Archibald Alexander: Suffering the penalty is only half the requirement for justification, and Christ satisfied all

To suppose that suffering the penalty is an equivalent for obedience, and entitles to the same rewards is extremely absurd. It would be to suppose that Jehovah who loveth righteousness and hateth iniquity, would be as well pleased with sin, accompanied with its due punishment, as with perfect obedience to his own most holy law. The enduring a penalty in his own person, or by another, never can entitle any one to any thing else than exemption from that which he has already endured. …

If a surety would secure the inheritance for him, he must obey the law in his stead, as well as suffer its penalty. Hence it appears evident, that justification includes more than merely the remission of sins, or it would be no justification; and although pardon is included in justification; yet the transaction receives this denomination not from the forgiveness of sin, but from the imputation of righteousness, by which the believer is constituted righteous; and by which a title to eternal life is procured for him by the merit of his surety.

Justification, therefore, is not merely the forgiveness of sin, but in addition to this, a declaration that the justified person has a right to the blessings promised. He not only obtains deliverance from the sentence of condemnation, but instantly is constituted an heir of God, a joint-heir with Christ in the heavenly inheritance.

Archibald Alexander: We are justified by imputation of Christ's righteousness

"But how can his righteousness become ours? How can we be justified by his obedience? In no conceivable way, but by the imputation of his righteousness to us. No part of evangelical doctrine has met with a more determined opposition, than the doctrine of imputation. It has been loaded with reproaches, as a doctrine the most unreasonable, the most dangerous, and the most impious. It is a remarkable circumstance, however, that all the objections which have been made to it are founded on a misapprehension, or a misrepresentation of the true nature of imputation. It has been objected, that it implies the transfer of personal acts, and the communication of the moral character of one to another, which things are manifestly impossible. But this is an entire mistake. Imputation implies no change, whatever, in the inherent character of the person to whom righteousness is imputed; or to speak more correctly, though there is a renovation of nature effected at the same time, this is not by the act of imputation. By this act, the legal relations of the sinner are changed. Whereas, before righteousness was imputed, he was condemned, he is now justified. His guilt, or liableness to punishment, is taken away, and the Judge views him as standing fair in the eye of law; not considered in his own righteousness, but as clothed with the righteousness of the surety. His debt is cancelled, because another has paid it, and has caused it to be set to his credit.

...

"When God imputes the righteousness of Christ to a sinner, he actually bestows it upon him for all the purposes of his complete justification. The sinner owes a righteousness to the law, which he cannot pay; but God in mercy reckons to him the perfect righteousness of another. For the sake then of Christ's satisfaction to the precept and penalty of the law he is pardoned and accepted as having a perfect righteousness in his Surety.

...

"But the only case which furnishes a complete parallel to the imputation of Christ's righteousness to believers, is the imputation of Adam's first sin to all his posterity, on account of their double connection with him, first as their natural progenitor; and secondly as their federal head and legal representative in the first covenant. Upon these principles, there must be a union formed with Christ, before his acts of obedience to the law, and satisfaction to its penalty can be imputed to us. The first step towards this union is Christ's assumption of our nature, by which he becomes truly a man, like unto us, sin only excepted -- bone of our bone, and flesh of our flesh. But this union is not yet sufficiently intimate. As a man, Christ was equally united to our whole race; but before his righteousness can properly be imputed to us, we must become one with him by a close, and spiritual union. No truth of Scripture is more prominent or more strikingly illustrated than Christ's union with his elect people. He is the head, and they are the members; which, though many, constitute but 'one body.' He is the vine, they are the branches, and derive all their life and fruitfulness from him. He is the foundation of the spiritual temple, they are living stones builded upon this elect and precious corner stone. And lastly, He is the husband, and the spiritual Church is the spouse. 'For as the husband is the head of the wife, even as Christ is the Head of the Church,' (Ephes. v. 23.) Where the apostle carries out the resemblance to a great length. Now if we inquire how this union is formed, it will readily appear that it is by the indwelling of the Holy Spirit. 'If any man have not the Spirit of Christ he is none of his,' (Horn. viii. 9.) The converse of which is implied, If any man have the Spirit of Christ he is his. 'For as the body is one and hath many members, and all the members of that one body being many are one body, so also is Christ. For by one Spirit are we all baptized into one body,' (1 Cor xii. 12, 13.) The whole context shows, that the bond which unites all Christians to their Head, and to one another, so as to constitute one body, is the Holy Spirit. And in another place, the apostle says 'He that is joined to the Lord is one spirit.' The soul thus united to Christ and a part of his mystical body, is brought into so close and intimate a union with him, that a foundation is laid for the imputation of his righteousness to them. But as God chooses to deal with his people according to the free and rational nature with which they are endowed, he has connected their justification, which is the commencement of their actual salvation, with their faith in Christ, which is the first act of the soul united to Christ, and by which Christ is apprehended and received. It is common to say that faith unites the soul to Christ; it would be more correct to say, that faith was the first fruit of this union, and its sure indication. Thus it appears, that we are clothed with this perfect and unspotted robe of our Redeemer's righteousness, as soon as we become one with him. He is now in reality our Mediator and sponsor; our wisdom and righteousness; and thus are we justified by faith, as the act or instrument by which we apprehend and receive Christ's righteousness. It is evident from what has just been said, that it is not every kind of faith which justifies; but only that which is produced by the Holy Spirit. It is the act of the soul which is united to Christ. Not such a historical assent as men commonly give to human testimony, but a lively, and deep persuasion of the truth and excellence of divine things, grounded on the illumination of the mind by the Holy Spirit. There is that in the truth of God which, when spiritually discerned, carries with it convincing evidence of its divine origin. A true faith is not a mere intellectual act which leaves the heart unaffected with the truth believed, but such a full persuasion of the excellence as well as the truth of God's revealed will, that it carries the heart along, and sweetly inclines the will to receive Christ as he is exhibited in the Gospel. As Christ, as our Redeemer, is the central object in divine revelation; so he is the primary object of justifying faith. There can be no faith where Christ is not known. ... Of these figurative expressions, no one is more frequently used, or better suited to express the whole of a genuine faith, than that of 'receiving' Christ."

