Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live.
All Commentaries on John 5:25 Go To John 5
Hilary of Poitiers
AD 368
The heretics, driven hard by Scripture proofs, are obliged to attribute to the Son at any rate a likeness, in respect of virtue, to the Father. But they do not admit a likeness of nature, not being able to see that a likeness of virtue, could not arise but from a likeness of nature; as an inferior nature can never attain to the virtue of a higher and better one. And it cannot be denied that the Son of God has the same virtue with the Father, when He says, What things soever (the Father) does, the same does the Son likewise. But an express mention of the likeness of nature follows: As the Father has life in Himself, so has He given to the Son to have life in Himself. In life are comprehended nature and essence. And the Son, as He has it, so has He it given to Him. Forthe same which is life in both, is essence in both; and the life, i.e. essence, which is begotten from life, is born; though not born unlike the other. For, being life from life, it remains like in nature to its origin.
Living born from living, has the perfection of nativity, without the newness of nature. For there is nothing new implied in generation from living to living, the life not coming at its birth from nothing. And the life which derives its birth from life, must by the unity of nature, and the sacrament of a perfect birth, both be in the living being, and have the being who lives it, in itself. Weak human nature indeed is made up of unequal elements, and brought to life out of inanimate matter; nor does the human offspring live for some time after it is begotten. Neither does it wholly live from life, since much grows up in it insensibly, and decays insensibly. But in the case of God, the whole of what He is, lives: for God is life, and from life, can nothing be but what is living.
For the person of the receiver, is distinct from that of the giver: it being inconceivable that one and the same person, should give to and receive from Himself. Hew ho lives of Himself is one person: He who acknowledges an Author of His life is another.
