(1) The Book of Mormon teaches that little children are not capable of sin because they do not have a sinful nature (Moroni 8:8). In contrast, the Bible in Psalm 51:5 clearly teaches that we have a sinful nature from birth. (This does not mean that those who die in infancy are lost.)

Moroni 8:8
"Listen to the words of Christ, your Redeemer, your Lord and your God. Behold, I came into the world not to call the righteous but sinners to repentance; the whole need no physician, but they that are sick; wherefore, little children are whole, for they are not capable of committing sin; wherefore the curse of Adam is taken from them in me, that it hath no power over them; and the law of circumcision is done away in me."

But the Bible says:

Psalm 51:5 (KJV)
"Behold, I was shapen in iniquity; and in sin did my mother conceive me."

(2) The Book of Mormon teaches that the disobedience of Adam and Eve in eating the forbidden fruit was necessary so that they could have children and bring joy to mankind (2 Nephi 2:23-25). In contrast, the Bible specifically declares that Adam's transgression was a sinful act of rebellion that unleashed the power of sin and death in God's perfect world (Romans 5:12; 8:20-21). There is no Biblical support for the view that Adam and Eve could only fulfill the command to "be fruitful and multiply" (Genesis 1:28) by disobeying God's command regarding the forbidden fruit (Genesis 2:17). The Book of Mormon teaching that these divine commands are contradictory, and that God expected Adam and Eve to figure out that in reality He wanted them to break the latter command ("of the tree of the knowledge of good and evil, thou shalt not eat of it") in order to keep the former ("be fruitful and multiply"), has no basis in logic or the Biblical text, and attributes equivocation to God.

2 Nephi 2:22-25
22 And now, behold, if Adam had not transgressed he would not have fallen, but he would have remained in the garden of Eden. And all things which were created must have remained in the same state in which they were after they were created; and they must have remained forever, and had no end. 23 And they would have had no children; wherefore they would have remained in a state of innocence, having no joy, for they knew no misery; doing no good, for they knew no sin. 24 But behold, all things have been done in the wisdom of him who knoweth all things. 25 Adam fell that men might be; and men are, that they might have joy.

But the Bible says:

Romans 5:12 (KJV)
"Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned"

Romans 8:20-21 (KJV)
20 For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope, 21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.

Genesis 1:28 (KJV)
"And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth."

Genesis 2:17 (KJV)
"But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die."

(3) The Book of Mormon teaches that black skin is a sign of God's curse, so that white-skinned people are considered morally and spiritually superior to black-skinned people (2 Nephi 5:21). In contrast, the Bible teaches that God "made of one blood all nations of men" (Acts 17:26), that in Christ distinctions of ethnicity, gender and social class are erased (Galatians 3:28), and that God condemns favoritism (James 2:9).

2 Nephi 5:21
"And he had caused the cursing to come upon them, yea, even a sore cursing, because of their iniquity. For behold, they had hardened their hearts against him, that they had become like unto a flint; wherefore, as they were white, and exceedingly fair and delightsome, that they might not be enticing unto my people the Lord God did cause a skin of blackness to come upon them."

But the Bible says:

Acts 17:26 (KJV)
"And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation"

Galatians 3:28 (KJV)
"There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus."

James 2:9 (KJV)
"But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors."

(4) The Book of Mormon teaches that, "it is by grace that we are saved, after all we can do" (2 Nephi 25:23; see also Moroni 10:32). In contrast, the Bible teaches that apart from Christ we are dead in sin (Ephesians 2:4-5) and unable to do anything to merit forgiveness and eternal life. Salvation is wholly of grace (Ephesians 2:8-9; Romans 11:6; Titus 3:5-6), not by grace plus works. Good works are a result, not the basis, of a right relationship with God (Ephesians 2:10).

2 Nephi 25:23
"For we labor diligently to write, to persuade our children, and also our brethren, to believe in Christ, and to be reconciled to God; for we know that it is by grace that we are saved, after all we can do."

Moroni 10:32
"Yea, come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; and if ye shall deny yourselves of all ungodliness and love God with all your might, mind and strength, then is his grace sufficient for you, that by his grace ye may be perfect in Christ; and if by the grace of God ye are perfect in Christ, ye can in nowise deny the power of God."

But the Bible says:

Romans 11:6 (KJV)
"And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work."

Ephesians 2:4-5 (KJV)
4 But God, who is rich in mercy, for his great love wherewith he loved us, 5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)

Ephesians 2:8-10 (KJV)
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast. 10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.

