Mormonism and doctrine/Prophets are not infallible
The fallibility of prophets
Questions and Answers
Question: Do Mormons consider their prophets to be infallible?
Latter-day Saints do not believe that prophets and apostles are incapable of error, despite being called of God and receiving revelation
Some people hold inerrantist beliefs about scriptures or prophets, and assume that the LDS have similar views. This leads some to assume that prophets are infallible. 
Joseph Smith himself taught that ‘a prophet was a prophet only when he was acting as such’. The Church has always taught that its leaders are human and subject to failings as are all mortals. Only Jesus was perfect, as explained in this statement from the First Presidency:
The position is not assumed that the men of the New Dispensation —its prophets, apostles, presidencies, and other leaders—are without faults or infallible, rather they are treated as men of like passions with their fellow men."
Lu Dalton, writing in the Church's periodical for women, explained:
We consider God, and him alone, infallible; therefore his revealed word to us cannot be doubted, though we may be in doubt some times about the knowledge which we obtain from human sources, and occasionally be obliged to admit that something which we had considered to be a fact, was really only a theory.
Other authors have long taught the same thing:
1887 B. H. Roberts, Letter written November 4, 1887, London, Millennial Star 49. 48 (November 28, 1887): 760-763; a portion of which reads: “Relative to these sermons [Journal of Discourses] I must tell you they represent the individual views of the speakers, and the Church is not responsible for their teachings. Our authorized Church works are the Bible, Book of Mormon, Doctrine and Covenants, and the Pearl of Great Price. In the Church very wide latitude is given to individual belief and opinion, each man being responsible for his views and not the Church; the Church is only responsible for that which she sanctions and approves through the formal actions of her councils. So it may be that errors will be found in the sermons of men, and that in their over zeal unwise expressions will escape them, for all of which the Church is not responsible” (762)
1889 Charles W. Penrose, Editorial: Judge Anderson and ‘Blood Atonement,’ Deseret Weekly 39. 25 (December 14, 1889): 772a-773c. [Editor is Charles W. Penrose; in his response to the lengthy statement by Judge Anderson, he quotes from the same pamphlet which the Judge had quoted from: Blood Atonement, by Elder Charles W. Penrose, published in 1884; Penrose quotes a statement which the Judge had not] “’The law of God is paramount. When men give their views upon any doctrine, the value of those views is as the value of the man. If he is a wise man, a man of understanding, of experience and authority, such views are of great weight with the community; but they are not paramount, nor equal to the revealed law of God’” (773ab)
1892 21 March 1892: Elder Charles W. Penrose, at the time a counselor in the Salt Lake Stake Presidency: "At the head of this Church stands a man who is a Prophet . . . we respect and venerate him; but we do not believe that his personal views or utterances are revelations from God." Millennial Star 54 (21 March 1892): 191
1902 Joseph F. Smith to Lillian Golsan, July 16, 1902. "[T]he theories, speculations, and opinions of men, however intelligent, ingenious, and plausible, are not necessarily doctrines of the Church or principles that God has commanded His servants to preach. No doctrine is a doctrine of this Church until it has been accepted as such by the Church, and not even a revelation from God should be taught to his people until it has first been approved by the presiding authority–the one through whom the Lord makes known His will for the guidance of the saints as a religious body. The spirit of revelation may rest upon any one, and teach him or her many things for personal comfort and instruction. But these are not doctrines of the Church, and, however true, they must not be inculcated until proper permission is given.” - Joseph F. Smith Correspondence, Personal Letterbooks, 93–94, Film Reel 9, Ms. F271; cited in Dennis B. Horne (ed.), Determining Doctrine: A Reference Guide for Evaluation Doctrinal Truth (Roy, Utah: Eborn Books, 2005), 221–222. Also in Statements of the LDS First Presidency, compiled by Gary James Bergera (Signature, 2007), page 121. Bergera indicates it is a letter from JFS to Lillian Golsan, July 16, 1902.
