To the church of God which is at Corinth, to those who are sanctified in Christ Jesus, called to be saints, with all who in every place call on the name of Jesus Christ our Lord, both theirs and ours: (1 Corinthians 1:2, NKJV)
This salutation from Paul the apostle and brother Sosthenes gives us a number of insights into the character and purpose of local churches. First, the local church belongs to God, not to us. Culture and consensus do not legitimize rearranging the local church after our image. Next, each local church is identifiable and independent. This church was “at Corinth.” There is no hint of an overarching ecclesiastical and organizational oversight of this (or any other) local church. The centralization of authority over churches is unheard of in the New Testament. Scripture sufficiently organizes local churches to function and fulfill their God-given work. Next, the members of the local church are “sanctified in Christ Jesus” and thus, called “saints” (holy ones). Each Christian is a saint, purified from sins by the blood of Christ (Col. 1:20-22). As such, we are called to live holy lives before God and the world (Rom. 12:1). Finally, the Corinthians needed to know they were not alone. There were other saints “who in every place call on the name of Jesus Christ our Lord.” Christians still need the encouragement that comes from knowing others share common faith and fellowship with them in Christ our Lord (1 Cor. 1:9).
