The only reasons I've ever found have nothing to do with our faith in Jesus Christ as the Savior. They're all about other, peripheral doctrines and teachings.

Check out the people here with "duck" in their screen-names…

When I was a kid, I heard someone say that Mormons weren't Christian. Having grown up in this church, that really confused me, so I asked my dad.

He said that if you define a duck as a waterfowl with white plumage,
webbed feet, a wide bill and a distinctive walk and call, you'd be
right… kind of. But you'd also be dead wrong in regards to wild
ducks, none of which are white.

If you define a Christian as a person who believes in and follows the
teachings of Jesus Christ, and believes (insert pet doctrine: trinity,
saved by grace alone, etc), then you'd be right… kind of. But you'd
also be dead wrong in regards to those who believe in and follow Him,
but don't believe in whatever pet doctrine.

I answered a question months (a year or two or three?) ago about why
some think that Mormons aren't Christian, using this analogy. It's
definitely caught on within the LDS community on Y!A, and I've even
seen some non-traditional non-LDS Christians using the term.

Invite her to a formal debate regarding whether Mormons are Christian or not. You will both have to formalize your definitions of "Christian" and give evidence. She'll need to bring proof that Mormonism doesn't fit, and you'll need to bring proof to the contrary.

Bring your Bible, BoM, and a hymn book if you have one.
Scriptures-
John 10:16- other sheep?
3 Nephi 15- defines the "other sheep"
2 Nephi 25:26- just read it- good stuff!
Helaman 5:12- why would we build on Christ if we didn't believe in him?
Article of Faith 1- short and sweet and to the point.
Hymns-
I believe in Christ
I stand all amazed
Jesus once of humble birth
(the list goes on)

Another option- Offer her a copy of the Book of Mormon and two colored pencils. Challenge her to read the book with both colored pencils in hand- Use one color to mark every reference to Jesus Christ- Lamb of God, Holy One of Israel, etc. Use the other to mark every direct quote, each time He speaks. (I've done this, and there are only two pages that didn't have any marks at all.)

Ultimately, you just have to remember that her opinion doesn't matter, and neither does the opinion of any other human being on earth- Father's is the only one that does, and He knows what you believe.

If she can't be decent to her students, then she needs to find another occupation.

Her definition of what a Christian is is definitely different than our definition. You see, we believe that we are Christian because we believe in Jesus Christ and know that he is our Savior. We have a greater understanding of his mission here on earth because we know about what happened before we came to earth and what will happen after we die. We understand fully what Jesus Christ’s mission was and who he is now. They do not.

They on the other hand believe in the Trinity. Which is a concept where they believe that God, Jesus Christ and the Holy Ghost are all one being without a body. I am sure you have come across this doctrine at your school.

It is no good arguing with your teachers because they will never change their minds. Especially when you are at a Catholic school and it is Catholic doctrine that they are teaching you. To survive in that situation you could try the following ideas:

1. Politely tell them that you will have to agree to disagree because you do not believe in the same things they do. If they do not respect this, and continue to try to badger you or persuade you that you are wrong, you will need to have a grownup involved in the situation to solve the problem. If your parents are Mormon also, then they should come to your defense and meet with the teachers. They should be very clear that they do not appreciate the treatment of you and your beliefs that they have been dishing out to you. They can be your best defense in stopping the badgering in your classes. They may also insist that she repairs the damage that she has already caused.

2. Do not engage in any further discussions with your teachers on this subject. Have you ever heard it said that you can never teach anyone about spiritual things when you argue? It is true. Only if the person listening has an open mind, and you both feel the presence of the Holy Ghost guiding what is being said can you have true communication and understanding. You know because you have felt it, I am sure, that the Holy Ghost is not present there. Especially when their are arguements and disagreements, so when they begin to put you down for your beliefs just walk away or tune them out.

I would not let them to continue to get away with their treatment of you though. Report it immediately to your parents. It takes two people to argue, so you be the mature one, and don’t argue.

