Nee's seminal works expounding his view of local churches—"The Assembly Life" and "Concerning Our Missions"—were written against the background of his experience with the Exclusive Brethren. Nee taught that there should only be one church in every city, that Christians should meet together simply as believers living in the same city regardless of differences in doctrine or practice. Nee believed that this would eliminate divisions between Christians and provide the broadest basis upon which all believers could meet. Both Nee and Lee emphasized the New Testament's references to churches by the name of the city (for example, in Acts, the Christians in Jerusalem being referred to as "the church which was at Jerusalem" (NKJV), as well as other verses with the same convention, including 1 Corinthians 1:2; Revelation 2:1, 8, 12, 18; 3:1, 7 and 14). Since Nee and Lee taught that there should only be one church in each city, and that that city was the extent of a church's jurisdiction, members of the local churches usually refer to their congregations as "the church in (city name)." According to Nee, this means that "the church in her locality must be inclusive, not exclusive,” that is, it “must include all the children of God in the whole spectrum of Christian faith and practice."
