In its widest sense, the phrase union with Christ refers to the relationship between the believer and Jesus Christ. In this sense, John Murray says, union with Christ is "the central truth of the whole doctrine of salvation." [1] The expression "in Christ" (en Christo, en kyrio, en Christo Iesou, en auto etc.) occurs 216 times in the Pauline letters and 26 times in the Johannine literature. [2] Hence, according to Albert Schweitzer, "This 'being-in-Christ' is the prime enigma of the Pauline teaching: once grasped it gives the clue to the whole." [3] Given the large number of occurrences and the wide range of contexts, the phrase embodies a breadth of meaning. [4] (For example; Paul uses the phrase "en Christo" as a synonym for a Christian (Romans 16:7) and the phrase "en emoi" to describe the intimate identification of Christ with the believer (Galatians 2:20).)
According to the narrower sense of the phrase, used in Christian theology, union with Christ is a step in the ordo salutis ("order of salvation"), and the basis of the believer's justification. [5] In this sense, union with Christ follows faith and precedes adoption (Galatians 3:26-27). Augustus Strong describes it in this way: "union with Christ logically precedes both regeneration and justification; and yet, chronologically, the moment of our union with Christ is also the moment when we are regenerated and justified." [6]
Traditional Roman Catholic theology centres the union with Christ in a substantial sense on the unity of the institutional church, past and present. "The communion of saints is the spiritual solidarity which binds together the faithful on earth, the souls in purgatory, and the saints in heaven in the organic unity of the same mystical body under Christ its head." [7] Christians, according to Roman Catholic theology, are united to Christ through the sacraments. [8]
Medieval conceptions of union with Christ were influenced in large part by mysticism, such as in the preaching of St. Bernard of Clairvaux. St. Bernard applied the concept of bridal love in the Hebrew Bible’s Song of Songs to a “mystical union” with Christ, wherein Jesus was bridegroom & the worshipper/church (humanity) was His bride. In this conception, Jesus’ love for humanity was manifested in his sacrifice on the cross, something that was reenacted everyday in the Eucharist. In medieval mystical union theology, the sacrament of the Eucharist was the foremost conduit with which humanity found union with Christ.
In Reformed theology, union with Christ is understood to be a comprehensive category that runs through the entire doctrine of Salvation. [9] John Murray observes: "Union with Christ is a very inclusive subject. It embraces the wide span of salvation from the ultimate source in the eternal election of God to its final fruition in the glorification of the elect." [10]
Sinclair Ferguson distinguishes six categories of union with Christ. Union with Christ is federal or covenantal in the sense that Christ's obedience is accounted to believers. It is carnal or fleshly in the sense that Christ became incarnate and thus became one with humanity. Union with Christ is also a faith union in which by faith Christians depend on Christ for nourishment. It is a spiritual union because Christians are united to Christ by the agency of the Holy Spirit. It is an extensive union in that Christians are united with Christ in everything he has done, including his life, death, burial, resurrection, ascension, and session. It is finally a union of life because Christ lives in Christians and he is visible in their lives. [11]
As a step in the order of salvation, union with Christ was seen by John Calvin to be the basis for both justification and sanctification. Alister McGrath notes that while Martin Bucer suggested that justification causes (moral) regeneration, Calvin argued that "both justification and regeneration are the results of the believer's union with Christ through faith." [12]
Some Evangelicals see union with Christ as a discrete stage in the "order of salvation." [13] The evangelical theologian William Shedd comments "The impartation of Christ's righteousness presupposes a union with him." [14] Robert Dabney, while avoiding deification, said that the bond of the union is the indwelling of the Holy Spirit. [15]
Eastern Orthodox theology emphasizes the incarnation as the starting point for our union with Christ. [16] "In Christ God becomes one with us in order to make us one with him; he stooped to take our nature, in order that we might be restored to become partakers of his nature." [16]
In Christian theology the union of Christ is built on the a priori assumption of Adam's union with humanity (Romans 5:12-21). [17] Also according to the Apostle Paul, Christ's death and resurrection is a prerequisite for believers to be identified with Christ (Romans 6:8-10). [18] In other words, the vicarious death of Jesus is the basis for incorporation into Christ. [19]
The New Testament teaches that union with Christ is precipitated by faith and baptism, i.e. we believe and are baptized "into" Christ (John 3:16, Romans 6:3). Both the apostle John and Paul employ the Greek preposition eis rather than en in these passages to convey the notion of union with Christ. The ESV Study Bible explains the use of this particular preposition in its note on John 11:25, "The preposition translated “in” (Gk. eis) is striking, for eis ordinarily means “into,” giving the sense that genuine faith in Christ in a sense brings people “into” Christ, so that they rest in and become united with Christ. (This same expression is found in 3:16, 18, 36; 6:35; 7:38; 12:44, 46; 14:12; 1 John 5:10.)" [20]
I am the vine; you are the branches.
