For the Father loves the Son, and shows him all things that he himself does: and he will show him greater works than these, that you may marvel.
All Commentaries on John 5:20 Go To John 5
Cyril of Alexandria
AD 444
And greater works than these will He shew Him, that YE may marvel.
Above the blessed Evangelist says, The Jews were seeking to kill Jesus, because He was not only breaking the sabbath, but saying also that God was His Father, making Himself Equal with God. He therefore put down the accusation respecting the sabbath, by shewing that the Father Himself worked on the sabbath day, and expending many words thereupon: and endeavours to teach them that He is in Equality with the Father, even when made Man for our sakes (for this was what the argument yet lacked), and therefore does He say And greater works than these will He shew Him that YE may marvel. And what again does He will to shew us hereby?
The paralytic (it says) has been healed, which had an infirmity thirty and eight years. And marvellous indeed the Power of Him That healed him, God-befitting exceedingly the Authority. This so great Wonderworker, no one (I suppose) in his senses would blame for saying that He is God, and since He is Son, Equal in all things to Him That begat Him. But since ye (He says) imagining things most wicked and foolish, are offended because of this mortal Body, ye must needs learn that My Authority and Power stop not here: for ye shall be, even though ye will it not, spectators of greater wonders, to wit of the resurrection of the dead, and yet more shall ye be astonished, seeing Power and Glory befitting God, in Me Whom now ye charge with blasphemy and are not ashamed to persecute, for merely saying, I am the Son of God.
But how God the Father shews His Works to the Son, we have already said at much length.
