Why did the COGIC split from AG church?

The proper question is why did the AG church split from COGIC? The founder of the Church Of God In Christ, Bishop Charles Harrison Mason ordained and commissioned three white men to begin ministering to other white members the message of holiness and the Holy Spirit. Because of the "Jim Crow" laws of the time many white did not feel comfortable worshipping with blacks. Bishop Mason gave the direction for these brothers in the faith to start ministering until came when we all could worship together as one body.