1907 March 26, 1907. [The following was first published in “An Address. The Church of Jesus Christ of Latter-day Saints to the World”, in Millennial Star 69. 16 (April 18, 1907): 241-247; 249-254; also in Improvement Era 10 (May 1907): 481-495; reprinted also in Messages of the First Presidency, Volume IV, compiled by James R. Clark (Bookcraft, SLC 1970): 142-157; “We refuse to be bound by the interpretations which others place upon our beliefs, or by what they allege must be the practical consequences of our doctrines. Men have no right to impute to us what they think may be the logical deduction from our beliefs, but which we ourselves do not accept. We are to be judged by our own interpretations and by our own actions, not by the logic of others, as to what is, or may be, the result of our faith”, page 154.
1921 B.H. Roberts: As to the printed discourses of even leading brethren…they do not constitute the court of ultimate appeal on doctrine. They may be very useful in the way of elucidation and are very generally good and sound in doctrine, but they are not the ultimate sources of the doctrines of the Church, and are not binding upon the Church. The rule in that respect is—What God has spoken, and what has been accepted by the Church as the word of God, by that, and that only, are we bound in doctrine. When in the revelations it is said concerning the Prophet, Seer, and Revelator that the Church shall “give heed unto all his words and commandments which he shall give unto you as he receiveth them—for his word ye shall receive as if from mine own mouth, in all patience and faith”—(Doc & Cov., Sec. 21)—it is understood, of course, that his has reference to the word of God received through revelation, and officially announced to the Church, and not to every chance word spoken.
The prophets are not perfect, but they are called of God. They may speak as men, but may speak scripture as well. Every person may know for themselves whether they speak the truth through the same power that their revelation is given: the power of the Holy Ghost.
Question: Can a prophet make mistakes?
The principle that the Lord will not ever allow the President of the Church to lead the Church astray means that He will not allow that man to lead the Church into apostasy
One part of knowing that the Church of Jesus Christ of Latter-day Saints is true is knowing whose Church it really is and that our Savior lives and leads the Church today. It is knowing that he has entrusted a living Latter-day Prophet with all the keys necessary to direct, act, and receive what is needed to guide and direct the Church under the Lord’s direction whose Church this is.
Many Latter-day Prophets have taught that the Lord will not suffer the President of the Church to ever lead the Church astray. This is a true principle, but it only makes sense in light of the destiny of the Church as taught and revealed in Latter-day Saint scripture. Unlike previous dispensations, the Lord’s Church on earth today will not fall into apostasy, speaking of the body of the Church as a whole and not individuals.
This statement does not mean that the Lord's servants are perfect or that they will never make mistakes, display weaknesses, sometimes be irritable, have bad breath, or display the characteristics of old age
The principle that the Lord, who is the head of the Church will not ever allow the President of the Church to lead the Church astray means that He will not allow that man to lead the Church into apostasy. It does not mean that his servants are perfect or that they will never make mistakes, display weaknesses, sometimes be irritable, have bad breath, or display the characteristics of old age.
In a discourse to the Saints on March 21, 1858, President Brigham Young asked:
Can a Prophet or an Apostle be mistaken? Do not ask me any such question, for I will acknowledge that all the time, but I do not acknowledge that I designedly lead this people astray one hair’s breadth from the truth, and I do not knowingly do a wrong, though I may commit many wrongs, and so may you. But I overlook your weaknesses, and I know by experience that the Saints lift their hearts to God that I may be led right" 
We should receive and follow the counsel “words and commandments” of the current President of the Church “in all patience and faith”
There is also another principle involved here that we should receive and follow the counsel “words and commandments” of the current President of the Church “in all patience and faith” with great promises attending (Doctrine and Covenants 21: 4-9).
Question: How is it possible for a Church leader or prophet to have been influenced by racism, yet be consistent with the Lord not allowing prophets to lead the Church astray?
The goal of the Church is to bring people unto Christ
This is a difficult question. At face value, the idea that the Lord will not allow prophets to lead us astray seems to be in direct conflict with the Church acknowledging that early Church leaders and prophets were influenced by certain racist tendencies of their times. For example, how could the Priesthood ban have been implemented and yet be consistent with the prophets "not leading the Church astray?".
The first thing we must do is step back and see what the Church and prophets are all about.
What is the goal of the church?
