Saturdays with Calvin #58

Lest we should stumble at the very threshold (this we should do were we to begin the discussion without knowing what the subject is), let us first explain the meaning of the expressions, To be justified in the sight of God, to be Justified by faith or by works. A man is said to be justified in the sight of God when in the judgment of God he is deemed righteous, and is accepted on account of his righteousness; for as iniquity is abominable to God, so neither can the sinner find grace in his sight, so far as he is and so long as he is regarded as a sinner. Hence, wherever sin is, there also are the wrath and vengeance of God. He, on the other hand, is justified who is regarded not as a sinner, but as righteous, and as such stands acquitted at the judgment-seat of God, where all sinners are condemned. As an innocent man, when charged before an impartial judge, who decides according to his innocence, is said to be justified by the judge, as a man is said to be justified by God when, removed from the catalogue of sinners, he has God as the witness and assertor of his righteousness. In the same manner, a man will be said to be justified by works, if in his life there can be found a purity and holiness which merits an attestation of righteousness at the throne of God, or if by the perfection of his works he can answer and satisfy the divine justice. On the contrary, a man will be justified by faith when, excluded from the righteousness of works, he by faith lays hold of the righteousness of Christ, and clothed in it appears in the sight of God not as a sinner, but as righteous. Thus we simply interpret justification, as the acceptance with which God receives us into his favor as if we were righteous; and we say that this justification consists in the forgiveness of sins and the imputation of the righteousness of Christ.
