We often forget that all of Paul’s Letters were written before the Gospels. But, whereas the Gospel writers were content with recording the story of the Cross, Paul delved deep into its meaning.
The Centrality of the Cross

The Cross was central to everything that Paul understood about the work of Christ. When he arrived in Corinth he stated that he “determined to know nothing except Christ crucified”, and in Chapter I of his letter to the Corinthians he said “Jews demand signs, Greeks seek wisdom, but we preach Christ crucified”. This pre-occupation with the Cross has had dire consequences for Protestant theology. It ignores the rest of Jesus’ life. And Eastern Orthodox Christians remind us that the Incarnation (the birth at Bethlehem) was just as crucial for our salvation. The fact of the matter is that it is the whole of Jesus’ life which constitutes a single, saving act of God. The Cross (together with the Resurrection) is its climax but must not, and cannot, be separated from all that went before.
God was in Christ
A crucial text in Paul’s understanding comes in 2 Cor 5. “God was in Christ reconciling the world to Himself”. For Paul it is God who forgives, God who reconciles, God who justifies, and he does all this in and through Christ. Working with a Trinitarian concept of Father, Son and Holy Spirit we have often fallen into the trap of separating the Father and the Son in such a way as to suggest that the Father punished the Son for the sins of the world. As though Christ on the Cross appeased and placated an angry Father. Paul would have none of this. For him God was in Christ and therefore the sufferings of Christ are none other than the suffering of God Himself.
God through His Spirit
Salvation, for Paul, has two aspects. One centers on the work of Christ. The other on the work of the Holy Spirit. The difference is illustrated in a consideration of two key words in his theology: Justification and Sanctification, and can be tabulated in the following way:
|
JUSTIFICATION
What God does FOR us
in Christ.
Is a relative change
(i.e. a change in our status)
Confers pardon
Deals with sin as guilt
|
SANCTIFICATION
What God does IN us through the Spirit.
Is a real change
( i.e. a change in our nature)
Confers holiness
Deals with sin as corruption.
|
This table is somewhat of an over-simplification but it helps clarify our thinking.
Insofar as we are thinking about Paul’s understanding of the Cross we shall limit ourselves to the objective aspect of our salvation (what God does FOR us). But this is not the whole story. It must be complemented by the subjective aspect (what God does IN us). Salvation is a process, not a one-off.
The Cross in Paul’s Understanding
One line of approach is via a consideration of some of the words that Paul uses to describe what God has done through Christ with particular reference to the Cross.
| Redemption |
Reconciliation |
Justification |
REDEMPTION
There are two images behind this word. One stems from the dockyard market place where slaves were bought and sold. The other stems from the Old Testament idea or the “kinsman” who acts as redeemer.
i) The contemporary image which Paul used came from the practice of buying and selling slaves in the market place. The picture is of a prospective owner selecting a slave from the line of those on view, paying a price, and then commanding “strike off his chains and let him go free”. The slave is liberated from the bonds that bound him – but at a price.
“You are not your own. You were bought with a price.” I Cor.6 v 20
The price paid by Jesus on the Cross is the price of his own life. It is the price of forgiveness whereby we are liberated from the bondage of our guilt, set free from sin.
ii) The Old Testament image is reflected in the Book of Ruth. Ruth, a Moabite woman, returns to Bethlehem with her mother in law Naomi. She is a widow, a ‘stranger’, a refugee. She is taken in and cared for by Boaz who adopts her as a member of his own family. By this action Boaz is said to be acting as a “kinsman”. The Hebrew word can also be translated “Redeemer”. Boaz plays a kinsman’s part and accepts responsibility for Ruth.
God in Christ accepts responsibility for us. This is the meaning of His incarnation at Bethlehem. God becomes one with us, one of us. In Christ He identifies Himself with our humanity – at Bethlehem – at the Baptism in the Jordan – and on the Cross.
JUSTIFICATION
This is the most difficult concept to grasp and has given rise to much heated debate!
It is a key doctrine of St Paul.
