The Bible also gives us a sure test that we may know if an angel is from God:
"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God. (1 John 4:1-2)
“And I, Moroni, will not deny the Christ; wherefore, I wander whithersoever I can for the safety of mine own life.” (Moroni 1:3)
These words were written in about A.D. 420 as Moroni, one of the last living Nephites, fled the Lamanite armies. The record, which he delivered into the hands of Joseph Smith, was a witness that Jesus Christ is the Son of God, that he did come in the flesh and that through his atonement, all who come to him in obedience may be saved.
“Hereby know ye the Spirit of God.” According to John’s test, the visit of Moroni was of God.
Ah, but see, any person can write these words. You just did. And I just copied them. To use the Book of Mormon as evidence that the Book of Mormon is true is simply not enough of an answer to justify the truth of the book. You are going by the assumption that there was an angel named Moroni and that he did appear to a man and give him golden plates. My belief system is different - that the book was written with non-divine supernatural assitance.
To further address the issue of the Truth of the Book of Mormon. It is either what it says it is, or it is not. Joseph Smith was either a prophet, or he was not. There’s no way that Joseph Smith was not a prophet but the Book of Mormon was still true. To find evidence of truth, one has to start with what one can physically see, hear, touch, sense or smell. From natural evidence, supernatural faith can form a foundation.
Faith plays strongly into any religion - anyone who believes that a priest can whisper words over a piece of bread, and that bread becomes a man, and that Man is God, has to take a huge leap of faith and trust in a church founded over 2,000 years ago. However, somewhere in the formation of any religion there has to be historical evidence if not theological truth for there to at least be the foundations of belief for most people.
One of the main problems that many ex-Mormons have about the Book of Mormon is the complete lack of archeological evidence that the book existed. Whether you believe that Christ was who he claimed he was, there is still archeological evidence that there was a man named Jesus Christ, and he did die, and he suffered under Pontius Pilate, was crucified, died, and was buried. There is evidence of his early Church, and copies of ancient early manuscripts of the New Testament. But
there is none for the Book of Mormon - no
steel, no
horse bones (horses are mentioned fourteen times in the Book of Mormon), not one piece of verified evidence that this huge civilization that spanned hundreds of years ever existed.