Whoever abides in me and I in him,
he it is that bears much fruit,
for apart from me you can do nothing.— John 15:5, ESV
There are a number of ways of describing the nature of the union with Christ. Roman Catholic theology holds that believers actually imbibe the physical body and blood of Christ when they partake in the Eucharist. [21] Reformed theology using the model of federal headship, where humanity is covenantally represented by Adam, sees Christians represented covenantally by Christ. [22] Pietist theology see a union with Christ as mystical, "hidden" in the spiritual dimension. [23] Evangelical theology contains the idea of an experiential union, where Jesus having gone through life, death and resurrection, shares these experiences with believers. [24] Both Reformed and Evangelical theology acknowledges that union with Christ is the subjective application of God's objective work in Salvation. [25] In Protestant theology the phrase union with Christ means a mutual indwelling (John 14-15), of Christians and the triune God, without affirming that Christians are absorbed into God. [26] Several biblical themes are expressed within concept of being "in Christ." For example, the Old Testament notion of God dwelling among the Israelites (Exodus 25:8) is expressed by Jesus in the New Testament as the triune God dwelling with believers (John 14:23). [19]
Augustus H. Strong positively describes the nature of the believer's union with Christ with five adjectives. [27] This union is:
Born again, or to experience the new birth, is a phrase, particularly in evangelicalism, that refers to a "spiritual rebirth", or a regeneration of the human spirit. In contrast to one's physical birth, being "born again" is distinctly and separately caused by the operation of the Holy Spirit, and it is not caused by baptism in water. It is a core doctrine of the denominations of the Anabaptist, Moravian, Methodist, Baptist, Plymouth Brethren and Pentecostal Churches along with all other evangelical Christian denominations. All of these Churches strongly believe Jesus's words in the Gospels: "You must be born again before you can see, or enter, the Kingdom of Heaven." Their doctrines also mandate that to be both "born again" and "saved", one must have a personal and intimate relationship with Jesus Christ.
Justificatio sola fide, meaning justification by faith alone, is a soteriological doctrine in Christian theology commonly held to distinguish the Lutheran and Reformed traditions of Protestantism, among others, from the Catholic, Eastern Orthodox, Oriental Orthodox and Assyrian churches. The doctrine asserts that it is on the basis of faith that believers are made right of their transgressions of the law of God rather than on the basis of what Paul calls "works of the law", sometimes called good works. This forgiveness is known as "justification". In classical Lutheran and Reformed theologies, works are seen as crucial evidence of faith, but the works themselves do not determine salvation. In contrast, Methodist doctrine affirms a belief in justification by faith that offers God's forgiveness, but holds that holy living with the goal of Christian perfection (sanctification) is essential for salvation.
Perseverance of the saints is a Christian teaching that asserts that once a person is truly "born of God" or "regenerated" by the indwelling of the Holy Spirit, they will continue doing good works and believing in God until the end of their life.
In Western Christian theology, grace is created by God who gives it as help to one because God desires one to have it, not necessarily because of anything one has done to earn it. It is understood by Western Christians to be a spontaneous gift from God to people – "generous, free and totally unexpected and undeserved" – that takes the form of divine favor, love, clemency, and a share in the divine life of God. In the Eastern Orthodox Church, grace is the uncreated Energies of God. Among Eastern Christians generally, grace is considered to be the partaking of the Divine Nature described in 2 Peter 1:4 and grace is the working of God himself, not a created substance of any kind that can be treated like a commodity.
In Christianity, salvation is the "saving [of] human beings from sin and its consequences, which include death and separation from God" by Christ's death and resurrection, and the justification following this salvation.
In Christian theology, justification is the event or process by which sinners are made or declared to be righteous in the sight of God.
In Christian theology, the term Body of Christ has two main but separate meanings: it may refer to Jesus Christ's words over the bread at the celebration of the Jewish feast of Passover that "This is my body" in Luke 22:19–20, or it may refer to all individuals who are "in Christ" 1 Corinthians 12:12–14.
As a general term in theological use, assurance refers to a believer's confidence in God, God's response to prayer, and the hope of eternal salvation. In Protestant Christian doctrine, the term "assurance", also known as the Witness of the Spirit, affirms that the inner witness of the Holy Spirit allows the Christian disciple to know that he or she is justified. Based on the writings of St. Augustine of Hippo, assurance was historically an important doctrine in Lutheranism and Calvinism, and remains a distinguishing doctrine of Methodism and Quakerism, although there are differences among these Christian traditions. Hymns that celebrate the witness of the Holy Spirit, such as "Blessed Assurance" are sung in Christian liturgies to celebrate the belief in assurance.
