Dr. Marcus Johnson in his book One With Christ seeks to revitalize a critically important theological doctrine that has seemingly been lost in today’s evangelical and protestant articulation of salvation. Through interactions with the 16th-century reformers of Martin Luther and John Calvin, Johnson walks the reader through a reality that he realized had been neglected and forgotten, and this book takes us on the journey that he went through to rediscover this essential evangelical and protestant doctrine. This book provides a rich feast of theological proclamations, reminders, citations, and articulations of a central tenet of the Christian’s salvation in Christ. Union with Christ covers a vast multitude of theological riches that causes the reader's mind and spirit to be reinvigorated in a personal and vicarious manner that transforms the reader's understanding of their reality in Christ and God. To say this book is theologically rich is an understatement, in that, this book reignites the flames of the central passion of the Christian life, which is the reality that the Christian has been reincorporated into the Triune Godhead through being united to Christ. Johnson in this book has represented the feast, the treasure, and the riches that are at the center of our salvation. Johnson has indeed written a landmark theological piece that is a book that every confessional protestant evangelical pastor, leader, and student must-read.
Johnson’s central thesis of his book is that “the primary, central, and fundamental reality of salvation is our union with Jesus Christ, because of which union all the benefits of the Savior flow to us, and through which union all these benefits are to be understood.” (29) Johnson begins his book by providing an introduction where he explains his journey to arrive at this doctrine and why he believes this doctrine has been so neglected in the evangelical and protestant church. Before beginning to go through the central aspects of doctrinal articulation in regards to the Christians’ salvation, in chapter 1 Johnson provides prolegomena by explaining the nature of union with Christ. In chapter 2 Johnson goes over the fallen nature of man in how sin has been imputed to them and the reality of how the incarnation begins the Christians union with Christ. Through chapters 3-6 Johnson describes the various benefits that the Christian receives in their union with Christ, which covers justification, sanctification, adoption, sonship, preservation, and glorification. In chapter 7 Johnson covers another reality of the Christians’ salvation in their union with Christ in their incorporation into the church. Chapter 8 describes the theological importance of the word and sacraments as a reality of who the Christian is in Christ.
Johnson writes his book with a well-educated evangelical protestant in mind and writes his book with the presupposition that the reader of the book sees the 16th-century reformers, John Calvin, and Martin Luther as authoritative and orthodox theologians. To establish the beginning of his argument Johnson first begins by establishing the reality that the notion and importance of union with Christ was a doctrine that was an adamant, personal, and vital reality to the reformers. This establishment of the authority of what Johnson is writing coincides with his further explanations as to why this doctrine has been lost to the current children of the reformation in the evangelical and protestant world. Johnson provides four key reasons why this has been neglected, he says that it is a lack of engagement with sources that emphasize this doctrine, the lowering of the importance of doctrines that make salvation personal/organic/participatory, the reality that evangelicalism does not examine where it has come from, and its influence from enlightenment rationalism which coincides with a resistance to embrace mystery. These four reasons provide Johnson with an avenue to have the reader examine sources that embrace the doctrine of union with Christ, explain the importance of personal doctrines, examine the roots of evangelicalism, and see the theological reality of the mystery.
In chapter one, Johnson provides prolegomena for union with Christ where he articulates the nature of union with Christ. In this chapter the scope of union with Christ is established so that the reader may understand how important, vital, and large of a doctrine that union with Christ is. He establishes that it is a reality that is past, present, and future in that union with Christ involves the Christians election, salvation, and glorification. The essential pieces of union with Christ that Johnson presents is that it is Trinitarian, personal, intimate, vital, organic, and a profound mystery. Johnson’s usage of emphasizing these aspects of union with Christ coincides with his argument in the introduction that evangelicalism has neglected these aspects of who God is and therein neglecting the doctrine of union with Christ. In his establishment of the prolegomena for union with Christ, Johnson also, like articulating doctrine, defines what union with Christ is not. He makes a key negation in this section by stating that union with Christ does not mean deification. He says, “affirming, as we have, that believers are truly joined to Jesus Christ in the fullness of his divine him in person…is not the same thing as affirming that Christians become Gods or gods” (50). There are two other negations that Johnson makes, he states that union with Christ is not a description of the human faith experience and that union with Christ is not just “mere legal and moral notions” (54).
