Part Four: The Doctrine of The Application of The Work of RedemptionIV. The Mystical Union
IV. The Mystical Union
Calvin repeatedly expresses the idea that the sinner cannot share in the saving benefits of Christ's redemptive work, unless he be in union with Him, and thus emphasizes a very important truth. As Adam was the representative head of the old humanity, so Christ is the representative head of the new humanity. All the blessings of the covenant of grace flow from Him who is the Mediator of the covenant. Even the very first blessing of the saving grace of God which we receive already presupposes a union with the Person of the Mediator. It is exactly at this point that we find one of the most characteristic differences between the operations and blessings of special and those of common grace. The former can be received and enjoyed only by those who are in union with Christ, while the latter can be and are enjoyed also by those who are not reckoned in Christ, and therefore are not one with Him. Every spiritual blessing which believers receive flows to them out of Christ. Hence Jesus in speaking of the coming Paraklete could say unto His disciples: "He shall glorify me; for He shall take of mine, and shall declare it unto you," John 16:14. Subjectively, the union between Christ and believers is effected by the Holy Spirit in a mysterious and supernatural way, and for that reason is generally designated as the unio mystica or mystical union.
A. NATURE OF THE MYSTICAL UNION.
Lutherans generally treat the doctrine of the mystical union anthropologically, and therefore conceive of it as established by faith. Hence they naturally take it up at a later point in their soteriology. But this method fails to do full justice to the idea of our union with Christ, since it loses sight of the eternal basis of the union and of its objective realization in Christ, and deals exclusively with the subjective realization of it in our lives, and even so only with our personal conscious entrance into this union. Reformed theology, on the other hand, deals with the union of believers with Christ theologically, and as such does far greater justice to this important subject. In doing so it employs the term "mystical union" in a broad sense as a designation not only of the subjective union of Christ and believers, but also of the union that lies back of it, that is basic to it, and of which it is only the culminating expression, namely, the federal union of Christ and those who are His in the counsel of redemption, the mystical union ideally established in that eternal counsel, and the union as it is objectively effected in the incarnation and the redemptive work of Christ.
1. THE FEDERAL UNION OF CHRIST WITH THOSE WHOM THE FATHER HAS GIVEN HIM, IN THE COUNSEL OF REDEMPTION. In the counsel of peace Christ voluntarily took upon Himself to be the Head and Surety of the elect, destined to constitute the new humanity, and as such to establish their righteousness before God by paying the penalty for their sin and by rendering perfect obedience to the law and thus securing their title to everlasting life. In that eternal covenant the sin of His people was imputed to Christ, and His righteousness was imputed to them. This imputation of the righteousness of Christ to His people in the counsel of redemption is sometimes represented as a justification from eternity. It is certainly the eternal basis of our justification by faith, and is the ground on which we receive all spiritual blessings and the gift of life eternal. And this being so, it is basic to the whole of soteriology, and even to the first stages in the application of the work of redemption, such as regeneration and internal calling.
2. THE UNION OF LIFE IDEALLY ESTABLISHED IN THE COUNSEL OF REDEMPTION. In the case of the first Adam there was not only a federal, but also a natural and organic union between him and his descendants. There was the tie of a common life between him and all his progeny, and this made it possible that the blessings of the covenant of works, if these had eventuated, could have been passed on to the whole organism of mankind in an organic way. A somewhat similar situation obtained in the case of the last Adam as the representative Head of the covenant of redemption. Like the first Adam, He did not represent a conglomeration of disjointed individuals, but a body of men and women who were to derive their life from Him, to be united by spiritual ties, and thus to form a spiritual organism. Ideally this body, which is the Church, was already formed in the covenant of redemption, and formed in union with Christ, and this union made it possible that all the blessings merited by Christ could be passed on to those whom He represented in an organic way. They were conceived of as a glorious body, a new humanity, sharing the life of Jesus Christ. It was in virtue of that union, as it was realized in the course of history, that Christ could say: "Behold, I and the children whom God hath given me," Heb. 2:13.
