The Gospel
I begin where Romans begins – with the gospel. My proposal is this. When Paul refers to ‘the gospel’, he is not referring to a system of salvation, though of course the gospel implies and contains this, nor even to the good news that there now is a way of salvation open to all, but rather to the proclamation that the crucified Jesus of Nazareth has been raised from the dead and thereby demonstrated to be both Israel’s Messiah and the world’s true Lord. ‘The gospel’ is not ‘you can be saved, and here’s how’; the gospel, for Paul, is ‘Jesus Christ is Lord’.
This announcement draws together two things, in derivation and confrontation. First, Paul is clearly echoing the language of Isaiah: the message announced by the herald in Isaiah 40 and 52 has at last arrived. Saying ‘Jesus is Messiah and Lord’ is thus a way of saying, among other things, ‘Israel’s history has come to its climax’; or ‘Isaiah’s prophecy has come true at last’. This is powerfully reinforced by Paul’s insistence, exactly as in Isaiah, that this heraldic message reveals God’s righteousness, that is, God’s covenant faithfulness, about which more anon. Second, since the word ‘gospel’ was in public use to designate the message that Caesar was the Lord of the whole world, Paul’s message could not escape being confrontative: Jesus, not Caesar, is Lord, and at his name, not that of the Emperor, every knee shall bow. This aspect lies at the heart of what I have called ‘the fresh perspective on Paul’, the discovery of a subversive political dimension not as an add-on to Paul’s theology but as part of the inner meaning of ‘gospel’, ‘righteousness’, and so on.
For Paul, the announcement or proclamation of Jesus as Lord was itself the ‘word of God’ which carried power. Putting together the various things he says about the preaching of the gospel, the word, and the work of the Spirit, we arrive at the following position: when Paul comes into a town and declares that Jesus is Lord, no doubt explaining who Jesus was, the fact and significance of his death and resurrection, and so on, then the Spirit is at work, mysteriously, in the hearts and minds of the listeners, so that, when some of them believe in Jesus, Paul knows that this is not because of his eloquence or clever argument but because the announcement of Jesus as Lord functions as (in later technical language) the means of grace, the vehicle of the Spirit. And, since the gospel is the heraldic proclamation of Jesus as Lord, it is not first and foremost a suggestion that one might like to enjoy a new religious experience. Nor is it even the take-it-or-leave-it offer of a way to salvation. It is a royal summons to submission, to obedience, to allegiance; and the form that this submission and obedient allegiance takes is of course faith. That is what Paul means by ‘the obedience of faith’. Faith itself, defined conveniently by Paul as belief that Jesus is Lord and that God raised him from the dead, is the work of the Spirit, accomplished through the proclamation. ‘No-one can say “Jesus is Lord” except by the Holy Spirit.’ But this already jumps ahead to my fourth point, and before we get there we must take in the second and third.
