Apology

Not apology in the "I'm sorry" sense. Apology in the sense of the apologists, defending their faith.
Recently, I've come to have to defend my reasons for converting in different venues, at different times. I have yet to truly give my real reasons in complete explanation. So I will try to do so here. Please keep in mind, this is not my conversion story, not my Confessions, if you will. This is merely a defense against my previous religious beliefs and for my new ones.
A lot of the reasons why I don't believe in Mormonism are simple and sensible. I say sensible because I believe that the single biggest gift that God has given humankind is our intellect. This is truly the one thing that separates us from other animals, what makes us the "rational animal." I have seen this time and again in my theological studies when I read such men as Augustine, Origen, Jerome, Athanasius, Bonaventure, Anselm, Thomas Aquinas, and others have verified this fact. I have read the accounts of some of the greatest minds, read some of the greatest conversion stories and some of the most compelling arguments.
Then comes a 14 year-old farmboy who says that God has called him, and has told him that there are no correct Churches on the earth. 2000 years of the greatest thinkers and most devout believers are wrong. And then some farm boy is called to reveal the truth? Of course, as a Christian, I cannot dismiss the seemingly miniscule, as Christ comes from humble beginnings. But the wise men found him. The prophets of old weren't considered wrong. So why were the previous theologians dismissed?
Furthermore, there's the issue of scripture. So much of the Book of Mormon is derived from the Bible. Chapters from Isaiah are lifted straight from the source. Matthew 5-7 is also copied. There's not a lot of evidence for the peoples of the Book of Mormon. I don't see the resemblence between Native Americans and Jews. The timeline doesn't make sense to me either. Nor does the use of steel. Finally, I have problems with the Bible itself, which creates a multitude of problems for my beliefs in the Book of Mormon.
I guess if I were to sum it up, I find a lot of comfort in the intellectual tradition of the Roman Church. The Mormon Church does have its scholars, but theology is not something one can practice therein, nor is there any room for debate on doctrines.
