Landmarkism, also called Baptist Bride theology, arose in the mid-nineteenth century among Southern Baptists as a reaction to liberalism. It was formalized in the 1851 Cotton Grove Resolutions and teaches that only properly constituted Baptist churches (defined by believer’s baptism by immersion, congregational polity, and historical succession) are true New Testament churches. Landmarkism holds that only such proper churches constitute the Bride of Christ, while other believers may be saved but remain outside that Bride.
Scripture, however, teaches that the church, while having local expressions, incorporates everyone united to Christ by faith. Believers are baptized by one Spirit into one body (1 Corinthians 12:13), Christ gave Himself for the church as a whole (Ephesians 5:25–27), and all who belong to Christ are fellow members of His body (Romans 12:5). By denying full standing to other genuine believers, Landmarkism promotes a sectarian division that Scripture condemns (1 Corinthians 1:12–13; Ephesians 4:4–6).
Landmarkism arose in the nineteenth century among Baptists who were concerned about doctrinal compromise and ecclesial looseness. In reaction to perceived liberalism and interdenominational cooperation, Landmark leaders argued that faithfulness to Christ required strict continuity with apostolic practice, especially regarding baptism, church polity, and local church authority. From this concern developed the conviction that only churches meeting specific Baptist distinctives could rightly be called New Testament churches.
Landmarkism concludes that non-Landmark Christians occupy a secondary standing because of how it defines the church. While most Landmark advocates affirm that salvation comes through faith in Christ, they sharply distinguish salvation from church membership and authority. Because they believe only Landmark Baptist churches possess valid baptism and proper ecclesial authority, they argue that believers outside those churches may be genuinely saved but are not part of a true New Testament church. From this, they reason that such believers cannot belong to the Bride of Christ, which they identify exclusively with properly constituted Landmark churches. Other Christians are therefore viewed as members of God’s kingdom or family, but excluded from full church standing and the privileges they associate with the Bride.
According to God’s Word, the church consists of everyone who has been united to Jesus Christ by faith. When a person repents of sin and trusts in Christ, God forgives them, gives them new life, and joins them to Christ by the Holy Spirit. From that moment on, they belong to Him and to His people. That union with Christ is what makes someone part of the church.
Local churches matter because they are how believers live out their faith together. They are places of teaching, fellowship, accountability, worship, and service. Christians are called to obey Christ within a local church and to pursue faithfulness and holiness there. Yet no single congregation defines the church on its own. Each local church is a visible expression of the single, unified body of Christ, which includes believers across cultures, nations, and generations.
Because of this, every believer stands on equal footing before God. There are no higher or lower classes of Christians and no partial membership or secondary tiers in Christ. All who belong to Christ belong fully to Him and fully to His church.
