2 Among His other acts, lo, the Virgin's Son comes to the marriage; who being with the Father instituted marriage. As the first woman, by whom came sin, was made of a man without a woman; so the Man by whom sin was done away, was made of a woman without a man. By the first we fell, by the other we rise. And what did He at this marriage? Of water He made wine. What greater sign of power? He who had power to do such things, vouchsafed to be in need. He who made of water wine could also have of stones made bread.
The power was the same; but then the devil tempted Him, therefore Christ did it not. For you know that when the Lord Christ was tempted, the devil suggested this to Him. For He was an hungred, since this too He vouchsafed to be, since this too made part of His Humiliation. The Bread was hungry, as the Way fainted, as saving Health was wounded, as the Life died. When then He was an hungred as you know, the tempter said to Him, “If Thou be the Son of God, command that these stones be made bread.” And He made answer to the tempter, teaching you to answer the tempter.
For to this end does the general fight, that the soldiers may learn. What answer did He make? “Man does not live by bread alone, but by every word of God.” And He did not make bread of the stones, who of course could as easily have done it, as He made of water wine. For it is an exercise of the same power to make bread of stone; but He did it not, that He might despise the tempter's will. For no otherwise is the tempter overcome, but by being despised. And when He had overcome the devil's temptation, “Angels came and ministered to Him.” He then who had so great power, why did He not do the one, and do the other?
Read, yea, recollect what you have just heard, when He did this, when, that is, He made of the water wine; what did the Evangelist add? “And His disciples believed on Him.” Would the devil on the other occasion have believed on Him?
