🏛️ Third Quarter 2026: 1 and 2 Corinthians
After addressing the factions and struggles for power in the opening chapters, Paul now turns to an even deeper problem. The church in Corinth not only struggled with pride, rivalry, and spiritual immaturity; the moral standards of the surrounding culture had also entered the life of the church. The fourth lesson therefore addresses very specific issues: open sexual immorality, the church’s response to serious sin, lawsuits among Christians, the significance of the body as the temple of the Holy Spirit, and marriage and singleness. At the center stands a fundamental question: How can a church remain faithful to God’s truth, love people, and work toward restoration at the same time?
💎 Memory Verse
“What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body.”
1 Corinthians 6:19–20
Paul directly connects sanctification with our identity. For him, the body is neither insignificant nor an area about which faith has nothing to say. Those who belong to Christ belong to Him with their entire lives. The Holy Spirit does not dwell only in our thoughts or religious convictions, but lays claim to the whole person. The way we approach sexuality, health, relationships, and physical needs therefore also possesses a spiritual dimension.
This statement leads us away from two extremes. On the one hand, the body is not an idol whose every desire must be obeyed; on the other hand, it is not a worthless vessel that may be treated carelessly. It belongs to God because Christ has redeemed us.
🧭 What Is This Lesson About?
Paul is shocked by a case of sexual immorality in Corinth that was considered scandalous even within the pagan society surrounding the church. A church member was living in a relationship with his father’s wife, apparently his stepmother. Even more disturbing to Paul, however, was the church’s reaction. Instead of grieving over this situation and correcting it, the members appeared to boast about their tolerance. Paul therefore sees not only the sin of one individual, but a deeper crisis affecting the entire community.
This reveals how easily concepts such as love, freedom, and tolerance can be misunderstood. Biblical love does not mean approving everything a person does. Precisely because people are valuable, God also takes seriously whatever destroys them. Paul therefore calls for a clear response from the church, but his goal is not destruction, public humiliation, or permanent exclusion. Church discipline should lead to recognition of sin and ultimately to restoration. The lesson even suggests that the repentant person later mentioned in 2 Corinthians 2 may have been the same man whom Paul had previously called to repentance.
This creates a tension that Christian churches must still face today: How can we take sin seriously without abandoning the sinner? How can we demonstrate love without turning truth into indifference?
📖 The Lesson at a Glance
Paul begins 1 Corinthians 5 by addressing the painful discrepancy between the church’s profession of faith and its way of life. The Corinthians called themselves Christians, yet something that clearly contradicted God’s Word was openly tolerated among them. Paul regards this as particularly dangerous because a church can thereby lose its spiritual identity. It exists within a culture, but must not simply adopt that culture’s standards. This problem forms the background of the entire lesson: the values of Corinth had begun to shape the values of the church.
Paul therefore responds with clear words. The man concerned is to be removed from the fellowship as long as he deliberately persists in his way of life. Such statements may sound harsh, but Paul does not understand church discipline as revenge. The goal remains the person’s salvation. Those who deliberately turn away from God’s will must be helped to recognize the consequences of their path and come to repentance. Church discipline is not necessarily the opposite of love. When it serves to protect the church and restore the person concerned, it can be an expression of responsible love.
It is equally important to recognize what Paul does not require. He does not demand that Christians end all contact with people outside the church who do not live according to Christian standards. That would be incompatible with mission. His concern is directed toward people who openly profess Christ while stubbornly continuing in a way of life that contradicts that profession. Paul thereby makes it clear that higher standards are applied to Christians not because they are better people, but because their lives should reveal to whom they belong.
In 1 Corinthians 6, Paul addresses another problem: church members were taking one another to court. According to the lesson, this does not refer to serious crimes that clearly fall under the jurisdiction of the civil authorities, but apparently to internal civil disputes. Paul finds it shameful that Christians are incapable of resolving such conflicts with one another in a Christlike manner. In Roman society, status and social position could influence legal judgments; the church, by contrast, was meant to be a community in which justice, humility, and reconciliation became visible.
Paul then leads the Corinthians to a decisive principle: Christian freedom does not mean freedom to sin. Some in Corinth appear to have understood the message of the gospel to mean that a person was now free to do anything. Paul firmly rejects this idea. Christ did not free us from sin so that we might then choose to serve it voluntarily. Freedom in the gospel means freedom from the dominion of sin and freedom for a life with God.
This is especially important to Paul in the area of sexuality. The body does not simply belong to us. It is “for the Lord,” we are members of Christ, and our bodies are temples of the Holy Spirit. These three statements connect identity with conduct. Who we are in Christ cannot be permanently separated from the way we live. Paul therefore calls not merely for greater self-control, but for a deeper relationship with Christ. Sanctification does not begin with moral pressure, but with belonging: I belong to Christ; therefore, I desire to live in a way that reflects Him.
In this context, Paul then addresses marriage and singleness. He does not write about relationships in the abstract, but responds to specific questions from the church. It becomes clear that, according to the biblical understanding, sexuality is neither something dirty nor something arbitrary. It belongs within the marriage established by God and is to be experienced there with mutual responsibility and respect. At the same time, an unmarried life also possesses dignity and spiritual value. What ultimately matters is not a person’s marital status, but whether that person places his or her life at Christ’s disposal.
🔎 A Deeper Thought
Truth and Love Must Not Be Set Against Each Other
The church in Corinth appears to have made a mistake that seems remarkably modern. It apparently regarded tolerance as a sign of spiritual maturity without recognizing that it was normalizing something capable of destroying both individuals and the community. Paul, by contrast, shows that love does not consist of affirming every decision a person makes.
