"It's so hard to believe that these fine young men who come to my door talking about Jesus Christ aren't really talking about the Jesus Christ of the Bible." That's basically what many well-meaning, honest people think. They find it hard to believe that a couple of well-dressed, well-mannered young men could come to their homes and tell them about a false Jesus Christ. I myself once found that hard to believe, but as I studied the facts about Mormonism (and much of my study came from Mormon sources), I came to see that the Jesus Christ preached by Mormonism is not the Jesus Christ of the Bible, and is therefore incapable of saving anyone from anything.
So how can we know that the Jesus Christ of the Book of Mormon is not the same as the Jesus Christ of the Bible? Very simply. We can read both of them, and compare their personalities, lives and mission. For purposes of brevity, in this discussion we shall limit ourselves to examining their character, their prehistory, and their mission.
The Jesus Christ of Mormonism is a vengeful, angry person. In 3 Nephi 8-9, we see a prophecy of the signs of Christ's death that would be displayed in the Americas. We see such events as the destruction of whole cities, the drowning of thousands of people, and terrible destruction of the land northward. (Where this land is is another story. No one really knows.) Immediately after all of that happens, we hear the murderer proclaim his name: "I am Jesus Christ the son of God."
The Jesus Christ of the Bible is a loving, forgiving God. In all of the crucifixion accounts in the Gospels, no death or destruction is mentioned! Matthew mentions an earthquake. It must not have been a particularly strong one, since John doesn't even mention it at all. Certainly no one was killed. The Earth shook, and the stones rolled away from the tombs, so that some of the saints could rise again.
In fact, Matthew tells us that Jesus told those who arrested Him that He could have called down twelve legions of angels---but out of His mercy, He didn't. Does this sound like the action of a vengeful God? Or could you picture the Mormon Jesus, being repsonsible for millions of deaths in that short time span, crying out, "Father, forgive them: for they know not what they do!"
In the days before his first coming, the Mormon Jesus was known by name to the people of the Americas. Throughout their books prior to his first coming, the Mormon Jesus is called "Jesus Christ" with no explanation why they would know his first name, or why they would use the Greek word "Christ" instead of the Hebrew word "Messiah". It is also written that the people knew and followed Jesus Christ. Christians are called such hundreds of years before Christ.
In stark contrast to the above, the Bible has a different Old Testament approach to Jesus. In the Old Testament, Jesus is always referred to in the abstract; the Anointed One; the Branch; the Servant; my Lord. He is never referred to by name (this is, of course, conveniently "corrected" by Joseph Smith when he wrote his "Inspired Version"---as if man could EVER correct God's holy book!) . John alludes to this in John 1; in the beginning, He is known only as the Word. When the Word became flesh, He became known to the world as Jesus the Christ. In Acts 11:26, we are told that "the disciples were called Christians first in Antioch"---a few years after Christ's death, resurrection & ascension into heaven.
The mission of the Mormon Jesus seems to have been that of the Savior of the worthy, and a transitional prophet. The fact that (in Mormon fantasy) their Jesus Christ murdered millions of people who were sinners rather than helping them repent of their sin goes to show just what he thinks of sinners. Also the Mormon Jesus was something of a transitional prophet: he acted as a prophet to the people of the New World, but he was not the last original conveyor of God's words to the world. That office would later be taken over by the President of the LDS Church, the first of which was Joseph Smith.
In contrast, the Jesus Christ of the Bible came to save the SINNER, not the saved. "For GOD so loved the world that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life" (John 3:16). In this citation and MANY others, Christ proclaimed that He had come to save the LOST, the SINNERS, and not the righteous. The physician comes not to those who are well, but to those who are sick, Christ taught us. And the Christ of the Bible is not just another of God's many spokesmen: He is the Son of God, sent by God as THE LAST original proclaimer of God's Word (Hebrews 1:1-2).
Since the Mormon Jesus and the REAL Jesus are not one and the same, which will you follow?Even the Mormon will admit that there is no salvation outside of Jesus Christ. So the question becomes----which Jesus Christ?