3. THE UNION OF LIFE OBJECTIVELY REALIZED IN CHRIST. In virtue of the legal or representative union established in the covenant of redemption Christ became incarnate as the substitute for His people, to merit all the blessings of salvation for them. Since His children were sharers in flesh and blood, "He also in like manner partook of the same; that through death He might bring to nought him that had the power of death, that is the devil; and might deliver all them who through fear of death were all their lifetime subject to bondage," Heb. 2:14,15. He could merit salvation for them just because He already stood in relation to them as their Surety and Mediator, their Head and Substitute. The whole Church was included in Him as her Head. In an objective sense she was crucified with Christ, she died with Him, she arose in Him from the dead, and was made to sit with Him in the heavenly places. All the blessings of saving grace lie ready for the Church in Christ; man can add nothing to them; and they now only await their subjective application by the operation of the Holy Spirit, which is also merited by Christ and is sure of progressive realization in the course of history.
4. THE UNION OF LIFE SUBJECTIVELY REALIZED BY THE OPERATION OF THE HOLY SPIRIT. The work of Christ was not finished when He had merited salvation for His people and had obtained actual possession of the blessings of salvation. In the counsel of redemption He took it upon Himself to put all His people in possession of all these blessings, and He does this through the operation of the Holy Spirit, who takes all things out of Christ, and gives them unto us. We should not conceive of the subjective realization of the mystical union in the Church atomistically, as if it were effected by bringing now this and then that individual sinner to Christ. It should be seen from the point of view of Christ. Objectively, the whole Church is in Him, and is born out of Him as the Head. It is not a mechanism, in which the parts precede the whole, but an organism, in which the whole is prior to the parts. The parts come forth out of Christ through the regenerating work of the Holy Spirit, and then continue in living relationship with Him. Jesus calls attention to this organic relationship when He says: "I am the vine, ye are the branches: he that abideth in me and I in him, the same beareth much fruit: for apart from me ye can do nothing," John 15:5. In view of what was said, it is quite evident that it is not correct to say that the mystical union is the fruit of man's believing acceptance of Christ, as if faith were not one of the blessings of the covenant which flow unto us from the fulness of Christ, but a condition which man must meet partly or wholly in his own strength, in order to enter into living relationship with Jesus Christ. Faith is first of all a gift of God, and as such a part of the treasures that are hidden in Christ. It enables us to appropriate on our part what is given unto us in Christ, and to enter ever-increasingly into conscious enjoyment of the blessed union with Christ, which is the source of all our spiritual riches.
This union may be defined as
intimate, vital, and spiritual union between Christ and His people, in virtue of which He is
the source of their life and strength, of their blessedness and
That it is a very intimate union appears abundantly from the figures
used in Scripture to describe it. It is a union as of the vine and the
branches, John 15:5,
as of a foundation and the building that is reared on it, I Pet. 2:4,5,
as of husband and
wife, Eph. 5:23-32, and as of the head and the members of the body, Eph. 4:15,16. And
even these figures fail to give full expression to the reality. It is a
union that passes
understanding. Says Dr. Hodge: "The technical designation of this
union in theological
'mystical,' because it so far transcends all the analogies of earthly
relationships, in the intimacy of its connection, in the transforming
power of its
influence, and in the excellence of its consequences."
B. CHARACTERISTICS OF THE MYSTICAL UNION.
From the preceding it appears that the term "mystical union" can be, and often is, used in a broad sense, including the various aspects (legal, objective, subjective) of the union between Christ and believers. Most generally, however, it denotes only the crowning aspect of that union, namely, its subjective realization by the operation of the Holy Spirit, and it is this aspect of it that is naturally in the foreground in soteriology. All that is said in the rest of this chapter bears on this subjective union. The following are the main characteristics of this union:
1. IT IS AN ORGANIC UNION. Christ and the believers form one body. The organic character of this union is clearly taught in such passages as John 15:5; I Cor. 6:15-19; Eph. 1:22,23; 4:15,16; 5:29,30. In this organic union Christ ministers to the believers, and the believers minister to Christ. Every part of the body serves and is served by every other part, and together they are subservient to the whole in a union that is indissoluble.
