Bishop G.A. Thompson is originally from Philadelphia, Pennsylvania. He holds a B.A. degree from the Moody Bible Institute (1971),a Th.M. degree from Boston University School of Theology (1975), and is a candidate for the DMin degree from the Gordon Conwell Theological Seminary.

He has been a senior pastor in Boston, MA since 1972 and now pastors Jubilee Christian Church, an inner-city church he and his wife started in 1982 that has grown to be one of the largest congregations in New England. He was consecrated to the apostolic office of bishop(September 29, 1999) when a presbytery of bishops and pastors from several Christian denominations gathered to anoint him.

He is the Presiding Prelate over the network of churches called - Church Without Walls International. The phrase: "A Church Without Walls" is the name of a vision God gave him in 1982 to transform inner cities - spiritually, economically, socially, educationally, politically, and culturally using the power of spiritual agreement and community collaboration.

Bishop Thompson has authored several books and teaching manuals on doctrine and foundational truth. He and his wife, Yvonne, have been married since February 1967, and have eight grown married children, and as of 2010, twenty-one (21) grandchildren. (Of course, since the family is still growing, the last number should be checked for accuracy).
