According to "Time" in a 1982 article, the church soon obtained the resignation of 120 clergy and teachers who refused to support SDA teachings. This was presumably for their support of Ford's theology. Peter Ballis, professor of sociology at Monash University and an ex-pastor himself, wrote the definitive study on the subject, "Leaving the Adventist Ministry", which grew out of his doctoral studies. He found that 180 pastors left the Adventist ministry in Australia and New Zealand over the succeeding 8 years and calls it "the most rapid and massive exit of Adventist pastors in the movement’s 150-year history" (although he cautions that the fallout may have involved more than one factor). He claims the primary reason for exiting was not theology or personal reasons, but treatment by administrators. It is further speculated by Ford that a number of current ministers privately agree with Ford but refrain from speaking publicly on the issue for fear of losing their employment. Some in the Adventist church feel that the events of 1980 represent a major milestone in the theological development of the church, and that the effects of this controversy continue to be felt today.