2. IT IS A VITAL UNION. In this union Christ is the vitalizing and dominating principle of the whole body of believers. It is none other than the life of Christ that indwells and animates believers, so that, to speak with Paul, "Christ is formed" in them, Gal. 4:19. By it Christ becomes the formative principle of their life, and leads it in a Godward direction, Rom. 8:10; II Cor. 13:5; Gal. 4:19,20.
3. IT IS A UNION MEDIATED BY THE HOLY SPIRIT. The Holy Spirit was in a special capacity a part of the Mediator's reward, and as such was poured out on the day of Pentecost for the formation of the spiritual body of Jesus Christ. Through the Holy Spirit Christ now dwells in believers, unites them to Himself, and knits them together in a holy unity, I Cor. 6:17; 12:13; II Cor. 3:17,18; Gal. 3:2,3.
4. IT IS A UNION THAT IMPLIES RECIPROCAL ACTION. The initial act is that of Christ, who unites believers to himself by regenerating them and thus producing faith in them. On the other hand, the believer also unites himself to Christ by a conscious act of faith, and continues the union, under the influence of the Holy Spirit, by the constant exercise of faith, John 14:23; 15:4,5; Gal. 2:20; Eph. 3:17.
5. IT IS A PERSONAL UNION. Every believer is personally united directly to Christ. The representation that the life which is in the Church through Christ flows from the Church into the individual believer is decidedly unScriptural, not only in its sacramentarian but also in its pantheistic form (Rome, Schleiermacher, and many modern theologians). Every sinner who is regenerated is directly connected with Christ and receives his life from Him. Consequently the Bible always emphasizes the bond with Christ, John 14:20; 15:1-7; II Cor. 5:17; Gal. 2:20; Eph. 3:17,18.
6. IT IS A TRANSFORMING UNION. By this union believers are changed into the image of Christ according to his human nature. What Christ effects in His people is in a sense a replica or reproduction of what took place with Him. Nor only objectively, but also in a subjective sense they suffer, bear the cross, are crucified, die, and are raised in newness of life, with Christ. They share in a measure the experiences of their Lord, Matt. 16:24; Rom. 6:5; Gal. 2:20; Col. 1:24; 2:12; 3:1; I Pet. 4:13.
C. ERRONEOUS CONCEPTIONS OF THE MYSTICAL UNION.
There are several erroneous conceptions of the mystical union, against which we should be on our guard. Errors on this point should not be regarded as inconsequential and therefore unimportant, for they are fraught with danger for a true understanding of the Christian life.
1. RATIONALISTIC ERROR. We must avoid the error of the Rationalist who would identify the mystical union with the union of Christ as the Logos with the whole creation or with the immanence of God in all human spirits. This is found in the following statement, which A. H. Strong quotes from Campbell, The indwelling Christ: "In the immanence of Christ in nature we find the ground of his immanence in human nature. . . . A man may be out of Christ, but Christ is never out of him. Those who banish him he does not abandon." In this view the mystical union is robbed of its soteriological significance.
2. MYSTICAL ERROR. Another dangerous error is that of the Mystics who understand the mystical union as an identification of the believer with Christ. According to this view there is in it a union of essence, in which the personality of the one is simply merged into that of the other, so that Christ and the believer do not remain two distinct persons. Even some of the Lutherans went to that extreme. One extremist did not hesitate to say, "I am Christ Jesus, the living Word of God; I have redeemed thee by my sinless sufferings."
3. SOCINIAN AND ARMINIAN ERROR. Quite another extreme is found in the teachings of Socinians and Arminians, who represent the mystical union as a mere moral union, or a union of love and sympathy, like that existing between a teacher and his pupils or between friend and friend. Such a union does not involve any interpenetration of the life of Christ and that of believers. It would involve no more than loving adherence to Christ, friendly service freely rendered to him, and ready acceptance of the message of the Kingdom of God. It is a union that does not call for a Christ within us.
