As far as I can tell, 1 Kings 18:4 is the best Scriptural warrant I can find for bible colleges (Americans read "Seminary"):
While Jezebel was killing off the LORD's prophets, Obadiah had taken a hundred prophets and hidden them in two caves, fifty in each, and had supplied them with food and water.
Away from all that troublesome ministry with its attendant persecution, the hidden prophets were fed and watered by Obadiah the first Principal of a Theological College. No doubt they spent their time fiercely debating the issues of credo-circumcision, the validity of women prophets and evidentialist apologetics to a post-Yahwistic mindset. I'm being playful of course (not with an endearing playfulness mind. More a sharp, abrasive playfulness, the kind of playfulness no one likes - that kind of playfulness.)
Anyway it must be admitted that bible college can be a breeding ground for all sorts of nonsense. But then we must take responsibility for how the college experience is enjoyed/handled/endured.
