This question often elicits two extreme responses: some judge the Reformation as damaging unity, while others see it as God’s work to purify the church. To be fair, we need to ask: does the Bible demand absolute uniformity, or unity rooted in the Gospel? The Bible’s answer helps us evaluate the Reformation clearly, while also guiding our hearts to build true unity today.
Reading the Question Fairly: The Reformation as a Movement of Purification
The Reformation in the 16th century arose from a longing to return to the Gospel and the authority of the Word. Amid practices and teachings considered to have gone astray, the Reformation called for repentance and renewal. Was the result merely “division”? It is not that simple. In biblical history, God often uses prophetic correction to restore His people. Purification sometimes feels like division, but its spiritual goal is faithfulness to the truth. When the truth of the Gospel is restored, the doors to spiritual growth and mission reopen.
What the Bible Teaches About Unity
Jesus prayed that His disciples “may be one” (John 17:21). Paul advised the church to maintain the unity of the Spirit in peace and to remember that there is “one body, one Spirit, one Lord, one faith, one baptism” (Ephesians 4:3-6). On the other hand, the Bible also warns that there should be no divisions among you, but that you should be of one mind in Christ (1 Corinthians 1:10). From this, we learn that the unity God desires is not a compromise of the Gospel, but a unity born from the truth of the Gospel. Unity without the Gospel is merely empty uniformity. Truth without love produces hardness of heart. The Bible calls us to hold both.
Why Differences Occur: Core Doctrines and Debatable Matters
Some differences arise because believers try to obey the Word in different contexts and languages. What is important is to distinguish between essential doctrines and debatable matters. Core doctrines include the person and work of Christ, salvation by grace through faith, and the authority of Scripture. In this realm, the Apostle Paul sternly rebuked when the Gospel was distorted, such as when he confronted Peter for the truth of the Gospel (Galatians 2:11-14).
However, there are also matters that are debatable, where the congregation is encouraged to accept one another and not judge, while still guarding conscience and love (Romans 14:1-6). When differences touch on non-essential areas, the Bible encourages humility, dialogue, and love. With healthy discernment, differences do not have to lead to hostility.
Good Fruits and Real Wounds from the Reformation
We must be honest: the Reformation produced precious spiritual fruits as well as real historical wounds. Among its fruits was the reaffirmation of salvation by grace and the authority of the Word in the language of the congregation, making the Bible more accessible. The emphasis on evangelism, education, and congregational music also grew stronger. On the other hand, denominational fragmentation caused prejudice and wounds among believers, even social conflicts in some places. The Bible acknowledges this reality of tension and invites the church to repent from spiritual pride, while persevering in maintaining unity in truth.
Interestingly, the council in Jerusalem shows a healthy pattern when the church faces serious differences. The apostles and elders deliberated, listened to testimonies, weighed the Scriptures, then concluded, “it seemed good to the Holy Spirit and to us” (Acts 15:28). This model affirms that unity is built through prayer, the Word, and a willingness to listen.
How We Build Biblical Unity Today
First, return to the center of the Gospel. The core of unity is not the name of a denomination, but Jesus Christ crucified and risen. When the Gospel is the center of worship, teaching, and ministry, diverse churches can walk in harmony.
Second, humbly distinguish between essentials and non-essentials. Hold firmly to the core, be gracious about disputable matters, and let love characterize everything (1 Corinthians 13:1-7). Faithfulness to the truth does not eliminate gentleness.
Third, practice holy dialogue. Listen before judging. Test everything with Scripture. If correction is needed, do it gently, “making every effort to keep the unity of the Spirit” (Ephesians 4:3). Cross-tradition prayer centered on Christ has the power to heal old wounds.
Fourth, witness together before the world. Jesus’ prayer links church unity with the world’s testimony, “so that the world may believe” (John 17:21). Joint mission often brings together hearts that were previously distant. When the church serves the vulnerable, faithfully teaches the Word, and lives out Christ’s love, secondary differences lose their significance.
Conclusion
Does the Reformation cause Christianity to be divided? The Reformation brought about more visible differences, but it also restored many essential aspects of the Gospel. When approached with a heart submissive to the Word, differences do not have to mean hostility. Biblical unity is unity in truth and love. Therefore, let us pursue unity that is born from the knowledge of Christ, maintain peace, and together bear witness to the world that Jesus is alive. This is the unity that answers the prayer of our Lord.