3. Try talking with some of your friends outside of class. Ask them what they thought of what the teacher said about what you believe. Maybe this will give you a chance to straighten the misconceptions out and let them ask you some questions about what you believe in.

4. Remember that those who do think you are a nut are not worth having as friends. Would you judge someone so superficially? Of course not. If they are true friends they will want to hear your side of things and they will not be so quick to judge.

5. Remember that God may use you as an instrument in his hands. You have a unique opportunity to share the true gospel of Jesus Christ with others. The way you act, dress, and the things you say will reflect the way you believe. You have the opportunity to do alot of good. When they see that you are unwaivering in your testimony and that you are a great person, your classmates will remember that you were a Mormon. You see you are planting lots of little seeds that someday may decide to bloom.

6. Strengthen yourself. Not many 15 year olds have to be as strong as you are. You must stay close to your Father in Heaven. Do not go even one day without personal prayer to him, and in reading the scriptures. Preferably the Book of Mormon. I am sure that you study the Bible and the Catholics interpretation of it at school, but to be well grounded in your own faith you must read the Book of Mormon and pray. Ask God for help in your situation, and for a witness and testimony of the truthfulness of the gospel of Jesus Christ and his church. It is imperative that you are unshakeable. You, in a way are on a mission. For you are like a lighthouse on a hill. What you do and say matter and others will judge the church through you.

Strengthen yourself also by becoming involved in the activities that are available for LDS youth. Such as Mutual, stake dances, EFY, Youth Conference, camps, and seminary. These will give you a group of friends that have the gospel in common with you, and will help you to not feel so all alone.

If you would like to talk to someone who is LDS and a mother, you can email me by clicking my picture. I would be so glad to help you if I could. My best advice to you is to turn to your parents who love you. Don’t shut them out. At 15 it is so easy to do, but if you will give them a chance you will find that they will be there for you every step of

There are HUGE differences…
Note:
Regarding God the Father, the Bible emphatically states:

“The Lord is our God, the Lord is one!” (Deut. 6:4, Mark 12:29).
” I am the first, I am also the last and there is no God besides Me” (Is. 44:6, 48:12, 45:14,21-22).
“the Lord, He is God; there is no other besides Him” (Deut. 4:35).

The Mormon church teaches that “God was once a man who achieved godhood”. In Mormon theology, those who achieve godhood will have spirit children who will worship and pray to them just as we worship and pray to God the Father (Gospel Principles, p.290)

That is most defiantly not a Christian belief…

Becoming GODS…

“Brethren, 225,000 of you are here tonight. I suppose that 225,000 of you may become gods” (from a speech published in The Ensign, November 1975, 1980).
“In each of us is the potentiality to become a God” (Tribune, Oct. 7, 1974).
The Bible teaches that God is unchangeable and that He has eternally existed as God.

In Mormon theology, “God has flesh and bones” (that’s not a christian belief)
The Mormon church teaches that we have a Heavenly Mother as well as a Heavenly Father.
NOTE..
The Bible simply makes no reference whatsoever to a Heavenly Mother nor to a wife for God.
AND
Mormon leaders, Brigham Young in particular, have taught that Adam was God.

Joseph Smith didn’t lead with love. Smith led the people with an iron fist and the intimidation…IMO

You may not convince her to accept you as a “Christian,” but you can help her to respect your faith and beliefs. Don’t needlessly fight her on the issue. Show your faith in Jesus Christ by your actions. Years from now she could be having a conversation with a friend, “You know, people really give those Mormons a bad rap, but I had this wonderful student…”

Work hard, live the standards people expect you to live, and when your friends ask you about the Church be prepared to answer them from the scriptures and with clarity. It may take time, but you cannot force spiritual things. You can create a climate for walls to be broken down and seeds to grow. However, you must await that growth, not force.