4. SACRAMENTARIAN ERROR. Another error to be avoided is that of the sacramentarians, represented by the Roman Catholic Church and by some Lutherans and High Church Episcopalians. Strong speaks of this as "perhaps the most pernicious misinterpretation of the nature of this union." It makes the grace of God something substantial, of which the Church is the depositary, and which can be passed on in the sacraments; and completely loses sight of the fact that the sacraments cannot effect this union, because they already presuppose it.
D. THE SIGNIFICANCE OF THE MYSTICAL UNION.
1. The mystical union in the sense in which we are now speaking of it is not the judicial ground, on the basis of which we become partakers of the riches that are in Christ. It is sometimes said that the merits of Christ cannot be imputed to us as long as we are not in Christ, since it is only on the basis of our oneness with Him that such an imputation could be reasonable. But this view fails to distinguish between our legal unity with Christ and our spiritual oneness with Him, and is a falsification of the fundamental element in the doctrine of redemption, namely, of the doctrine of justification. Justification is always a declaration of God, not on the basis of an existing condition, but on that of a gracious imputation, —— a declaration which is not in harmony with the existing condition of the sinner. The judicial ground for all the special grace which we receive lies in the fact that the righteousness of Christ is freely imputed to us.
2. But this state of affairs, namely, that the sinner has nothing in himself and receives everything freely from Christ, must be reflected in the consciousness of the sinner. And this takes place through the mediation of the mystical union. While the union is effected when the sinner is renewed by the operation of the Holy Spirit, he does not become cognizant of it and does not actively cultivate it until the conscious operation of faith begins. Then he becomes aware of the fact that he has no righteousness of his own, and that the righteousness by which he appears just in the sight of God is imputed to him. But even so something additional is required. The sinner must feel his dependence on Christ in the very depths of his being, —— in the sub-conscious life. Hence he is incorporated in Christ, and as a result experiences that all the grace which he receives flows from Christ. The constant feeling of dependence thus engendered, is an antidote against all self-righteousness.
3. The mystical union with Christ also secures for the believer the continuously transforming power of the life of Christ, not only in the soul but also in the body. The soul is gradually renewed in the image of Christ, as Paul expresses it, "from glory to glory, even as by the Spirit of the Lord." II Cor. 3:18. And the body is consecrated in the present to be a fit instrument of the renewed soul, and will at last be raised up in the likeness of Christ's glorified body, Phil. 3:21. Being in Christ, believers share in all the blessings which He merited for his people. He is for them a perennial fountain springing into everlasting life.
4. In virtue of this union believers have fellowship with Christ. Just as Christ shared the labours, the sufferings, and the temptations of His people, they are now made to share His experiences. His sufferings are, in a measure, reproduced and completed in the lives of His followers. They are crucified with Him, and also arise with Him in newness of life The final triumph of Christ also becomes their triumph. Rom. 6:5,8; 8:17; II Cor. 1:7; Phil. 3:10; I Pet. 4:13.
5. Finally, the union of believers with Christ furnishes the basis for the spiritual unity of all believers, and consequently for the communion of the saints. They are animated by the same spirit, are filled with the same love, stand in the same faith, are engaged in the same warfare, and are bound for the same goal. Together they are interested in the things of Christ and His Church, of God and His Kingdom. John 17:20,21; Acts 2:42; Rom. 12:15; Eph. 4:2,3; Col. 3:16; I Thess. 4:18; 5:11; Heb. 3:13; 10:24,25; Jas. 5:16; I John 1:3,7.
QUESTIONS FOR FURTHER STUDY: What is the meaning of the term 'mystical' as applied to the union with Christ? What is the relation between grace in the legal, and that in the moral sphere? How should we answer the contention that the sinner cannot become a participant in the blessings of God's special grace until he is subjectively incorporated in Christ? What can be said in reply to the assertion that faith precedes regeneration, because it effects the union with Christ, while regeneration is the fruit of this union? Does the mystical union suppress or does it preserve the personality of man? Cf. Eph. 4:13. Do all believers derive equal benefits from this union? If this union is indissoluble, how must John 15:1-7 be understood? What is Schleiermacher's conception of the believer's union with Christ?