According to Spencer W. Kimball, and reaffirmed by the other prophets it is as follows:
First, to proclaim the gospel of the Lord Jesus Christ to every nation, kindred, tongue, and people; Secondly, to perfect the Saints by preparing them to receive the ordinances of the gospel and by instruction and discipline to gain exaltation; Thirdly, to redeem the dead by performing vicarious ordinances of the gospel for those who have lived on the earth. (See Ensign, May 1981, p. 5.) All three are part of one work—to assist our Father in Heaven and His Son, Jesus Christ, in their grand and glorious mission “to bring to pass the immortality and eternal life of man.” (Moses 1:39.) I renew that declaration today. 
The purpose of the Gospel is to bring people to Jesus Christ. The Church is the organization that Jesus set up on the Earth to bring people back to Jesus and back to God so we can be joint heirs with Christ. (Romans 8:17.)
The prophets will not lead the Church astray from the mission of leading people to Christ: This does not exempt prophets from saying or doing things that are incorrect
Will the prophets lead us astray from this mission. No. They won't. They will keep us on that path and we should follow them.
Will they say things, do things, and even make policy that isn't the best, or even is incorrect. Certainly. Just as one example, Joseph Fielding Smith did not believe that men would even go to the moon. He stated in the first edition of Answers to Gospel Questions,
Naturally the wonders in the heavens that man has created will be numbered among the signs which have been predicted—the airplanes, the guided missiles, and man-made planets that revolve around the earth. Keep it in mind, however, that such man-made planets belong to this earth, and it is doubtful that man will ever be permitted to make any instrument or ship to travel through space and visit the moon or any distant planet.
He later accepted a flag from the Apollo astronauts. When asked about this by a reporter, he stated, "Well, I was wrong, wasn't I?"
In Jonah chapter 3 it says,
4 And Jonah began to enter into the city a day’s journey, and he cried, and said, Yet forty days, and Nineveh shall be overthrown.
But Nineveh wasn't overthrown. The people repented and the Lord spared them. This really upset Jonah. (This doesn't even get into the fact that he first ran away.)
The Lord uses imperfect people to run his Church
The Lord uses imperfect people to run his Church. He has promised he will make it all right in the end.
Karl G. Maeser taught:
On one occasion he was going with a group of young missionaries across the alps. They were crossing a high mountain pass on foot. There were long sticks stuck into the snow of the glacier to mark the path so that travelers could find their way safely across the glacier and down the mountain on the other side.
When they reached the summit, Brother Maeser wanted to teach the young elders a lesson. He stopped at the pinnacle of the mountain and pointed to those sticks that they had followed. And he said, “Brethren, behold the priesthood of God. They are just common old sticks, but it’s the position that counts. Follow them and you will surely be safe. Stray from them and you will surely be lost.” And so it is in the Church. We are called to leadership positions and given the power of the priesthood. And we are just common old sticks, but the position we are given counts. It is separate and apart from us, but while we hold it, we hold it. 
If we go in with the expectation that the prophets will never do or say anything wrong, we will be disappointed
If we go in with the expectation that the prophets will never do or say anything wrong, we will be disappointed. There are more examples of this than the one you gave. Even Joseph Smith was reprimanded by God on more than one occasion.
Just a few examples from history (There are also reprimands in the D&C) They started doing Baptism for the dead in the river in Nauvoo - until God stopped them. They started doing sealings of adoption- until God stopped them. Why didn't God stop the race issue? He did...but He just did it later in his time frame for His purpose.
So again, If we go in with the expectation that the prophets will never do or say anything wrong, we will be disappointed. Prophets are learning and are being taught just as we are learning and being taught. Bruce R. McConkie stated that quite clearly. 
But, if we go in with the expectation that the prophets will keep us on the Gospel path, complete with the ordinances we need to return to our Heavenly Father, then we will know that the prophets will never lead us astray.
In John 6, Jesus taught hard things:
66 ¶From that time many of his disciples went back, and walked no more with him.
67 Then said Jesus unto the twelve, Will ye also go away?
68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
We will get things wrong, because we are NOT Jesus Christ: He allows us to learn as we go along
Jesus has taught the words of eternal life. This is his Church. We will get things wrong, because we are NOT Jesus Christ. He allows us to learn as we go along. The prophets will not lead us astray from that goal of eternal life.