(Archibald Alexander, "A Treatise on Justification by Faith")

Biblical words for "imputation" and "justification" refer to God's objective work, not subjective, internal, progressive moral reformation within man

"The true import of the word 'justify' seems to have been corrupted among the Romanists, when the Latin Vulgate alone was taken as the guide; for the Latin word, from which our English term is derived, taken aside from its use seems to carry with it the signification, not of declaring, but making a man just; but in the original terms, both in the Hebrew and Greek, there is no ambiguity. The words express uniformly the sense which we have put on them; that is, they mean, to account, to esteem, to declare a person to be just or righteous, and never to make a man just or righteous by the infusion of grace. Justification and Sanctification should, therefore, be carefully distinguished, although they should never be separated. The difference between these two benefits which arise from union with Christ, is well expressed in the answer to the 77th Question, in our Larger Catechism. 'Although sanctification be inseparably joined with justification, yet they differ, in that, God in justification imputeth the righteousness of Christ, in sanctification his Spirit infuses grace, and enableth the exercise thereof: in the former, sin is pardoned, in the other, it is subdued: the one doth equally free all believers from the avenging wrath of God, and that perfectly in this life, that they never fall into condemnation: the other is neither equal in all, nor in this life perfect in any, but growing up to perfection." (Archibald Alexander, “A Treatise on Justification by Faith Alone”)


"To inquire what is meant by the imputation of this righteousness; which is the way in which it becomes ours and indeed is the only way in which it can become ours. The Hebrew word כשח in Genesis 15:6 and the Greek word logizwmai used by the apostle here, signifies to estimate, reckon, impute, or place something to the account of another. So the righteousness of Christ is estimated, reckoned, and imputed to be his people's, and is placed to their account as such by God the Father, and looked upon as much by him as their justifying righteousness or as though it had been wrought by them, in their own persons. That this righteousness becomes ours this way, is manifest. For in the same way that Adam's sin became ours, the same way the righteousness of Christ becomes ours; or the same way we are made sinners by the disobedience of Adam, are we made righteous by the obedience of Christ (Rom. 5:19). For as by one man's disobedience, many were made sinners. So by the obedience of one, shall many be made righteous. Now Adam's sin became ours, or we were made sinners, through his sin; by imputation, it was reckoned, it was placed to the account of all his posterity. So Christ's righteousness becomes ours, or we are made righteous, through that righteousness of his; by the imputation of it to us, it is reckoned, it is placed to our account. Again, the same way our sins became Christ's, Christ's righteousness becomes ours, as appears from 1 Corinthians 5:21. He who knew no sin, was made sin for us, that we might be made the righteousness of God in him. Now the way in which Christ was made sin for us, was by imputation; he never had any sin inherent in him, though he had it transferred unto him and laid upon him. So the way in which we are made the righteousness of God, must be by the imputation of Christ's righteousness, and indeed we cannot be made righteous any other way, than by imputation. For the objects of justification are ungodly persons in themselves; for God justifies the ungodly, as in the verse preceding my text. Now if they are ungodly in themselves, then they are not justified by a righteousness of their own, it must be by the righteousness of another. And if they are justified by the righteousness of another, that other's righteousness must be some way or other made theirs, it must be placed to their account, and reckoned as their own, which is only done by an imputation of it to them." (John Gill, "The DOCTRINE OF IMPUTED RIGHTEOUSNESS Without Works Asserted And Proved")


