As soon as one talks about accreditation of theological education, people who have never been exposed to these things immediately conjure up images of centralization, one-man control, antichrist, etc. More so in churches that tend to be autonomous. This is because of a misunderstanding.
When we buy a product from a well known company, we expect it to deliver quality. That is why we shell out extra money, though a the same product might be available from a nondescript company. The well known company is able to offer quality product because of quality control. The same is the job of accreditation in theological education -- quality control.
