The effect of what he wrote, at all events about Judaism, has been to inflict what Jews feel to be a cruel injustice on their religion. To Paul himself, I imagine, it can only have appeared to be the obvious and necessary statement of the result of his changed position in religion. He has left it on record that, through his conversion, he became a new man in Christ (2 Cor. v. 17). And one of the implications of that fact is that he should no longer be able accurately to reproduce in his mind what the "old man" had felt and thought and believed; he would retain only the distant memory of discarded things. If he wrote of the religion he had left, it would be, not of what once had been his, but of what he could only judge as an external thing, variously defective when seen in the light of his present religion.
Beyond the fact, then, that by his own account Paul had been before his conversion a zealous and consistent Pharisee, we do not know what his earlier opinion had been upon any subject whatever. He does not become known to us until after his conversion; and the writings from which we gain the knowledge of him were not composed till twenty years or more had elapsed since that event. Of his conversion he says very little; not enough to enable us to understand precisely what took place. It may well be, indeed, that he himself could never have stated in words, at any time, precisely what took place, or what, if anything, led up to the change. This much, however, is beyond question, that as a result of his conversion Christ became to him the central element in his religion. All his spiritual life depended on Christ. All his thought was conditioned by his idea of Christ. All the energy of soul which was his to give for the fulfilling of his ministry he ascribed to the immediate personal influence of Christ upon him. Christ was the all and everything of his religious life; and the lines upon which his subsequent career was laid out, so that he became the Apostle of the Gentiles, were marked out by his conception of the relation in which he believed himself to stand towards Christ. In some marvellous way, it seemed that Christ had entered and taken possession of him; with the result that he became the Paul whom we know.
There must have followed a process, whether short or long, by which he adjusted himself to his altered mental position, estimated the effect of the change upon his previous beliefs and ideas, and grasped the meaning of new and unfamiliar ones. For it goes without saying that his conversion widened the scope of his thought so as to bring many things within the range of his inward vision that previously had been unnoticed or not understood, as it also changed his estimate of what had been previously there. But of the details and the order of that process we know nothing. We cannot tell, for instance, whether it began with the settling of his attitude towards Judaism, or whether he was drawn first towards the idea of salvation for the Gentiles. We only know the results long after the process was completed, when he had shaped in thought a more or less consistent theory of divine providence, as shown in the history of the world.
The opening chapter of the Epistle to the Romans shows how profoundly he was impressed by the moral chaos of the Gentile world; but the fact is mentioned there only to give the explanation of it. For an explanation was needed. Such a state of humanity was in terrible contrast to the perfection which should have been found in those whom the all-holy God had made. Doubtless there were differences of better and worse between this man and that; but, judged by the standard of perfection, i.e. of complete harmony with God, all were alike immeasurably below what they ought to be. Not only the Gentiles, but the Jews also, came under this condemnation. Jews indeed were not guilty of the loathsome vices which made the Gentile life so horrible; but it was clear that, in regard to the standard of perfection which God desired in man, the Jews wholly failed to reach it. All the world over, through all the multitude of human beings, "there was none righteous, no not one" (Rom. iii. 10).
Yet the Gentiles, Paul argued, could have known, and even did know, something of God; but they disowned that knowledge, and "glorified him not as God, neither gave thanks; but became vain in their reasonings, and their senseless heart was darkened.... Wherefore God gave them up in the lusts of their hearts ... for that they exchanged the truth of God for a lie, and worshipped and served the creature rather than the Creator" (Rom. i. 21, 24-5).
And the Jews knew well the will of God, for to them He had revealed it through Moses and the prophets; with them He had made His covenant, and had chosen them out of all the nations of the earth, to be a peculiar people unto Himself. How was it that they too fell so far short of what was required of them? Must it not have been (so Paul reasoned) because the divine Law[10] that was given them was the very means and occasion of sin? To fail in regard to one single precept was to break the harmony between man and God; and, when once that harmony was broken, there was nothing in the Law itself to restore it. By its multiplication of commandments, the Law offered so many occasions for the breaking of that harmony; and whereas it was "holy, and the commandment righteous and just and good," its ideal was one that no human effort could reach. Its effect was to multiply sin. Righteousness under the Law was impossible; meaning by righteousness the state of perfect harmony of man with God.
"But now," says Paul (Rom. iii. 21 fol.), "apart from the law a righteousness of God hath been manifested, being witnessed by the law and the prophets; even the righteousness of God through faith in Jesus Christ unto all them that believe; for there is no distinction; for all have sinned, and fall short of the glory of God; being justified freely by his grace through the redemption that is in Jesus Christ," etc.
Through faith in Jesus Christ there was offered to sinful man the means of attaining that righteousness—harmony with God—which had been vainly sought under the Law, or lost in the darkness of Gentile corruption. And this was evidently what God had willed from the beginning. Christ was the instrument, or the agent, by whom this divine purpose was to be fulfilled. And the meaning of what might seem to be the age-long delay of his coming was that God would "shut up all under sin, that he might have mercy upon all."[11]
Christ performed his divinely appointed mission by his death on the Cross, and his subsequent resurrection; having borne and discharged the obligation of the unfulfilled Law, and thereby released all, whether Jews or Gentiles, from the bondage of sin. Righteousness was now attainable through faith in Christ; and I presume that Paul meant by righteousness, harmony with God, resulting from such an attitude on the part of the believer towards Christ as that in which Paul himself stood towards him, in other words, a complete surrender of heart and will to Christ, so as to "put off the old man" and become "a new creature." Those who did this would thereby attain to perfect harmony with God, which is righteousness.