In the second chapter, Johnson goes on to establish the necessity for the Christian to be united with Christ through articulating the effects of sin and the necessity of the incarnation. To avoid union with Christ being a mere legal transaction, Johnson effectively dismantles the notion of federalism, that Adam was a mere representative of humankind. Johnson proposes that Augustinian realism is the reality of the fall of man, in that “the total life of humanity was then in Adam; the race as yet had it is being only in him.” (Augustus, 619). Through this doctrine of imputation, Johnson says that “we experience both the built and condemnation of his primal trespass, as well as the corrupt condition into which he fell '' (75). This setup creates a strong argument to establish the necessity for mankind to be united to Christ since all of mankind was organically present in Adam at the fall. Johnson then articulates the beginning of the Christian’s real union with Christ through articulating the reality of the incarnation and how the incarnation was the beginning of the Christian real union with Christ. The interaction between the incarnation and penal substitutionary atonement is briefly articulated and Johnson concludes that “the incarnation provides the personal grounds for the forensic benefits that flow from Christ’s substitutionary death” (84). Johnson deliberately does not spend much time articulating penal substitutionary atonement since this has taken primacy in most evangelical articulations of soteriology, which creates room for the reader to realize the importance of union with Christ.
In chapters three, four, five, and six Johnson goes over the central benefits of union with Christ which are justification, sanctification, adoption, sonship, preservation, and glorification. Johnson establishes the notion that these realities are not only benefits but are ontological realities through union with Christ by following each chapter with the benefit and its relationship to being “in Christ” as opposed to “a result of” or “because of.” Johnson’s usage of stating each benefit in its relationship to being “in Christ” is a deliberate choice to reflect and articulate the organic, personal, and vicarious nature of union with Christ.
In chapter three the reality of justification in Christ is articulated by defining what justification is and establishing the reality that justification and Christ are inseparable realities. Johnson articulates justification in a manner that cannot be an abstracted legal declaration, rather he articulates justification as not only being in Christ but Christ himself. Justification in Christ is broken into two key sections, the first being the passive obedience of Christ, and the second being the active obedience of Christ. Christ’s passive obedience being the remission of sins for the Christian and his active obedience is the declaration of the Christians’ righteousness as a result of their justification in Christ. Johnson effectively articulates the personal nature of justification in that, according to Johnson, justification is not merely a “forensic mechanism” (103), but rather it is a "sharing in the righteousness of Christ” (109).
After establishing the first aspect of union with Christ, Johnson then goes on to articulate the ensuing benefit of union with Christ, which is the Christian’s sanctification in Christ. To combat much of the abstractionism that has happened in modern evangelicalism, Johnson makes a key point to say that sanctification is not merely “our gratitude to God for forgiveness,” but rather it is “a manifestation of our new life in Christ” (116). Justification and sanctification, according to Johnson and Calvin, are not to be separated since “one always accompanies the other. The reason they cannot be separated, Calvin argued, is because that would be equivalent to dismembering Christ” (122). This notion of justification and sanctification being inseparable is a further demonstration by Johnson that the benefits of union with Christ are tied up in the personhood of who he is in himself. The ensuing results of sanctification are results of and manifestations of the life of Christ in that a Christian is to be mortified by their sin (the death of Christ) and be vivified to the reality of Christ (the resurrection of Christ). Through this logic, Johnson further demonstrates the personhood of Christ and his life as the result of the Christians union with Christ. Johnson further articulates that it is the role of the Holy Spirit in the life of the Christian and that the Christian is not only progressively sanctified in Christ but has already been sanctified in Christ as well. Another key point that Johnson makes to further present the onto-relationality of the Christians salvation is that sanctification is not to be confused with moralism, but rather a conforming and a further realization into the full humanity of who Christ is.
In chapter five Johnson describes another key benefit that the Christian has in their salvation which is their adoption and sonship in Christ. Johnson argues that there is no greater benefit to the Christian than their adoption and sonship into Christ, to the Father, through the power of the Spirit. He cites Packer that says, “the highest privilege that the gospel offers: higher even than justification…Adoption is higher, because of the richer relationship with God that it involves” (Packer, 206-207). The emphasis on adoption as the primary benefit of being in Christ is a strong argument that Johnson makes. Of all of the benefits of being united to Christ, there is no benefit that is more intimate and uniting than the notion of being adopted by God. It is this articulation of union with Christ that the strongest argument can be made against much of the impersonal nature of today’s evangelical discussion of soteriology. Precisely since adoption is in its essence relational, that the strongest argument can be made for the importance and reality of being united to Christ.
In chapter six Johnson articulates the benefit of being united to Christ in that the Christians is preserved by their union with Christ and is glorified in their union with Christ. Johnson effectively refutes any notions that preservation is dependent upon the actions of the Christian by articulating that the Christian’s preservation is dependent on who Christ is and in his relationship with the Father and the Spirit. This reality is further exemplified in his saying that the preservation of the Christian “is anchored in the personal relations and purposes of the Father, Son, and Spirit. The Father gives us to his Son through his Spirit orare the Spirit joins us to the Son, and through the Son to the Father. Only a breach in the common unity and will of the triune Godhead could sever us from Jesus Christ” (175). The reality of the Christians’s glorification in Christ is articulated in that it will involve the full realization of Christ’s incarnation, justification, sanctification, and adoption. In the Christian’s union with Christ glorification becomes the final consummation of all of the benefits that are received in their union with Christ.
