These are the broad contrasts between the alternative methods of justification by faith or by 'works of the law.' The law, and the attitude towards God which the law suggested, are, in St. Paul's view, the main characteristic of the Old Testament. This is a point of view which we should expect in one trained by the Pharisees. We may possibly feel that St. Paul tends to identify with the Old Testament as a whole one particular element in it which specially characterized one particular period. But at least the element was there, and occupied there a highly important place in the whole development; and if St. Paul in his idealizing manner sometimes speaks as if it was the whole of the older covenant, as if he had forgotten all the teaching of prophet and psalmist, yet he is not really forgetful. Law is to him the characteristic of the old covenant. But behind the law God's dealings with Abraham are for ever in his imagination witnessing against the law's limitation, and a similar witness is kept up all along: so that St. Paul can take out of one of the books of Moses his very central statement of the principle of faith23.
In what has just been said justifying faith has been treated as if it were simply, as it is really, faith in God; whereas in St. Paul's language the object of justifying faith is constantly 'Jesus24.' The explanation of this is that in Jesus Christ God has manifested His character as Father, and has come near to men, 'reconciling the world unto Himself,' by the atonement wrought through His incarnate Son, and giving conspicuous evidence of His saving power by raising Him from the dead25. Thus, if Jesus is the proximate object of justifying faith, it is Jesus as manifesting the Father, Jesus as God incarnate; and St. Peter is strictly interpreting St. Paul when he represents the object of Christ's sacrifice and resurrection in the phrase, 'that your faith and hope might be in God26.' The faith of the Christian is the old faith of Abraham and Habakkuk, the faith in the Lord Jehovah only now made manifest in a new and completer manner, in a more intimate relation to human life, and with a more winning appeal to the human heart.
Now that we have gained a general idea of what St. Paul meant by justification by faith, as opposed to justification by works of law, we are in a position to deal with a number of questions which have been famous in ecclesiastical history. Does justification mean being made righteous, or being reckoned for righteous? if it means the latter, how can God reckon us as being what in fact we are not? Again, what is the relation of this justification to sanctification? are these two stages, of which the first is over before the second can begin? Again, what is the relation of justification to Church membership? is justification a purely individual process or fact, of which membership in the Church or, what comes to the same thing, reception of the sacraments, is a merely secondary and strictly unessential consequence?
The answers to these questions are all connected with one another. Justification, to begin with, is a judicial or, as it is called, 'forensic' word. It expresses the verdict of acquittal. The use of the word in the Bible made this quite indisputable27. Thus God justifies whenever He refuses to condemn – when, whatever may have been our sins, He ignores them, and therefore positively admits us into the accepted people. And He declares His willingness to do this simply because a man believes in Jesus Christ. Let a man believe, or take God in Jesus Christ at His gracious word, and the value of this act of trust or allegiance is such that God reckons it for righteousness, and admits a man into the accepted people, as if he were already fit for such fellowship in his actual habits or character. There is 'imputation' here, but it is the right sort of imputation. It is dealing with us not as we are, nor exactly as we are not, but as we are becoming in virtue of a new attachment under which our life has passed: and this, as the engrossing modern conception of development makes it easy for us to perceive, is the only true and profound way of regarding anything. Not the standard already reached, but the movement, direction, or vitality is the important matter. Faith, then, is 'reckoned for righteousness' because it puts us upon the right basis and in the right relation to God; and therefore is a root out of which, provided it continues to subsist, all righteousness can healthily grow; whereas the most brilliant efforts or 'works' on a wrong basis may have neither sound root nor principle of progress in them. To believe in Jesus is to have the root of the matter in oneself. Therefore, when a man first believes, God can ignore all his previous life, and deal with him simply on the new basis, in hope. Of course this preliminary acquittal or acceptance is provisional. As the servant28 who had been forgiven his debts found them rolled back upon him when he behaved in a manner utterly inconsistent with the position of a forgiven man, so our preliminary justification may be promptly cancelled by our future conduct if we behave as one who has 'forgotten the cleansing from his old sins29.' The prodigal son, after he has been welcomed home, may go back again to the 'far country.' But it remains the fact: – of such infinite value and fruitfulness is faith in God, as He has shown Himself in Jesus, that when a man first believes – aye, whenever, over and over again, he returns to believe – he is in God's sight on a new basis, however dark be the background of his previous sins; and he can be dealt with simply on the new basis, according to the movement of the Father's heart of love which his faith has set free.
Now the justifying faith of the conscience-stricken sinner, whose case St. Paul always has in the foreground of his imagination, means first of all and most obviously that he consciously takes God at His word as being ready to forgive his sins, and accept him for Jesus' sake in whom he believes. It is belief in God as forgiving, or in Jesus as – he does not stop to inquire how – obtaining and giving him forgiveness. And St. Paul laid great stress on this simple acceptance of the gift of pardon, as the gate of the new life and the first act of faith, because the readiness to be treated as a sinner and merely forgiven in spite 'f our sins is, as he knew full well in his own case, the final overthrow of spiritual pride. But this simple 'reliance on the merits of Christ,' and acceptance of forgiveness at His hands and for His sake, is a profound movement of the heart – of the spring of human actions – which involves much more than appears. Luther was hopelessly wrong and unlike St. Paul when he isolated this mere reliance on another's merits, and, setting it apart from all deeper movement of will or love, would have it, and it only, concerned with our justification. To St. Paul even the first movement of faith is a surrender of independence, and a recognition in intellect, and much more in will, of the lordship of Jesus. It is, in other words, a change of allegiance, and this is the important thing about it. And the absolved man, in thanking God for his forgiveness, finds himself, as it were, inevitably and without any fresh act, embarked on a new service. If he does not find this, he is not a man of faith at all. Faith is so deep a principle that, though it shows itself first as the mere acceptance of an undeserved boon from the divine bounty, it involves such hanging upon God as necessarily enlists the will to choose and serve Him, the intellect to know and worship Him with a growing perception as He is revealed in Jesus, and the affections to desire and love Him. The life of justification thus proceeds 'from faith to faith' – from faith in Christ 'for us' to faith in Christ 'in us.' The justified man, accepted into the 'body of Christ' by baptism and made a participator of the life of Christ, receives the continual gifts of the divine bounty in their appointed channels, and his faith exercising its natural faculty of correspondence, absorbs and appropriates the divine gifts – intellectually, so that the eyes of the understanding are opened in increasing knowledge – practically, so that 'Christ dwells in the heart by faith,' and it is no longer the bare human self which lives, but Christ which lives in the renewed man, with a continual display of moral power.
The first justification or acceptance is therefore a preliminary step: it is acceptance for admission into the divine household, or city of God, or life in Christ. It is a means to an end, and that