Back off it, but strive to talk about Christ and set a good example for her. You’re not going to change her mind any time soon by arguing.
References :

Anyway, first of all, you need to talk to her alone – just tell her that whatever she believes is her right to believe but you didn’t like the way she singled you out in class, and made a target out of you for the other kids. You are sorry you lost your cool, but you really would like it if she would just keep her opinions general and not target you specifically.
By the way, is she teaching a religion class or a history/english class? If she is not teaching religion, your parents need to have a talk with the school administrators too – she is overstepping her bounds.

Anyway, my final bit of advice is this: Don’t try to convince her of anything. She will not change, she has been this way for years and will continue to be this way. Your beliefs are your beliefs, not someone elses, and you don’t need to worry what others think of them. Having faith means that sometimes you go through trials for believing what you do. That’s part of being a member of any religion.
Just hold your head high, and don’t give into the temptation to argue about it. If someone asks you about your beliefs, just tell them what you believe, but don’t let people bait you into arguments or fights.

Everyone believes different things. That’s what makes us all unique. Accept it and move on. Don’t let some overzealous teacher make you upset. Have the calm and composure to not care what she says.

You are never going to be able to change your teacher’s mind. And if she is bigoted enough to do this in front of your classmates, you risk having other problems with her (like grading you down based on personal feelings instead of grading your work based on the quality of the work).

Even though it is a Catholic school and they have the right to teach Catholic doctrines, I seriously doubt the headmaster is going to be okay with the teacher attacking students of another faith. Why? Because that risks the students parents pulling them out of the school, which means a loss of money. Plus, if the parents make a stink out of it and get the media involved, it could hurt the school’s standing in the community.

She doesn’t have to, nor will probably ever, agree with you. But that doesn’t give her the right to attack your faith, either.

1. Professing belief in Jesus as Christ or following the religion based on the life and teachings of Jesus.
A. Do the LDS meet this? Yes. We use the KJV Bible and Jesus is the center and salvation in our religion.

2. Relating to or derived from Jesus or Jesus's teachings.
A. Again Yes. Again KJV. Plus another testament of Jesus and His teachings thru the BoM. Whether your instructor believes or supports the BoM is not the point – that it is all about Christ and His teachings is.

3. Manifesting the qualities or spirit of Jesus; Christlike.
A. This one is up to you and other LDS members your Instructor may have know. We are all human and prone to mistakes, but on the whole we should be true to our faith. It matters – to us and to others who are watching.

4. Relating to or characteristic of Christianity or its adherents.
A. The characteristic we adhere to is Christ Himself – the atonement, the virgin birth, the savior, the crucifixion, the plan of salvation, the resurrection….

5. Showing a loving concern for others; humane.
A. Again, this lies on the members around.

6. One who professes belief in Jesus as Christ or follows the religion based on the life and teachings of Jesus.
A. The LDS do venerate Jesus as the Christ. We do believe He fulfilled the Messianic Prophecies. We do believe that salvation is provided only through His sacrifice and our coming to Him.

7. One who lives according to the teachings of Jesus.
A. Another one that's down to you.

As you can see – some of these are based in actual doctrine of a church, and some are based on your own personal behavior. Address each one individually. The most important thing is not to take it personally – this is not an attack on you or your beliefs, although it may feel like it. This is an attack coming from a place of fear -fear that maybe they are wrong? Or fear of something not familiar – something different. Maybe this is all about their own doubts. We seldom, as humans, care enough about another religion to bash it unless we percieve it as a threat.

My dad had a great saying – which I keep to myself in religious discussions, but is always in the back of my mind –
'Why assume malice over stupidity.' Maybe your teacher just doesn't know, and this is their antagonizing way of finding out. Remember, it is every bit as important to maintain Christ-like attitude as an example as it is to present doctrine. When all else fails, remember that we each one have our own free agency – They are free to insult and crucify – and you are free to do the same, or not. Hopefully, not.

Good luck.
