lord has taught us that it was not the Father but the Son that walked upon the sea, when Peter asked Him, saying, “Lord, bid me come unto Thee.” S. Matt. xiv. 28. But even prophecy itself gives proof of this. For holy Job prophesied of the coming of the Lord; of Whom he said in truth that He would vanquish the great Leviathan, Job xli. 8. and it was done. For that dread Leviathan that is, the devil, He smote, and struck down, and laid low in the last times by the adorable Passion of His own Body. Isa. xxvii. 1.
