Our industry (HVAC) is the opposite. The self-taught seem to struggle with the newer technology.
IMHO one benefit of seminary is that it gives one the time to study and requires one to study outside of his own tradition. But probably the main benefit (not only of seminary but college in general) is the development of critical thinking skills.
Jon, I just have to post that I disagree.
First, the industries are suffering from the inexperienced employees, and especially the service industries, because more often the technical services teach from the bench and not from the field. Hands on training is always preferred when looking over applications.
Second, Imo, FEW undergraduate and graduate courses actually teach critical thinking skills. Most of them have the instructor presenting and the students have to document learning by restating the course work.
Here is the difficulty. The typical high school and lower system may engage some critical thinking, but the maturity level of the students and life experiences tend to limit the development much beyond beginner level. The undergraduate college/university level and even at the graduate level have typical 14 block class sessions. Far to short to develop much in the manner of thinking other then offer reading lists. The graduate level assumes the critical thinking has already been developed, and it is not necessary to spend time in that effort.
So, where is critical thinking learned?
The same place as that pastor who has had no "formal training." From the work environment in which the difficulties are real, and the demands are enormous.
At the industry level, it is the difference between a school trained tech and that tech seasoned first in the ranks of the apprentice. One will know theory, and have some bench knowledge, the other will have ears open listening to the mechanics, hearing the load and unloading mechanisms, putting hands on the equipment to sense levels of running temperatures, looking at the gauges for fluctuations...
Which one will diagnose and resolve the issues more quickly for the customer?
That field trained pastor may not have all the book knowledge of fine arts, of psychological methods, of accounting practices...
But, that family in crisis, will want someone who knows the ropes, and how to succeed because they have done the work, been in the trenches, and know how to handle the ship.
