Jesus answered them,
I told you, and you believed not: the works that I do in my Father's name, they bear witness of me.
All Commentaries on John 10:25 Go To John 10
Cyril of Alexandria
AD 444
Even Christ therefore considered it superfluous to say the same things over again to those who had often heard them and had not been persuaded by them. For every one's nature ought to be estimated from the quality of his works, and we ought by no means to look [solely] at his words. And He says of Himself that He accomplishes His works in His Father's Name, not enjoying the use of power from above in the manner of an ordinary saint, nor accusing Himself of want of power, being God of God, Consubstantial with the Father, the Power of the Father; but as ascribing to the Divine Glory the Power of His performances, He says that He does His works in His Father's Name. Yet He also gives the honour to the Father, lest He might give the Jews a pretext for attacking Him. Moreover He also thought it fitting not to overpass the limit of the form of a servant, although He was God and Lord. And by saying that in His Father's Name He did His works, He teaches that the Jews blasphemed when they said that He cast out devils by Beelzebub. And since the Father does the marvellous deeds, not because He is a Father, but because He is in His Nature God; so the Son also, not because He is a Son, but as God of God, is able Himself to do the works of the Father: wherefore suitably to His Nature He said He did His works in His Father's Name.
