Augustine concludes his Handbook on Faith, Hope, and Love with a discussion of Christ’s saving work, the forgiveness and new life we receive in baptism, and a brief meditation on the final judgment.

Recall that for Augustine we are condemned on account of original sin – the guilt imputed to us because of our first parents’ sin – and actual sins we have committed (though infants are guilty only of the former). Christ, then, is the sacrifice that washes away all sins, original and actual. “Although he himself committed no sin, yet because of ‘the likeness of sinful flesh’ in which he came, he was himself called sin and was made a sacrifice for the washing away of sins.”

Augustine goes on to describe how Christ takes away our sins in a way that to my ears sounds very Lutheran:

The God to whom we are to be reconciled hath thus made him the sacrifice for sin by which we may be reconciled. He himself is therefore sin as we ourselves are righteousness–not our own but God’s, no in ourselves but in him. Just as he was sin–not his own but ours, rooted not in himself but in us–so he showed forth through the likeness of sinful flesh, in which he was crucified, that since sin was not in him he could then, so to say, die to sin by dying in the flesh, which was “the likeness of sin.” And since he had never lived in the old manner of sinning, he might, in his resurrection, signify the new life which is ours, which is springing to life anew from the old death in which we had been dead to sin.

This passage hits a couple of favorite Lutheran themes such as the “happy exchange” and the notion of “alien righteousness.” Christ takes our sin and we receive his righterousness. We have no righteousness or standing before God of our own, but we have Christ. It’s very easy to see how passages like this influenced Luther.

And we receive Christ and his righteousness by being united to his saving death in baptism:

This is the meaning of the great sacrament of baptism, which is celebrated among us. All who attain to this grace die thereby to sin–as he himself is said to have died to sin because he died in the flesh, that is, “in the likeness of sin”–and they are thereby alive by being reborn in the baptismal font, just as he rose again from the sepulcher. This is the case no matter what the age of the body.

In baptism we die to all our sins – original and actual – to all the sins which we have already committed by thought, word, and deed. This is true as much for the lifelong sinner as for the newborn infant. Since Christ died to sin once and for all, defeating the power of sin, we, in being joined to his death by the waters of baptism die to sin as well.

The death of Christ crucified is nothing other than the likeness of the forgiveness of sins–so that in the very same sense in which the death is real, so also is the forgiveness of our sins real, and in the same sense in which his resurrection is real, so also in us is there authentic justification.

Such a high view of justification by grace, though, always seems to raise the dread specter of antinomianism. If we’re forgiven and justified because of Christ’s righteousness and saving death, then why not go on sinning? Laissez les bons temps rouler!

Of course we all know that Augustine, following Paul, when asked if we should sin more that grace may abound is going to respond: by no means! Christ, in his death, “died to sin” in the sense that he defeated its power. How much more, then, should we who are baptized into his death also “die to sin”? As the Apostle says “If we have died to sin, how, then, shall we go on living in it?”

Part of the idea here seems to be that because we are so closely united to Jesus in his life-giving passion and resurrection, it would be a kind of performative contradiction to go on sinning. It makes no sense for me to say that with Christ I have died to sin but can nevertheless go on sinning. If I say that it shows that I either don’t really believe it or don’t understand it.

Augustine points out that the entire sweep of Christ’s life serves as a model for the Christian life:

Whatever was done, therefore, in the crucifixion of Christ, his burial, his resurrection on the third day, his ascension into heaven, his being seated at the Father’s right hand–all these things were done thus, that they might not only signify their mystical meanings but also serve as a model for the Christian life which we lead here on the earth.

It’s interesting here that Augustine doesn’t advert to the teachings of Jesus as providing the template for the Christian life, but the whole shape of his life, especially his passion and resurrection. We are crucified with Christ, buried with Christ, and raised to new life with Christ. Quoting Paul again: “But if you have risen again with Christ, seek the things which are above, where Christ is sitting at the right hand of God. Set your affection on things above, not on things on the earth. For your are dead, and your life is hid with Christ in God.”

There is, then, a kind of “because…therefore” structure to Christian ethical imperatives. Because we have died and been buried with Christ, we therefore are dead to sin. Because we have been raised with him, we therefore have new life. This is in contrast to a “if…then” form such as “If you want to be accepted by God, then you must do x, y, or z.” The Christian life grows out of the experience of being grasped by God’s grace (preeminently in the sacrament of baptism).

Augustine concludes with a brief discussion of the Last Judgment. He acknowledges that Christians believe that Christ will come again to judge the living and the dead, but he points out that “the living and the dead” can be understood in two different senses. It could mean, literally, that Christ will judge those who are alive here on earth and those who have already died at the end of the age. But it could also refer to the “living” as those who are righteous, or destined for God’s kingdom, and the “dead” as the unrighteous. The judgment of God would then reveal one’s status as belonging to one of these two groups (elsewhere Augustine talks in more depth how here below we can’t determine empirically who belongs to the elect and who to the reprobate). Of course, these two notions aren’t mutually exclusive; God may judge the living and the dead precisely by means of establishing who the righteous and the unrighteous are.