I also fall back onto the truthfulness of the Book of Mormon. In my mind, the evidence is very clear. Joseph Smith could not have written the Book of Mormon in 1830. Nobody could have done that. There were things that Joseph Smith and scholars of the day did not know that are contained in the book. They would have written the opposite based on the science of the day.
If the Book of Mormon is true, then Joseph Smith is a prophet of God. It also means we have a prophet today. Will they lead us astray? Is that statement even true that they won't? The prophets will not lead us astray from the Gospel path. Can they be incorrect on other issues-even involving the Church? Yes, they can. But, that isn't why we have a prophet. We have a prophet to help us return to our Heavenly Father. As such, we follow him. God will make it all right in our eternal lives.
Neil L. Andersen (2012): "A few question their faith when they find a statement made by a Church leader decades ago that seems incongruent with our doctrine"
Neil L. Andersen:
A few question their faith when they find a statement made by a Church leader decades ago that seems incongruent with our doctrine. There is an important principle that governs the doctrine of the Church. The doctrine is taught by all 15 members of the First Presidency and Quorum of the Twelve. It is not hidden in an obscure paragraph of one talk. True principles are taught frequently and by many. Our doctrine is not difficult to find.
The leaders of the Church are honest but imperfect men. Remember the words of Moroni: “Condemn me not because of mine imperfection, neither my father … ; but rather give thanks unto God that he hath made manifest unto you our imperfections, that ye may learn to be more wise than we have been” (Ether 12:6)—(Click here to continue)
"Approaching Mormon Doctrine," LDS Newsroom (May 2007): "Not every statement made by a Church leader, past or present, necessarily constitutes doctrine"
Not every statement made by a Church leader, past or present, necessarily constitutes doctrine. A single statement made by a single leader on a single occasion often represents a personal, though well-considered, opinion, but is not meant to be officially binding for the whole Church. With divine inspiration, the First Presidency (the prophet and his two counselors) and the Quorum of the Twelve Apostles (the second-highest governing body of the Church) counsel together to establish doctrine that is consistently proclaimed in official Church publications. This doctrine resides in the four “standard works” of scripture (the Holy Bible, the Book of Mormon, the Doctrine and Covenants and the Pearl of Great Price), official declarations and proclamations, and the Articles of Faith. Isolated statements are often taken out of context, leaving their original meaning distorted. —(Click here to continue) 
Charles W. Penrose (1912): "Do you believe that the President of the Church, when speaking to the Church in his official capacity is infallible?"
Charles W. Penrose:
Question 14: Do you believe that the President of the Church, when speaking to the Church in his official capacity is infallible?
Answer: We do not believe in the infallibility of man. When God reveals anything it is truth, and truth is infallible. No President of the Church has claimed infallibility.
Question: How are Church members protected against error by leaders?
The Church's system of councils provides protection against the fallibility of a single man or leader
President Joseph Fielding Smith explained:
An individual may fall by the wayside, or have views, or give counsel which falls short of what the Lord intends. But the voice of the First Presidency and the united voice of those others who hold with them the keys of the kingdom shall always guide the Saints and the world in those paths where the Lord wants them to be.
Dallin H. Oaks explained how the Lord allows all His children to grow through struggling with problems:
Revelations from God . . . are not constant. We believe in continuing revelation, not continuous revelation. We are often left to work out problems without the dictation or specific direction of the Spirit. That is part of the experience we must have in mortality. Fortunately, we are never out of our Savior's sight, and if our judgment leads us to actions beyond the limits of what is permissible and if we are listening, . . . the Lord will restrain us by the promptings of his Spirit.
The Lord will not help his children avoid all stumbling and error; He will protect them from permanent harm to His work, as Boyd K. Packer taught:
Even with the best of intentions, [Church government] does not always work the way it should. Human nature may express itself on occasion, but not to the permanent injury of the work.
Question: Should Church members simply have "blind trust" in their leaders?