The opposite extreme would be equally wrong. Truth without love can become harsh, self-righteous, and destructive. Those who merely point out faults, shame people, or hastily write them off are not acting in the spirit of Christ either. Paul therefore combines clarity with the goal of restoration. Sin must be named, but the sinner should be won back.
Second Corinthians 2 reveals this other side especially clearly. When a person has repented, the church should not continue burying him beneath his past. It is then time to forgive, comfort, and receive him again. Church discipline fulfills its purpose not when someone remains permanently excluded, but when repentance becomes possible and fellowship can be restored.
This produces a carefully balanced biblical picture: grace does not make sin harmless, and truth does not make grace unnecessary. The two meet in Christ.
🔗 The Bible Explains the Bible
First Thessalonians 4:1–8 explicitly connects sanctification with sexual conduct. Paul reminds believers that God’s will is their sanctification. Christian sexual ethics therefore does not arise from cultural prudishness, but from the conviction that human beings belong to God and that their lives stand under His authority.
Romans 12:1 expands upon the idea of the temple of the Holy Spirit. Paul urges Christians to present their bodies as living sacrifices, holy and acceptable to God. Worship therefore does not take place only on the Sabbath or during a church service. Sleep, nutrition, sexuality, work, relationships, and the way we treat our bodies can all become expressions of our dedication to God.
Galatians 5:13 finally expands upon the subject of freedom. Paul explains that Christians have been called to freedom but must not use that freedom as an opportunity for selfish desires. True freedom is revealed in serving one another through love. This shows that Christian freedom can never be understood independently of Christ.
💬 Questions for Reflection
Where is the boundary between Christian love and false tolerance? Love does not ask only whether a person feels accepted at the present moment, but also where that person’s path is leading. Love may therefore sometimes encourage and comfort, but at other times warn and correct. What matters is that both responses arise from a desire for salvation and restoration.
Why is it dangerous when the standards of the surrounding culture enter the church unnoticed? Because Christians can grow accustomed to things they once recognized as harmful. Culture shapes our thinking more powerfully than we often realize. The church therefore needs continually to compare its beliefs and practices with God’s Word and remain willing to accept correction even where society has long established different standards. The study guide explicitly identifies this danger as one of the week’s central questions.
What does it mean in practical terms that our bodies are temples of the Holy Spirit? It means that our physical lives cannot be separated from our spiritual lives. The way we treat our bodies, the relationships we enter, the desires to which we give room, and the way we use God’s gifts in creation all belong to our discipleship.
How should a church respond to someone who sincerely repents after a serious failure? That person’s past must not become his or her lifelong identity. In 2 Corinthians 2, Paul calls for forgiveness, comfort, and renewed acceptance. A church that calls people to repentance must therefore also be willing to recognize genuine repentance and make grace tangible.
🌱 Understand – Deepen – Live
Understand in this lesson means first recognizing that grace and holiness are not opposites. God accepts sinners, but He does not simply leave them unchanged. The gospel not only forgives guilt, but also calls people into a new life. Paul can therefore remind the Corinthians that some of them had once been trapped in the very ways of life he now condemns and then add that they had been washed, sanctified, and justified. The past does not have to remain the future.
Deepen means reflecting anew upon the statement, “You are not your own.” In a culture in which personal autonomy is often regarded as the highest value, these words may sound unfamiliar. For Paul, however, they are not a threat, but good news. We no longer belong to sin, our desires, or destructive habits. We belong to the Christ who “bought us with a price.” It is precisely this belonging that makes true freedom possible.
Live ultimately means refusing to restrict the presence of the Holy Spirit to religious moments. If our bodies are His temples, God must be permitted to speak into every area of our lives. Sanctification then becomes not a catalog of outward rules, but a daily question: How can what I do today with my body, relationships, thoughts, and decisions demonstrate that I belong to Christ?
📜 Ellen White on the Subject
For further study, Friday’s lesson refers to Ellen White’s chapter “A Message of Warning and Entreaty” in The Acts of the Apostles, as well as to statements concerning sanctification and self-control. She explicitly connects spiritual sanctification with the whole person and warns against regarding physical habits, desires, and passions as areas separate from spiritual life.
One especially important thought is that the Holy Spirit gains room where a person becomes willing to surrender self and abandon false attachments. Sanctification therefore does not consist merely of avoiding certain outward behaviors. It is the result of a life that is increasingly filled with Christ. The more deeply Christ shapes the heart, the more profoundly a person’s relationship with the body, desires, relationships, and habits is also transformed.
Ellen White thus reinforces the central emphasis of the memory verse: the body does not become a holy temple through human willpower alone, but because the Holy Spirit is truly permitted to dwell and work within us.
✨ The Thought for This Sabbath
The fourth lesson is uncomfortable because it reminds us that the gospel does not only comfort, but also corrects. Christ does not merely desire to possess one religious area of our lives while every other area follows our own standards. He lays claim to the whole person.
Yet there is something liberating precisely in this truth. Paul does not say to the Corinthians, “You must improve yourselves so that God might perhaps accept you.” He first reminds them who they have already become through Christ: washed, sanctified, justified, and bought with a price. A new life grows out of this new identity.
Sanctification therefore does not begin with the desperate question, “How can I finally become good enough?” It begins with the realization: I belong to Christ.
When this truth sinks more deeply into the heart, it also changes the way we deal with sin. We need neither minimize it nor despair because of it. Christ can forgive, cleanse, and restore. At the same time, His grace calls us out of ways of life that contradict His love.
The church also needs this balance. It must not become so tolerant that sin appears insignificant, nor so harsh that repentance no longer provides a way back. It should be a place where truth is spoken, grace is experienced, and transformation becomes possible.
“You were bought with a price” is therefore both an assurance and a commission. Our lives possess immeasurable value because Christ paid the price for them—and for that very reason, we may demonstrate with our entire lives to whom we belong.
