If they taught you that in bible college you should get a lawyer and get your money back. Besides, you never did answer why you or any Protestants needed a bible college if the Bible is sufficiently self interpreting so as to not need a Magisterium.
Peace be with you
If they taught me what in Bible college??? What are you getting in a huff about this time?
As for why someone would want to study the faith in a formal institution and the connection to the Bible being "sufficiently self-interpreting", you need to ask yourself the same question and explain why priests, or even new members for that matter, need to be educated in the religion of Catholicism if the Magesterium is supposed to be the interpreter to everyone of what the rule of faith is. I hope you can see that the two are not mutually exclusive.
I am satisfied with the education I received at the Bible college but it was only the start of a life-long learning process of plumbing the depths of knowing God. It was, in a sense, a jump start in teaching me what I believed and why I believed it. Many Catholics, on the other hand, when asked why they believe a certain doctrine, can only answer with the feeble, "That's just what we believe.". When shown Scripture that contradicts what they are taught, many go into "turtle mode" and put their fingers in their ears, unable to deal with the truth and unwilling to explore further. Some, like myself, look into it and realize that God's word DOES have authority over what some religion states, and we choose to obey God rather than man. This, by the way, IS part of why we can know the Scriptures are God-breathed - the words have power to change hearts and draw souls out of false religions and into the light of the glorious gospel of the grace of God.