“I may also remind you that Augustine, and a few of the other fathers, misled by this etymology, and their ignorance of Greek, conceived and spoke of justification as a change of moral state, as well as of legal condition. Here is the poisonous germ of the erroneous doctrine of the Scholastics and of Trent concerning it; a striking illustration of the high necessity of Hebrew and Greek literature, in the teachers of the Church.” (R.L. Dabney, “Systematic Theology”)

Archibald Alexander: Christ satisfied all requirements that the first Adam failed to perform

Archibald Alexander explains, in terms of the covenant of works, that Christ satisfied the penalty and purchased the reward of eternal life for all His elect, given that paying the penalty did not do away with the preceptive requirements of perfect holiness with respect to the law:

Suppose that the first Adam had continued to obey until his probation was finished, would any one think that afterwards either he or his posterity would be freed from the obligation to be holy? Well, what he failed to do, the second Adam has performed, but the obligation to be holy is immutable. It may be asked, does the law of God require a double obedience, one from our surety, and one from ourselves? We answer, that it requires but one righteousness in order to our justification; but it requires that the justified person continue in conformity with its holy precepts. Our obedience is not now required as a condition of justification; to entertain such an opinion would be to leave the covenant of grace, and to go back to the old covenant of works. It would be to fall from grace, as Paul expresses it, that is from the doctrines of grace. Suppose each one of us had a probation for life under the law, and that we had completed our obedience and obtained justification, we should be required to render no more obedience with a view to being justified, for this is supposed to be already done. But the obligation to obey God would not cease, because we were in a justified state. We would still be required to be conformed to the law, because that was our reasonable service, arising out of our natural relations to our Creator, and because holiness is pleasing to God, beneficial to men, and essential to the promotion of our own happiness. (Archibald Alexander, A Treatise on Justification by Faith)

Archibald Alexander: Without "Sola Fide," the whole Christian system is lost, echoing Luther

Archibald Alexnader explains the central importance of justification by faith alone within Christian theology:

"How shall a man be just with God?" is surely the most important question which can possibly be conceived. … On some other points error may exist, and yet the state of the person entertaining it may notwithstanding be safe; he may still be in the right way to heaven. But a mistake, as to the method of acceptance with God, must be exceedingly dangerous: it must mislead the inquirer from the way of salvation. Let every man, then, as he regards his own eternal happiness, beware of embracing a false doctrine on this subject. … Wherever, and whenever, justification by faith, has been given up, obscured, or neglected to be preached, then and there, other errors have come in like a flood, and true religion has declined. … [Luther’s] pithy and striking declaration, that it was "the article of a standing or falling church," has often been cited; but another saying of this great reformer, equally pithy and important, is less known. "The doctrine of justification being lost," says he "the whole system of Christian doctrine is lost." (Archibald Alexander, A Treatise on Justification by Faith Alone)

Archibald Alexander: The righteousness of Christ alone is the ground of justification

Archibald Alexander explains that Christ's perfect obedience in keeping the law and satisfying the penalty encompasses the righteousness by which we are justified:

By the righteousness of Christ, we mean, all that he did and suffered to satisfy the broken law of God, for those whose salvation he undertook to secure. … as has been correctly observed by Dr. Owen and others, 'in suffering he obeyed, and in obeying he suffered.' It is sufficient, that we find in him, a full satisfaction both to the penal and preceptive requisitions of the law. (Archibald Alexander, A Treatise on Justification by Faith Alone)

Archibald Alexander: Justification is grounded in the imputation of Christ's active and passive obedience

Archibald Alexander explains that Christ's preceptive and penal obedience alone are the basis for our pardon and acceptance with God:

When God imputes the righteousness of Christ to a sinner, he actually bestows it upon him for all the purposes of his complete justification. The sinner owes a righteousness to the law, which he cannot pay; but God in mercy reckons to him the perfect righteousness of another. For the sake then of Christ's satisfaction to the precept and penalty of the law he is pardoned and accepted as having a perfect righteousness in his Surety.
