Hulme is like almost all the other COG's out there. His group is small and insignificant even though it makes this claim that attempts to give the impression it is a huge church.
The Church of God, a nondenominational organization based in Pasadena, California, traces its antecedents to Sabbatarian communities in 17th-century Europe, and before that to the first-century apostolic Church at Jerusalem. Accordingly the Church endeavors to uphold the original practice and teachings of Jesus Christ and His followers. The Church of God has members all around the world and maintains offices in Australia, Germany, the Philippines, South Africa, Switzerland, the United Kingdom and the United States.
By their own admission they only have around 900 in the United states and about 600 internationally. I do have to appreciate the fact that Hulme has more members than Dave Pack does!
