Do you believe Mormons are Christians?

[Joe Biden 2020]

No, they may claim to believe in Jesus Christ, but in their mind you have to be a Mormon in order to go to heaven, plus they added a third testament to the Bible "The Book of Mormon", which is in direct violation of Revelation 22:18, "For I testify unto every man that heareth the words of the prophecy of this book.  If any man shall add unto these things, God shall add unto him the direct plagues that are written in this book:"  They have their reward coming to them, and it won't be pretty.

We, as Christians, believe that Jesus Christ is the only way to heaven and that without Him nobody gets to heaven.  You don't have to be a member of any particular domination, just believe that Jesus Christ died on the cross for your sins and that He is risen from the dead.

My fundamentalist teachers tought me the same thing, but I thought the books of the Bible were written individually. Why would John refer to the entire Bible while he was writing Revelation? It specifically mentions prophecy, so couldn't that be referring to just Revelation in particular? Not trying to argue, just asking a question.

The Bible was penned by 39 individuals, but authored by God.  All Scripture is God-Breathed.  Thus, the individuals wrote what God showed them.  That includes both the Old and New Testaments.

Here's why they aren't:

If you were baptized in one Christian denomination and wish to convert to another, you don't need to be rebaptized. Churches will accept the other denom's baptism as a valid Christian baptism. However no Christian denomination accepts Mormon baptisms as valid. Any Mormon wishing to convert to the ELCA would have to be rebaptized. Any baptized Catholic, Methodist, Baptist, etc. would not. Furthermore anyone wishing to convert to Mormonism who was baptized in a Christian denomination would have to be rebaptized as well.

i see what you're saying, but "baptism" doesn't make one go to heaven or not go to heaven.  Baptism is a mere public profession that one has come to faith in Jesus Christ, which is why you're correct that other Christian denominations accept one another's baptism, whether by immersion or by sprinkling.  Unless Mormons have accepted Jesus Christ as their personal Lord and Savior, they cannot enter the kingdom of heaven.  That rule applies to every single person on the face of the earth, no matter what persuasion or ethnicity they are of.  Your good works cannot save you, they are only a by-product that you have been saved.  That's where Mormons get it kind of backward.  They are, for the most part, very good and very moral people and very respectable in society, but that doesn't save them.

So, in reality, the big question is not whether a certain group of people are Christians, its whether a person has accepted Jesus Christ as their personal Lord and Savior.
