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 Witness 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." Though Nee took the lead among the local churches in China, it was through one of his co-workers—Witness Lee —that the local churches spread worldwide. The two men first met in Lee's hometown of Yantai in 1932. Two years later, Lee moved to Shanghai to work with Nee. One of Lee's responsibilities there was the editing of some of Nee's publications. In the following years, Nee published many works and held regular conferences and trainings for church workers. Nee, Lee and other workers established over seven hundred local churches throughout China before the Communist Revolution resulted in the establishment of the People’s Republic of China in 1949. Near the end of the Communist Revolution, Nee sent Witness Lee to Taiwan to ensure that their work would survive the political turmoil. Developments after 1949 The Denunciation Movement that began in 1951 after China entered the Korean War aimed at severing Christian groups in China from foreign influence, including expelling all foreign missionaries. As a side effect of the disbanding of mission churches, the local churches experienced "a spectacular rise in membership." The Denunciation Movement turned to leading
