Sectarianism, in the context of Christianity, refers to the division and separation within the body of Christ based on doctrinal differences, practices, or affiliations. The New Testament provides guidance on maintaining unity and avoiding divisions that can harm the witness of the Church and the spiritual growth of believers.

Biblical Foundation

The call to avoid sectarianism is rooted in the teachings of Jesus and the apostles. Jesus prayed for the unity of His followers, saying, "I have given them the glory You gave Me, so that they may be one as We are one" (John 17:22). This prayer underscores the importance of unity among believers as a reflection of the unity within the Godhead.

The Apostle Paul addresses the issue of divisions in the church at Corinth, urging believers to be united in mind and judgment: "I appeal to you, brothers, in the name of our Lord Jesus Christ, that all of you agree together, so that there may be no divisions among you and that you may be united in mind and conviction" (1 Corinthians 1:10). Paul emphasizes that allegiance should be to Christ alone, not to individual leaders or factions within the church.

Causes of Sectarianism

Sectarianism often arises from a variety of sources, including:

1. Doctrinal Disputes: Differences in interpretation of Scripture can lead to divisions. While doctrinal purity is important, it should not come at the expense of love and unity.

2. Personal Preferences: Preferences for certain styles of worship, leadership, or church governance can create factions. Paul warns against such divisions, reminding believers that "the kingdom of God is not a matter of eating and drinking, but of righteousness, peace, and joy in the Holy Spirit" (Romans 14:17).

3. Cultural and Social Differences: The early church faced challenges in integrating Jews and Gentiles. Paul addresses this by affirming that in Christ, "there is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus" (Galatians 3:28).

Biblical Responses to Sectarianism

1. Pursue Unity: Believers are called to "make every effort to keep the unity of the Spirit through the bond of peace" (Ephesians 4:3). This involves humility, patience, and bearing with one another in love.

2. Focus on the Essentials: While secondary issues may differ, the core tenets of the faith should unite believers. Paul reminds the Corinthians of the centrality of the gospel: "For I resolved to know nothing while I was with you except Jesus Christ and Him crucified" (1 Corinthians 2:2).

3. Practice Love and Forgiveness: Love is the hallmark of Christian discipleship. Jesus commands, "A new commandment I give you: Love one another. As I have loved you, so you also must love one another" (John 13:34). Forgiveness and reconciliation are essential in overcoming divisions.

4. Submit to Christ's Lordship: Recognizing Christ as the head of the Church helps believers maintain perspective. Paul writes, "He is the head of the body, the church; He is the beginning and firstborn from among the dead, so that in all things He may have preeminence" (Colossians 1:18).

Historical Context

Throughout church history, sectarianism has manifested in various forms, from early heresies to the denominational splits of the Reformation. While some divisions have been necessary to preserve doctrinal truth, others have been the result of human pride and misunderstanding. The challenge remains for the Church to discern when separation is necessary and when unity should be pursued.

Practical Application

In contemporary settings, avoiding sectarianism involves fostering dialogue and cooperation among different Christian traditions. Churches are encouraged to engage in ecumenical efforts that respect doctrinal differences while emphasizing shared beliefs and mission. Believers are called to prioritize the Great Commission and the Great Commandment, working together to advance the kingdom of God.