Titus 3:4-6 (KJV)
4 But after that the kindness and love of God our Saviour toward man appeared, 5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; 6 Which he shed on us abundantly through Jesus Christ our Saviour

(5) According to the Book of Mormon, about 600 years before Christ, a Nephite prophet predicted that "many plain and precious parts" (1 Nephi 13:26-28) would be removed from the Bible. In contrast, from the Bible it is clear that during His earthly ministry, Jesus Himself constantly quoted from the Old Testament Scriptures, and showed full confidence in their completeness and accurate transmission as they had survived down to His time. Jesus declared that "heaven and earth shall pass away, but My words shall not pass away" (Mark 13:31; see also Matthew 5:18), and promised His disciples who were to pen the New Testament that the Holy Ghost "shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you" (John 14:26); Jesus further promised the apostles that they would "bring forth fruit, and that your fruit should remain" (John 15:16). These promises clearly imply that the fruit of the apostles - the New Testament Scriptures and the Christian church - would endure.

1 Nephi 13:26-28
26 And after they go forth by the hand of the twelve apostles of the Lamb, from the Jews unto the Gentiles, thou seest the formation of a great and abominable church, which is most abominable above all other churches; for behold, they have taken away from the gospel of the Lamb many parts which are plain and most precious; and also many covenants of the Lord have they taken away. 27 And all this have they done that they might pervert the right ways of the Lord, that they might blind the eyes and harden the hearts of the children of men. 28 Wherefore, thou seest that after the book hath gone forth through the hands of the great and abominable church, that there are many plain and precious things taken away from the book, which is the book of the Lamb of God.

But the Bible says:

Mark 13:31 (KJV)
"Heaven and earth shall pass away: but my words shall not pass away."

Matthew 5:18 (KJV)
"For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled."

John 14:26 (KJV)
"But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."

John 15:16 (KJV)
"Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you."

(6) According to a Book of Mormon prophecy (Helaman 14:27), at the time of Christ's crucifixion "darkness should cover the face of the whole earth for the space of three days." In contrast, the New Testament gospel accounts declare repeatedly that there was darkness for only three hours while Jesus was on the cross (Matthew 27:45; Mark 15:33; Luke 23:44).

Helaman 14:27
"And he said unto me that while the thunder and the lightning lasted, and the tempest, that these things should be, and that darkness should cover the face of the whole earth for the space of three days."

But the Bible says:

Matthew 27:45 (KJV)
"Now from the sixth hour there was darkness over all the land unto the ninth hour."

Mark 15:33 (KJV)
"And when the sixth hour was come, there was darkness over the whole land until the ninth hour."

Luke 23:44 (KJV)
"And it was about the sixth hour, and there was a darkness over all the earth until the ninth hour."

(7) The Book of Mormon teaches that there were many high priests serving at the same time (Mosiah 11:11; Alma 13:9-10; 46:6,38; Helaman 3:25) among the Book of Mormon people who are described as Jewish immigrants from ancient Israel who "kept the law of Moses" (e.g., 2 Nephi 25:10; Jacob 4:5; Jarom 1:5). In contrast, it is clear from the Bible that only one individual at a time occupied the office of high priest under the Old Testament dispensation (see, for example Leviticus 21:10; Matthew 26:3; Hebrews 8:6-7). (The mention in Luke 3:2 of "Annas and Caiaphas being the high priests" is not a real exception - in Christ's time Israel was under the domination of the Romans, who intervened to change the high priest at will. See John 18:13, which describes Annas as "father-in-law to Caiaphas, which was the high priest that same year.")

Mosiah 11:11
"And the seats which were set apart for the high priests, which were above all the other seats, he did ornament with pure gold; and he caused a breastwork to be built before them, that they might rest their bodies and their arms upon while they should speak lying and vain words to his people."

Alma 13:9-10
9 Thus they become high priests forever, after the order of the Son, the Only Begotten of the Father, who is without beginning of days or end of years, who is full of grace, equity, and truth. And thus it is. Amen. 10 Now, as I said concerning the holy order, or this high priesthood, there were many who were ordained and became high priests of God; and it was on account of their exceeding faith and repentance, and their righteousness before God, they choosing to repent and work righteousness rather than to perish

Alma 46:6,38
6 Thus they were led away by Amalickiah to dissensions, notwithstanding the preaching of Helaman and his brethren, yea, notwithstanding their exceedingly great care over the church, for they were high priests over the church. 38 And Helaman and the high priests did also maintain order in the church; yea, even for the space of four years did they have much peace and rejoicing in the church.

