Catena Aurea · Lukasevangelium 4
And Jesus being full of the Holy Ghost returned from Jordan, and was led by the Spirit into the wilderness, Being forty days tempted of the devil. And in those days he did eat nothing: and when they were ended, he afterward hungered. And the devil said unto him, If thou be the Son of God, command this stone that it be made bread. And Jesus answered him, saying, It is written, That man shall not live by bread alone, but by every word of God.
You see then what kind of arms He uses to defend man against the assaults of spiritual wickedness, and the allurements of the appetite. He does not exert His power as God, (for how had that profited me,) but as man He summons to Himself a common aid, that while intent upon the food of divine reading He may neglect the hunger of the body, and gain the nourishment of the word. For he who seeks after the word cannot feel the want of earthly bread; for divine things doubtless make up for the loss of human. At the same time by saying, Man lives not by bread alone, He shews that man was tempted, that is, our flesh which He assumed, not His own divinity.
