Philip Powell left the Australian Assemblies of God in 1992, believing that the church was preaching false doctrines and supporting false prophets and teachers. After his departure from the AOG, Powell became associated with others, who have come to similar conclusions. Philip with his wife, Kathleen launched Christian Witness Ministries in 1994, and began to publish a quarterly magazine entitled Contending EARNESTLY for THE Faith (CETF) out of Hamilton, New Zealand. There are now clearing offices in Australia and the UK as well as in New Zealand. The magazine is now published from Brisbane, Australia.
