Watchman Nee emphasizes the distinction between the universal Church and local churches, explaining that while the Church is one body, the apostles established separate churches based on locality. He clarifies that the term 'church' refers to the assembly of believers in a specific place, and that the division into local churches is divinely ordained to reflect the physical gathering of believers. Nee warns against the dangers of sectarianism and the importance of maintaining the local character of churches, asserting that each church should be independent yet spiritually connected to others. He concludes that the only scriptural basis for church division is geographical locality, and that true unity in Christ transcends physical boundaries.
