John Calvin. This name is has different meanings depending on one’s theological framework, denominational upbringing, or knowledge of church history. He is loved by many, hated by many, and surely unknown to many others. Regardless of one’s opinion of Calvin, he is often seen as the rigid theologian who wrote extremely lofty thoughts about the sovereignty and glory of God. In his greatest theological work, The Institutes of Christian Religion, Calvin expounds rather extensively upon nearly every major Christian doctrine. However, one particular theme that is woven throughout the treatise is the practical implications of his theology. Far from a crusty old man writing a stale textbook, Calvin understood that the breadth of his work was worthless if it did not apply itself to the life of a believer. He was intensely practical and pastoral in his writings, exhibiting great concern for holiness. When dealing with the day-to-day Christian life, he focused most closely on four major points: union with Christ through the Spirit, the inseparable link of faith and the Word, the essentiality of repentance, and the Christian’s need for self-denial.
Union with Christ
In Calvin’s mind, there was no such thing as a “Christian life” apart from union with Christ. He posited that “until we become one with him, everything he possesses is nothing to us.” So how does one become united with Christ? Calvin explains: “The Holy Spirit is the bond by which Christ effectively binds us to himself. … By the grace and energy of the Spirit we become his members, so that he is in charge of us and we, in our turn, possess him.” In other words, the power of the Holy Spirit accomplishes this connection and applies salvation to the person. He also notes that in the gospel “we find the treasures of grace unfolded to us.” One becomes a believer by being united with Christ through the work of the Holy Spirit, and the gospel then discloses to them the fullness of Christ which is unknown without the Spirit.
The Connection of Faith and the Word
In the life of the Christian, Calvin saw faith and the Word of God as inseparable. He claimed that “they can no more be separated than rays of light from the sun.” He did not function as a wandering dreamer; he based faith itself on the objective truths of Scripture. To him, the authority held by Scripture is so transcendent, so otherworldly, that there is no way to have a markedly supernatural faith with a merely natural book.
Additionally, Calvin would make the case that “the Word is the base on which faith rests and is strengthened. … Take away the Word, and there will be no faith.” Faith was more than simple knowledge about God in the eyes of Calvin; he believed that faith was a knowledge of God’s revealed will in Scripture. The Word gives believers all that they need to grow in faith and to comprehend God’s will, and the denial of the truth of Scripture directly correlates to the weakening of faith. Through the power of the Spirit, holiness only came through direct relationship with knowing God's commands.
The Importance of Repentance
Calvin shifted to the primacy of repentance. Upon the believer’s union with Christ through the Spirit while their faith is being strengthened through the Word, the logical following result is repentance. He suggests that the gospel “is about repentance and forgiveness of sins. If these are omitted, any discussion about faith will be useless. … Repentance not only follows faith but is produced by it.” If the believer has been united with Christ and clothed in his righteousness, then he has been given a faith grounded in the authority of God’s Word. In turn, one must practice the ways of the new life by turning from the old life. If one truly understands God’s grace, then repentance is inevitable. As he put it, “a man cannot honestly say he knows about repentance unless he knows he belongs to God.”
Moreover, repentance is more plainly defined by Calvin as “a true conversion of our life to God, springing from real and solemn fear of God; it consists also in putting to death our flesh and the quickening of the Spirit.” First, people need a conversion of both the soul and their outward actions. Still walking in unrepentant sin, a person can hardly begin to seek righteousness through repentance in a meaningful way. Second, repentance springs from a sincere fear of God. The believer must truly come to grips with divine judgment and the reality of one day standing before God’s judgment seat. Lastly, repentance consists of mortification of the flesh and the Spirit’s imparting of holiness. Scripture is clear that believers must renounce the world and their own desires for the sake of Christ. The Holy Spirit, in turn, will “inspire our souls with new thoughts and affections.” The life of a Christian is entirely practical when weighed against Scripture. To Calvin, the Word is clear that God’s will is for his people to live a holy life and to use it in glorifying him.
In the end, no one who belongs to God will ever struggle so habitually that they do not still progress toward him daily. Salvation necessarily leads to holiness. Because of this, Calvin insists that Christians never give up on pursuing Christ.
The Act of Self-Denial
The definitive sum of the Christian life, according to Calvin, is self-denial. He concludes that “we must not follow our own way but the Lord’s will, and aim always to promote his glory. We are really succeeding when, almost forgetting ourselves and putting aside our own way of thinking, we genuinely try to obey God and his commandments.” The entirety of creation is God’s stage, and Christians are merely bit actors in his grand drama of redemption.
Not only so, but those united with Christ are members of his body, and thus they are members of one another. He is the head from which all of the functions of the body flows. As such, whatever one member of the body does, the rest of the body partakes of the action as well. All members exist for one another even as they all exist ultimately for Christ. All of this must be done selflessly as to avoid arrogance or moral blame. He expounds on this notion saying, “Really everyone should think that he owes himself to his neighbors, and that the only limit to his generosity is the end of his resources.”
Calvin’s emphasis on self-denial is rooted in Christ’s command to take up one’s cross and follow him. Just as the Father put his own Son through trials, he will certainly not spare the rest of his children. The more Christians share in Christ’s sufferings, the closer communion they experience with him, hence the further they progress in holiness.
A Theologian for Everyone
No person is perfect, and no one should agree with every single word a theologian says. But whether one resonates with Calvin’s theology as a whole or not, he is a theologian for everyone. He clearly loved Christ and wanted to point people to him. Ever the pursuer of God’s own heart, he has much to teach the world about lifting high the name of Jesus and living a life worthy of the calling (Eph. 4:1).
