大使命
The Great Commission Association of Churches (GCAC) is the current name of an Evangelical Christian association of churches that started as a movement in 1965, though not generally recognized as a movement until 1970. The movement at first avoided any denominational affiliation, becoming known in the early 1970s as "The Blitz" or "The Blitz Movement," then as Great Commission International (GCI) when leaders formed a formal organization in 1983. In 1989, GCI became GCAC ("Great Commission Association of Churches"), and Great Commission Ministries (GCM) was founded as the campus and international mission agency for GCAC; the campus ministry prior to this was known as Great Commission Students (GCS), although GCS did not employ full-time missionaries or do international work. Today, the "right hand of fellowship" ministry to international churches and ministries is known as the Great Commission Association (GCA). GCAC generally refers to itself as Great Commission Churches (GCC) in public communications.
