During 1955, Ernest Martin became a supporter of the ministry of Herbert W. Armstrong and the Radio Church of God (later known as the Worldwide Church of God). He attended Ambassador College at Pasadena, California, in 1958 and later transferred to the campus in Bricket Wood, England. He was ordained as a minister of the Radio Church of God in 1959 and continued with his studies at Ambassador College to finally earn an unaccredited Ph.D in education in 1966. From 1960 to 1972, he taught history, theology and elementary meteorology at the Ambassador College campus in Bricket Wood where he became Dean of Faculty.
In 1974, Martin wrote the first of five editions of The Tithing Dilemma�of which over 100,000 copies were sold. It was this work which triggered the first of many major schisms within the Worldwide Church of God.
