Augustine of Hippo
Catena Aurea · Johannesevangelium 5
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. For as the Father hath life in himself; so hath he given to the Son to have life in himself.
(Tr. xxii. s. 12) Or, He means to guard against our thinking, that the being passed from death to life, refers to the future resurrection; its meaning being, that he who believes is passed: and therefore He says, Verily, verily, I say unto you, The hour cometh, (what hour?) and now is, when the dead shall hear the voice of the Son of God, and they that hear shall live. He saith not, because they live, they hear; but in consequence of hearing, they come to life again. But what is hearing, but obeying? For they who believe and do according to the true faith, live, and are not dead; whereas those who believe not, or, believing, live a bad life, and have not love, are rather to be accounted dead. And yet that hour is still going on, and will go on, the same hour, to the end of the world: as John says, It is the last hour. (1 John 2:13)
