I found the link to the sermon I was speaking of. It was recorded during last year's election when Mitt Romney was running. He explains these differences between Mormonism and Christianity far better than I could. You can listen to it if you wish.

Brother Obadiah, that was a good tape as far as I got and hope you don't mind I transcribed near as I could what was said there on the first part of it with minute markers shown I think others might find interesting.
The Mormon view of scripture.
6:24 Now the Mormons believe that the bible is a good book, and it's mostly accurate concerning the commandments of God, however through the years of being texted and copied, and people getting their hands on it the bible has many errors that have crept in it, so the bible therefore isn't in the Mormon view a perfect book. Lucky for us God revealed to the prophet Joseph Smith that there was a book that was buried in the ground that was written on gold plates in a different language by a group of native Americans who lived here in America around the time of Jesus. Now since these plates were original documents and not copies there is therefore no errors in them. Therefore these plates represent the perfect and uncorrupted word of God. These plates Joseph dug up from the ground were written in a different language that has been long since dead, so God gave Joseph Smith a Seer Stone and so he would put this stone in a hat, and he would bury his head into the hat and God would reveal the proper translation of these golden plates. These golden plates get translated into English for us and then become The Book of Mormon.
7:40 Now on the very front page in the introduction in the Book of Mormon this is what Joseph Smith said: “I told the brethren that the Book of Mormon was the most correct of any book on earth, and the keystone of our religion, and a man would get nearer to God by abiding by its precepts, than by any other book.â€
Number one. If the Book of Mormon is the most correct book on earth, what is not as correct? the Bible. If the Book of Mormon is the keystone to the Mormon religion, what book is not the keystone to the Mormon religion? the Bible.
8:36 And if "a man would get nearer to God by abiding by its precepts than by any other book.", this book is closer to God than what other book? the Bible, and this is written right on the very first page.
8:53 One of the non negotiable hallmarks of the Christian church is the superiority of the bible. All things are measured against the bible. The bible says this in 2 Timothy 3:16 that all scripture God breathed, and is inspired by God Himself and is useful for teaching, rebuking, correcting, and training in righteousness. So according to the bible, the bible is what gets you the closest to God. And now the Apostle Peter writes this (2 Peter 3:15-16): (NIV) "Bear in mind that our Lord’s patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him. 16 He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction."