Imputed righteousness is a concept in Christian theology proposing that the "righteousness of Christ...is imputed to [believers]—that is, treated as if it were theirs through faith." It is on the basis of Jesus' righteousness that God accepts humans. This acceptance is also referred to as justification.
Eternal security, also known as "once saved, always saved", is the belief that from the moment anyone becomes a Christian, they will be saved from hell, and will not lose salvation. Once a person is truly "born of God" or "regenerated" by the indwelling of the Holy Spirit, nothing in heaven or earth "shall be able to separate (them) from the love of God" and thus nothing can reverse the condition of having become a Christian.
The "New Perspective on Paul" is a movement within the field of biblical studies concerned with the understanding of the writings of the Apostle Paul. The "new perspective" was started with liberal scholar E. P. Sanders' 1977 work Paul and Palestinian Judaism. The old Protestant perspective claims that Paul advocates justification through faith in Jesus Christ over justification through works of the Law. After the Reformation, this perspective was known as sola fide; this was traditionally understood as Paul arguing that Christians' good works would not factor into their salvation – only their faith would count. In this perspective, first-century Second Temple Judaism is dismissed as sterile and legalistic.
The Paschal mystery is one of the central concepts of Catholic faith relating to the history of salvation. According to the Compendium of the Catechism of the Catholic Church, "The Paschal Mystery of Jesus, which comprises his passion, death, resurrection, and glorification, stands at the center of the Christian faith because God's saving plan was accomplished once for all by the redemptive death of himself as Jesus Christ." The Catechism states that in the liturgy of the Church "it is principally his own Paschal mystery that Christ signifies and makes present."
The Sinner's prayer is an evangelical Christian term referring to any prayer of repentance, prayed by individuals who feel sin in their lives and have the desire to form or renew a personal relationship with God through Jesus Christ. It is a popular prayer in evangelical circles. It is not intended as liturgical like a creed or a confiteor said or chanted within the Catholic Mass, but rather, is intended to be an act of initial conversion to Christianity; at the same time, it is roughly analogous to the Catholic Act of Contrition, though the theology behind each is markedly different, due to the intrinsically different views of salvation between Catholicism and Protestantism. While some Christians see reciting the sinner's prayer as the moment defining one's salvation, others see it as a beginning step of one's lifelong faith journey.
The theology of Martin Luther was instrumental in influencing the Protestant Reformation, specifically topics dealing with justification by faith, the relationship between the Law and Gospel, and various other theological ideas. Although Luther never wrote a systematic theology or a "summa" in the style of St. Thomas Aquinas, many of his ideas were systematized in the Lutheran Confessions.
Regeneration, while sometimes perceived to be a step in the Ordo salutis, is generally understood in Christian theology to be the objective work of God in a believer's life. Spiritually, it means that God brings a person to new life from a previous state of separation from God and subjection to the decay of death. Thus, in Lutheran and Roman Catholic theology, it generally means that which takes place during baptism. In Calvinism and Arminian theology, baptism is recognized as an outward sign of an inward reality which is to follow regeneration as a sign of obedience to the New Testament; as such, the Methodist Churches teach that regeneration occurs during the new birth.
Ordo salutis refers to a series of conceptual steps within the Christian doctrine of salvation.
Christian theology is the theology of Christian belief and practice. Such study concentrates primarily upon the texts of the Old Testament and of the New Testament, as well as on Christian tradition. Christian theologians use biblical exegesis, rational analysis and argument. Theologians may undertake the study of Christian theology for a variety of reasons, such as in order to:
Paul's theology is considered by some interpreters to center on a participation in Christ, in which one partakes in salvation by dying and rising with Jesus. While this theology was interpreted as mysticism by Albert Schweitzer, according to the New Perspective on Paul, as initiated by E.P. Sanders, it is more aptly viewed as a salvation theology.
A sacrament is a Christian rite that is recognized as being particularly important and significant. There are various views on the existence, number and meaning of such rites. Many Christians consider the sacraments to be a visible symbol of the reality of God, as well as a channel for God's grace. Many denominations, including the Catholic, Lutheran, Anglican, Methodist, and Reformed, hold to the definition of sacrament formulated by Augustine of Hippo: an outward sign of an inward grace, that has been instituted by Jesus Christ. Sacraments signify God's grace in a way that is outwardly observable to the participant.
Theosis, or deification, is a transformative process whose aim is likeness to or union with God, as taught by the Eastern Catholic Churches and the Eastern Orthodox Church. As a process of transformation, theosis is brought about by the effects of catharsis and theoria. According to Eastern Christian teachings, theosis is very much the purpose of human life. It is considered achievable only through synergy of human activity and God's uncreated energies.
