Beyond what has already been mentioned here,I want to point out that the Society bears a heavy responsibility to the many who have been harmed by this unscriptural teaching.
The field service is a standard by which the Society uses to measure the spirituality of others in the Congregation.Their love of God,is also measured by the amount of field service they do.
Appointments to priviledges are based on the field service.Most important is the damage done to those who believe that this preaching is biblically taught and advocated.Damage such as separation from loved ones because of going to prison rather than stop preaching when told to by the authorities.
Some have even died when preaching in different parts of the earth,including the U.S.A.
So, it is more than a scam,it is a doctrine that has caused more harm than good.
