As one poster replied in this thread - If this policy is too be enforced it needs to include those who obtained higher education prior to becoming one of Jehovah's Witnesses. Here is the argument for this:
Appointing a brother to the position of Elder or Ministerial Servant who obtained higher education prior to becoming one of Jehovah's Witness may still stumble someone in the congregation or send a conflicting message that pursuing higher education is acceptable by the organization.
All doctors and lawyers who are Witnesses should immediately be removed as Elders, Ministerial Servants, and any position of full time service in the organization.
