Ahah,
Perhaps it would be insightful to consider when you were going to school as a metaphore. All of your teachers from kindergarten to senior in highschool had to have a "degree" to teach. Each came into your life at a time when a previous teacher had prepared you for what came next. As you changed, your need for a different education changed. Was Mrs. White who you loved in third grade "better than" Mr. Snodgrass in fourth grade?
Of course not. You may have liked the nappys in the afternoon and wish it were still that way, but by forth grade you got another outside recess or learned a different team sport rather than napping.
Your algebra teacher in 8th grade isn't better or worse in terms of qualifications. You are different and the school board knows that once you have completed a series of courses in math, algebra comes next. Even though you though Mrs. Pennywinkle was the only one you would ever learn from, life deals a different reality. Calculus and foreign language are eventually in the cards.
As to the exclusivist scriptures in the Bible indicating there is only one way to learn "reach the father" it is true. Recall Jesus said, "when I am in the world, I am the light of the world". Certainly there was no other way to reach the father at the time of Jesus than through the "annointed one, Christ". That this is taken by Christians to mean for the entire globe and for all time is, IMHO, an unrealistic rendering. What are the "fruits" of such a doctrin? The feeling and exposition of superiority, untold inhumanity to mankind by the Christian church down though history. Were I asked to test the fruits of exclusivity in any relgion, I would have to say it is found wanting.
Hope this makes sense.
