I could not find very much information on Rev. John Poole. His father, Fred C. Poole, came from South Wales to pastor a church in Canada. Later he moved his family down to East Landsdowne Pennsylvania, USA and began pastoring a church called Philadelphia Gospel Temple.
In 1963, when his father died, Rev. John Poole began pastoring the church. Sometime after that he changed its name to Living Word Community. As far as I can tell, Rev. Poole pastored this church from 1963 to 1974 or 1975.
Below is an excellent series of messages on practical applications of the Book Of Revelation and an individual message. These were taken from old cassette tapes, but are very clear.
