Scripture
I know that my Redeemer lives, and at the last He will stand upon the earth. And after my skin has been thus destroyed, yet in my flesh I shall see God, whom I shall see for myself, and my eyes shall behold, and not another.
- Job 19:25-27 (ESV)
Interpretation
For he who does not say, ‘Creator,’ but ‘Redeemer,’ expressly tells of Him, Who after He created all things, appeared Incarnate amongst us, that He might redeem us from a state of bondage, and by His Passion set us free from death everlasting; and mark with what sure faith he makes himself secure in the power of His Divine Nature, of Whom it is said by Paul, "For though He was crucified through weakness, yet He liveth by the power of God." [2 Cor. 13, 4] For he says, For I know that my Redeemer liveth. As if he said in express terms; ‘The unbelievers may know that He was scourged, mocked, struck with the palms of the hand, covered with a crown of thorns, besmeared with spittings, crucified, dead: I, with sure faith, believe Him to live after death; I confess with unreserved voice, ‘that my Redeemer liveth,’ Who died by the hands of wicked men.’ And how, O blessed Job, through His Resurrection, thou trustest to the resurrection of thine own flesh, declare, I pray, in open speech...
That is, because the resurrection which He manifested in His own Person, He will one day bring to pass in ourselves as well; for the resurrection, which He exhibited in Himself, He pledged to us; seeing that the members follow the glory of their Head. Thus our Redeemer underwent death, that we might not fear to die; He manifested the resurrection, that we might have a sure hope that we are capable of rising again.
+ St Gregory the Great, Moralia in Job, Book 14
Application
A very strong proof of this destruction of death and its conquest by the cross is supplied by a present fact, namely this. All the disciples of Christ despise death; they take the offensive against it and, instead of fearing it, by the sign of the cross and by faith in Christ trample on it as on something dead. Before the divine sojourn of the Savior, even the holiest of men were afraid of death, and mourned the dead as those who perish.
But now that the Savior has raised His body, death is no longer terrible, but all those who believe in Christ tread it underfoot as nothing, and prefer to die rather than to deny their faith in Christ, knowing full well that when they die they do not perish, but live indeed, and become incorruptible through the resurrection. But that devil who of old wickedly exulted in death, now that the pains of death are loosed, he alone it is who remains truly dead. There is proof of this too; for men who, before they believe in Christ, think death horrible and are afraid of it, once they are converted despise it so completely that they go eagerly to meet it, and themselves become witnesses of the Savior's resurrection from it. Even children hasten thus to die, and not men only, but women train themselves by bodily discipline to meet it. So weak has death become that even women, who used to be taken in by it, mock at it now as a dead thing robbed of all its strength.
Death has become like a tyrant who has been completely conquered by the legitimate monarch; bound hand and foot the passers-by sneer at him, hitting him and abusing him, no longer afraid of his cruelty and rage, because of the king who has conquered him. So has death been conquered and branded for what it is by the Savior on the cross. It is bound hand and foot, all who are in Christ trample it as they pass and as witnesses to Him deride it, scoffing and saying, "O Death, where is thy victory? O Grave, where is thy sting?" [1 Corinthians 15:55]