“Therefore, since we are justified by faith, we have peace with God.” Romans 5 v 1
“We know that a man is not justified by works of the Law but through faith in Jesus Christ.” Galatians 2 v 16
The whole of Paul’s letter to the Romans is a sustained exposition on the theme of Justification by faith.
As usual Paul is working with an “everyday” picture. In this instance it is a Law Court. He imagines the defendant brought before the Judge. The defendant is patently guilty. Amazingly the Judge pronounces a verdict of “acquittal”.
Paul argues that we stand before God as guilty. But, in justifying us, God sees us as we are in Christ and acquits us. Through faith we are identified with Christ and God pronounces the verdict that He would have pronounced on Christ.
It is this idea which the eucharistic hymn expresses;

“Look, Father, look on his anointed face,
and only look on us as found in him”
But this teaching has given rise to criticism. Is it not a legal fiction for God to announce a “Not Guilty” verdict and acquit us when the reality is that we are guilty and have not changed?
What does that say about the justice of God? Such a verdict is patently unjust.
Two attempts have been made to preserve the justice of God in this situation:
Protestant theology has argued that God treats us as though we were righteous by virtue of our identification through faith with Christ. In theological terms the righteousness necessary for us to be acquitted is imputed to us. This does not remove the objection however, and so some Protestant theologians have gone further and argued that God is able to acquit us because the moment of faith gives us a righteous intent and God acquits us on the basis of that intent.
Catholic theology has tended to argue that God imparts a real righteousness to us, and on that basis he is able to justly pronounce our acquittal.
The debate and distinction between an imputed and an imparted righteousness has been long and heated and has divided Protestant and Catholic.
Part of the confusion has resulted from a misunderstanding of what “righteousness” means. To many it is an ethical quality, a kind of “goodness”. But this is not the Old Testament meaning where “righteousness” refers to the nature of a relationship. In the O.T. a man is righteous if he is in a right relationship with God. On this basis to say that we are justified means that our status viz-a-viz God is changed. We no longer stand before God as guilty sinners, but as pardoned sinners. And it is God who makes this change in relationship possible. We cannot earn it or merit it. It is offered as gift and received by faith.
Excursus
The Bible frequently uses the imagery of clothing to symbolize relationship.
Jacob’s coat of many colours symbolized his favourite son relationship with his father.
Consider the O.T. story of the Garden of Eden where man is driven from the garden i.e. from the presence of God. But God provides clothes for the man and his wife.
The theology behind this imagery is that man’s disobedience has changed the nature of his relationship to God – the man is now guilty. But God does not ex-communicate him altogether. He makes possible a different relationship and the provision of clothing symbolizes this new standing / relationship.
In the N.T. this symbolism is continued in the story of the Prodigal Son (Luke 15). The Prodigal is welcomed home as a son and not as a hired servant and to make the point his father orders him to be wrapped in the best robe; “for this my son was dead and is alive again”.
Working with this analogy Paul envisions being justified as being clothed with the righteousness of Christ. It’s a theme which Charles Wesley picked up when he sang;
“No condemnation now I dread;
Jesus and all in Him is mine,
Alive in Him, my living head,
and clothed in righteousness divine”
The Justification of God.
There is another way in which we can view the idea of Justification. It is to see it, not as the justification of man, but the justification of God.
On this understanding the Cross justifies God in forgiving us. We say that God forgives us freely. But is not the idea of free forgiveness immoral? Simply to say “I forgive you” could easily be seen as condoning the wrong action, or turning a blind eye to it, or treating it with less than seriousness. Surely justice demands that some penalty be incurred.
Some “theories” of the atonement pursue this argument by saying that the Cross represented:
God punishing His Son in the interests of justice. This penal substitutionary “theory” is quite unacceptable to many Christians.
There is another way of understanding the argument. It is to remind ourselves that the penalty (and the consequence) of sin is separation from God. God in Christ endures this consequence. (Hence the cry from the Cross “My God. why have you forsaken me?”)
Therefore the forgiveness which God offers can be seen as free to us but costly to Him. What it cost God to freely forgive us was the crucifixion of Love.
So God may be said to be justified in offering us a free forgiveness. He has borne within Himself the cost of being able to offer forgiveness. The Cross of Christ is sign and symbol of that cost.
