The World Mission Society Church of God is a new religious movement that originated in South Korea in 1964. After founder Ahn Sahng-hong died in 1985, the Church expanded its activities to other parts of the world and began to use the name World Mission Society Church of God.
The church was founded in South Korea on April 28, 1964 by Ahn Sahng-hong, and its name is the Church of God Jesus Witnesses. After Ahn Sahng-hong died in February 1985, a group of people in Church of God Jesus Witnesses including the man Kim Joo-cheol[a] and the woman Zahng Gil-jah wanted to re-introduce the concept of a "spiritual mother", and on 22 March 1985 moved from Busan to Seoul.[5][6][7] On a meeting in Seoul on 2 June 1985, they discussed how to call Zahng Gil-jah,[8] and established a church called Witnesses of Ahn Sahng-hong Church of God. Two major new doctrines were codified[9][10]