In chapter 7 Johnson articulates the reality of the church in relation to the Christian’s union with Christ. This reality is not only a benefit but the manifestation of who Christ is in relation to those who are united to him. Johnson makes the point that the church is the “mystery of the Gospel” (192). This is stated through the articulation that salvation and the church cannot be separated since to be in Christ is to be in his body. Since Paul describes Christ as the mystery, it is the reality of the Christian being in Christ that is the reality that is the church. Johnson makes the point that the body of Christ is the church, since the body of Christ is Christ himself. Johnson says, “the Church is a living, organic communion of those who have been united into the life of the crucified, resurrected, living Jesus Christ himself—the body of Christ and the mystery of the gospel” (211).
In Chapter 8 Johnson provides an articulation of how the word and sacraments are “visible sign(s) of an invisible reality” (214). A further rebuke of much of modern day evangelicalism is articulated in Johnson’s statement that if a “church begins with a soteriology dominated by abstract, impersonal, and extrinsic categories, then the sacraments are bound to follow suit; the church is left with no other hand to play” (216). According to Johnson, a proper understanding of the importance of union with Christ is innately tied to an understanding of the importance of the sacraments. The two aspects of the sacraments are the preached word and the visible word of God (baptism & the Lord’s supper). The word being not only the proclaimed word but in the essence that Christ is the word of God and the words of God are the proclamations and manifestations of the word of God. Johnson ties this into the visible words of God by saying that, “if robustly sacramental notions of baptism and the Lord’s supper are generally foreign to, or even opposed by, contemporary evangelical Protestants, it may be because the notion of the real presence of Christ in the preached Word is similarly foreign” (220). Baptism is to be understood as God’s pledge to the Chrsitian to be incorporated in the death and resurrection of Christ through the Christians union with Christ. The Lord’s supper is not to be understood as a mere memorialistic event but rather a mysterious participation in partaking in being joined to Christ, which is the gospel.
Through this articulation Johnson has demonstrated how every aspect of the Christins salvation is a part of and a result of being united to Christ. Whether it be justification, sanctification, adoption, sonship, preservation, glorification, incorporation into the church, the preaching of the word, baptism, or the Lord’s Supper. Johnson effectively demonstrates how union with Christ is the umbrella concept in which the Christian is to understand their salvation and reality in Christ.
Throughout ``Union with Christ'' Johnson effectively defends his thesis that “the primary, central, and fundamental reality of salvation is our union with Jesus Christ” (29). There are many theological points that Johnson demonstrates effectively and there also a couple of weaknesses that could be improved upon.
The first theological exercise that Johnson does effectively is tying his central thesis and the title of the book into every sentence and word throughout the book. Johnson’s approach of providing a prolegomena in articulating why the doctrine of union with Christ has been neglected and why it is a vitally important doctrine food today, then articulating the reason for why union with Christ had to occur in the fall of Adam, and the articulation of the benefits and realities of being incorporated into Christ is an excellent demonstration of how systematic theology is to be done and demonstrated for the church. Johnson does not merely set up propositions that are unrelated to each other, but rather systematically works through the reality of union with Christ and how it incorporates into the Christian’s understanding of their salvation.
The second strong theological exercise that Johnson does is refuting the individualistic and gnostic tendencies and teachings of many of today’s modern evangelicals. Johnson does an excellent job of demonstrating how a lack of union with Christ leads to doctrines that result in abstractions from who Christ is and how Christians have been united to him. Most notably are his refutations of memoralism and how a lack of understanding of union with Christ has led to many evangelical churches embracing memorialistic notions of communion and have inadvertently developed gnostic notions of what the church is. Johnson has done an excellent job of demonstration how an understanding of union with Christ results in an understanding of communion as a mysterious reality that incorporates the presence of Christ into the bread and the wine. In regards to much of today’s modern evangelical ecclesiology Johnson has demonstrated how a proper understanding of the Christains union with Christ as physical and spiritual refutes and guards against the gonsitic notion of the church merely being those who are Christian. An orthodox ecclesiology, according to Johnson, incorporates not only the spiritual reality of the preached word but also the physical reality of the bread and wine. Johnson has masterfully accomplished the theological exercise of demonstrating union with Christ as the basis for how a church is to live out their reality in Christ.
In conclusion, Johnson has achieved a theological magnum opus that should be read and internalized by all of those who desire to lead the church and further understand the reality of their salvation. Union with Christ is truly a theological feast of who Christ is and the reality of who Christians are in Christ. May all Christians know to be of Christ is to be in Christ.
