Romans 8:13

For if you live after the flesh, you shall die: but if you through the Spirit do put to death the deeds of the body, you shall live.
Read Chapter 8

Ambrose of Milan

AD 397
It is not strange that one who puts to death the deeds of the flesh will live, since one who has the Spirit of God becomes a son of God. It is for this reason that he is a son of God, so that he may receive not the spirit of slavery but the spirit of the adoption of sons, inasmuch as the Holy Spirit bears witness with our spirit that we are sons of God.

Ambrosiaster

AD 400
Nothing is truer than this, that if we live according to Adam we shall die. For by sinning Adam was consigned to the flesh and sold himself to sin, for all sin is oriented to the flesh…. The body wants to be governed by the law of the spirit, which is why Paul shows that if we are led by the Holy Spirit the acts and desires of the flesh, which are made up by the instigation of the powers of this world, are repressed so as to be unable to act. Then we shall enjoy eternal life. Commentary on Paul’s Epistles.

Augustine of Hippo

AD 430
I have quoted this passage so that I might make use of the apostle’s words to deter your free will from evil and to exhort it to what is good. Nor should you on this account glory in man, i.e., in yourselves and not in the Lord. You are not living according to the flesh but are putting the deeds of the flesh to death by the Spirit.

Augustine of Hippo

AD 430
That we should mortify the deeds of the flesh by the Spirit is required of us, but that we may live is offered to us…. Shall we therefore agree to say that the mortification of the flesh is not a gift of God and not confess it to be a gift of God, since we hear that it is required of us, with life offered as a reward to us if we have done it? Predestination of the Saints

Augustine of Hippo

AD 430
When by our spirit we put to death the works of the flesh we are impelled by the Spirit of God, which grants the continence by which we restrain, master and overcome concupiscence.

Irenaeus of Lyons

AD 202
Paul does not prevent them from living their lives in the flesh, for he was himself in the flesh when he wrote to them, but he cuts away the lusts of the flesh which bring death upon a man. .

Irenaeus of Lyons

AD 202
And again he says, in the Epistle to the Romans, "For if ye live after the flesh, ye shall die."

John Chrysostom

AD 407
You can see from this that Paul is not talking about the essence of the body but about the evil deeds which it does. For if we stop doing evil deeds, then our physical bodies will live.

Knowing this first, that no prophecy of the scripture is of any private interpretation - 2 Peter 1:20
