Most churches, and probably most Christians, assume that those who serve in the ministry, at least at the pastor level, should have seminary training.
There are some who dare to question this system. Their question is often, Are seminaries biblical? The answer they’re often given by seminary advocates is, Does something have to be biblical to be good? After all, cars, indoor plumbing, electricity, and other conveniences that we take for granted are not in the Bible. Even words such as “Trinity” are not in the Bible. But this response of citing general cases is an evasion of the question.
