What I know is that Primitive Baptists do not require, and in fact have strong distaste for, their ministers to be educated beyond the level of ability to just read the Bible and maybe say some study helps and classic Christian literature. I'd venture that is the near the same with Amish and Hutterites.
Probably most Mennonites, however, value more advanced education. There are associated Mennonite colleges and universities and a seminary. Some Mennonites are hardcore scholars with terminal degrees in a wide array of fields, and most of these combine their scholarship with ardent activism for their views.
For example, in a college class (at a "secular" honors college), Philosophies of Punishment, I focused closely on the views of a Mennonite author on
Restorative Justice,
Howard Zehr, and advocated in most instances for a restorative justice view up against alternate views in papers.
Zehr is a prof at Eastern Mennonite University. After I read his views, Zehr, basically the father of the whole modern restorative justice field, was very gracious to patiently let me,
a complete Christian stranger, pick his brain with some very hard questions by email for several weeks. He knew his stuff and was often uniquely insightful, although he did not in my view adequately allow for the adjudication of Hegelian "just deserts" to offenders Paul would define as
reprobate. But my point is that this helps show how Mennonites tend to much value higher education and often tie activism to their scholarship.
(Alas, I let you all know of another of my proclivities toward anabaptism).
Also, PB ministers are 100% "homegrown". They disdain the idea of bringing a new minister in from the outside, like a seminary grad. I'd venture that is the same or probably more so with Amish and Hutterites. Not sure how that works in Mennonite circles. Probably at least some allow non-homegrown folks to become ministers if the folks first get to know them a while.
Perhaps
Menno can add some thoughts here and clarify and/or correct mine where needed.
Danfrey, I agree completely with your statement on the gifts of the Spirit.