Lorenzo Snow: "because each member of the Church has a right to have that measure of the Spirit of God that they can judge as to those who are acting in their interests or otherwise"
Hardly, says President Lorenzo Snow:
There may be some things that the First Presidency do; that the Apostles do, that cannot for the moment be explained; yet the spirit, the motives that inspire the action can be understood, because each member of the Church has a right to have that measure of the Spirit of God that they can judge as to those who are acting in their interests or otherwise.
Question: Were Biblical prophets infallible?
The Bible itself does not support this claim
Some critics will protest that this standard is not applied to Biblical prophets, yet the Bible itself does not support this claim. One Bible commentator noted that the Biblical authors were not perfect, and that they made errors of expression even in the Biblical record:
Though purified and ennobled by the influence of His Holy Spirit; men each with his own peculiarities of manner and disposition—each with his own education or want of education—each with his own way of looking at things—each influenced differently from another by the different experiences and disciplines of his life. Their inspiration did not involve a suspension of their natural faculties; it did not even make them free from earthly passion; it did not make them into machines—it left them men. Therefore we find their knowledge sometimes no higher than that of their contemporaries.
Paul’s accounts even contain a contradictory account of his vision
Paul’s accounts even contain a contradictory account of his vision (Compare Acts 9:7 & Acts 22:9). Paul and Barnabas disagreed severely enough for it to disrupt their missions Acts 15:36–39. Peter and Paul also criticized the other’s writing 2 Peter 3:16 and behavior regarding the Church Galatians 2:11–16.
Question: How do Biblical prophets compare to modern prophets?
Biblical prophets and modern prophets are divinely called, but clearly are not perfect
To get a better idea of how prophets are limited yet still divinely called, it can be helpful to look at some examples of Bible prophets and compare them with modern prophets.
|Bible prophets||Modern prophets|
|Moses disobeyed God's instruction to speak to the rock and instead hit it. He then attributed the miracle to himself and Aaron, saying, "Must we fetch you water out of this rock?" He was chastized by the Lord afterward. (Numbers 20:)|
|Joshua was deceived by the inhabitants of Gibeon when they claimed to come from a far country so they could get a peace accord with Joshua. Then the Israelites found that instead of living a long distant away, that people from Gibeon lived among them. (Joshua 9:)||Gordon B. Hinckley was deceived by Mark Hofmann, who had done so in order to obtain money. Hofmann was even responsible for the death of some people. After some investigation, he was discovered and sentenced.|
|Gideon repeatedly asked the Lord for signs even though the Lord has said, "An evil and adulterous generation seeketh after a sign." (Judges 7:; Matthew 12:39)|
|Nathan told David that the Lord approved of his desire to build a temple, and that he should commence the project. The Lord later told Nathan that such was not His desire, and that he was to tell David that the temple would be built by another. (2 Samuel 7:)|
|Jonah felt some personal prejudices against Assyrians, to the point of expecting the Lord to give them fewer blessings than to Jews. (Jonah 4:1)||Brigham Young felt some personal prejudices against blacks, to the point of expecting the Lord to give them fewer blessings than caucasians.|
|Jesus' apostles were not always perfectly humble or modest. They once disputed over which of them would be the greatest in heaven. (Mark 9:34)||Joseph Smith was not always perfectly humble or modest. He once said he had "more to boast of than ever any man had." See here, though, to learn how critics misinterpret this event.|
A person could spend all day looking for examples of the Lord's chosen servants making mistakes, but such an activity does nothing to edify or strengthen people. In all of these situations, a prophet's weakness or mistakes do not make him any less a prophet, called of God to do His work.

Volume 6 link This statement, when understood in its proper context, doesn't appear to be a statement of personal pride at all. Joseph Smith read to the congregation 2 Corinthians 11 and then mimicked Paul in his "boasting." In its proper context, Joseph Smith was not acting in a proud manner at all but was using the rhetoric of Paul to defend his own authority as a prophet against those who were then proclaiming him a "fallen prophet." This statement, however, is used often in anti-Mormon literature as a criticism of the prophet and is used here only to show that even if he were in fact proud, it doesn't damage his authority as a prophet/apostles any more than it damaged Jesus' apostles' authority.
