A bible college devotes a lot of time to convincing the student to accept the doctrines of the college - with the proof-texts to go along with them. That is why there are denominational Bible Colleges.
People think that they are qualified to be preachers and teachers when they complete the two-year curriculum as if they know "all truth." And THAT is the beginning of man's failure to depend on God to teach.
And then this practice and worse-- this mentality is what is taken out to the churches..... You get seminary trained 'preachers' who perpetuate the myths, misunderstandings and mistakes they were taught, which they then teach others as if their beliefs are unchallengeable facts. This is why scripture includes warnings for teachers--- for the damage they do.
