Basil the Great
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.
Or, the Lord remained for forty days untempted, for the devil knew that He fasted, yet hungered not, and dared not therefore approach Him. Hence it follows: And he eat nothing in those days. He fasted indeed, to shew that He who would gird Himself for struggles against temptation must be temperate and sober.
