Then answered Jesus and said unto them,
Verily, verily, I say unto you, The Son can do nothing of himself, but what he sees the Father do: for whatsoever things he does, these also does the Son likewise.
All Commentaries on John 5:19 Go To John 5
John Chrysostom
AD 407
Or thus; That the Son can do nothing of Himself, must be understood to mean, that He can do nothing contrary to, or displeasing to, the Father. And therefore He does not say that He does nothing contrary, but that He can do nothing; in order to show His perfect likeness, and absolute equality to the Father. Nor is this a sign of weakness in the Son, but rather of goodness. For as when we say that it is impossible for God to sin, we do not charge Him with weakness, but bear witness toa certain ineffable goodness; so when the Son says, I can do nothing of myself, it only means, that He can do nothing contrary to the Father.
And this is confirmed by what follows: For whatsoever be does these also dothe Son likewise. For it the Father does all things by Himself, so does the Son also, if this likewise is to stand good. You see how high a meaning these humble words bear. He gives His thoughts a humble dress purposely. For whenever He expressed Himself loftily, He was persecuted, as an enemy of God.