Helaman 3:25
"And so great was the prosperity of the church, and so many the blessings which were poured out upon the people, that even the high priests and the teachers were themselves astonished beyond measure."

2 Nephi 25:10
"Wherefore, it hath been told them concerning the destruction which should come upon them, immediately after my father left Jerusalem; nevertheless, they hardened their hearts; and according to my prophecy they have been destroyed, save it be those which are carried away captive into Babylon."

Jacob 4:5
"Behold, they believed in Christ and worshiped the Father in his name, and also we worship the Father in his name. And for this intent we keep the law of Moses, it pointing our souls to him; and for this cause it is sanctified unto us for righteousness, even as it was accounted unto Abraham in the wilderness to be obedient unto the commands of God in offering up his son Isaac, which is a similitude of God and his Only Begotten Son."

Jarom 1:5
"And now, behold, two hundred years had passed away, and the people of Nephi had waxed strong in the land. They observed to keep the law of Moses and the sabbath day holy unto the Lord. And they profaned not; neither did they blaspheme. And the laws of the land were exceedingly strict."

But the Bible says:

Leviticus 21:10 (KJV)
"And he that is the high priest among his brethren, upon whose head the anointing oil was poured, and that is consecrated to put on the garments, shall not uncover his head, nor rend his clothes"

Matthew 26:3 (KJV)
"Then assembled together the chief priests, and the scribes, and the elders of the people, unto the palace of the high priest, who was called Caiaphas,"

Hebrews 8:6-7 (KJV)
6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises. 7 For if that first covenant had been faultless, then should no place have been sought for the second.

(8) The Mormon's use of Ezekiel 37:16-17 as Biblical justification for the Book of Mormon

Ezekiel 37:16-17 (KJV)
16 Moreover, thou son of man, take thee one stick, and write upon it, For Judah, and for the children of Israel his companions: then take another stick, and write upon it, For Joseph, the stick of Ephraim and for all the house of Israel his companions: 17 And join them one to another into one stick; and they shall become one in thine hand.

Mormon interpretation:

Since a stick may have been used in ancient times to support a scroll of parchment, the stick of Judah is the Bible, the written record of the Jews. The stick of Joseph must, then, refer to another sacred book; the Book of Mormon, the record of Joseph's descendants who migrated to the Americas.

Biblical context:

In the following verses Ezekiel records God's own explanation of what is really meant by the two sticks:

Ezekiel 37:18-22 (KJV)
18 And when the children of thy people shall speak unto thee, saying, Wilt thou not shew us what thou meanest by these? 19 Say unto them, Thus saith the Lord GOD; Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, even with the stick of Judah, and make them one stick, and they shall be one in mine hand. 20 And the sticks whereon thou writest shall be in thine hand before their eyes. 21 And say unto them, Thus saith the Lord GOD; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land: 22 And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all.

The meaning of the two sticks is plainly explained here in the same chapter of Ezekiel, and it has nothing to do with the Book of Mormon. When the twelve tribes of Israel escaped from bondage in Egypt and settled in the promised land, each had its own tribal territory. After the death of Solomon the nation split into two kingdoms along tribal lines. The southern kingdom consisted of the territories of Judah and Benjamin, with the majority of the territory and power belonging to Judah. The remaining tribal territories made up the northern kingdom, with the offspring of Joseph's sons Ephraim and Manasseh holding the lion's share of the land. Therefore, the stick of Judah represented the tribes of the southern kingdom, and the stick of Joseph represented the tribes of the northern kingdom. God said that He had Ezekiel join the two sticks into one to visually demonstrate His promise that "I will make them one nation and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all."
(Ezekiel 37:22) *

CONCLUSION
The contradictions between the Book of Mormon and the Bible constitute a most serious obstacle to accepting the Book of Mormon as Latter-day scripture supplemental to the Bible. The Bible came first, not the Book of Mormon. And whereas the Bible is organically linked to the earthly ministry of Jesus Christ by extensive surviving manuscript evidence going back as far as A.D. 125-30, the Book of Mormon is wholly lacking in any such evidences of ancient origin. Is it not reasonable, therefore, to make the Bible the standard for judging the Book of Mormon, and not the other way around? If we accept the Bible as our "measuring stick" for spiritual truth, the Book of Mormon must be rejected.

Acts 17:10-11 (KJV)
"And the brethren immediately sent away Paul and Silas by night unto Berea: who coming thither went into the synagogue of the Jews. These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so."

1 Thessalonians 5:21 (KJV)
"Prove all things; hold fast that which is good."

1 John 4:1 (KJV)
"Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world."
