Ok I am a Mormon to start. Christianity is when a religion believes in Christ and, from a religious standpoint, holds Christ as one of the centerpieces of the religion. so for you to say The Church of JESUS CHRIST of Latter Day Saints doesn't believe in Christ clearly shows you don't have the first clue of what you are talking about so I'm sorry but your argument is completely invalid.
Ok let me clear some things up. First off, there are certain parameters that defines a faith as Christian. You do have to believe that Jesus Christ is your savior and is GOD!! You believe in the HOLY TRINITY and believe God, The Holy Spirit, and Jesus are the same person. I know for a fact that Mormonism believes that they are all DIFFERENT people. You also believe that God created all things and is the one and only true God. So it is preposterous to believe that God is just a really good person from another planet and was given Earth. We are creations of God so we CANNOT also become a God. What you do in life does not define where you go, Hell or Heaven. It is clearly stated in the Bible that Jesus saves us, and all we need to do is to believe and love with all our hearts. We do not have to DO anything physically. All God asks of us is to believe in him since he is the one true God. So YOU obviously have no idea what you are talking about.
Don't play with me. You know what I mean. I mean you do not have to physically do anything to earn God's love. You still do deeds for him out of faith. You do things out of your faith. However, if you do these things you will go to heaven. You do not have to earn your way into heaven. Doing "extra" things won't send you to heaven. Doing what is right in God's eyes and believing with all your heart and strength and mind is what really gets you into heaven. You don't have to do anything. You do things due out of your love and faith in him. Further more, why would you not believe that the Bible is totally trustworthy and decide to supplement and correct it with the book of mormon or the pearl of great price? Does it not state in the Matthew 5:48 that God is perfect? And if God is perfect how can something he gave to us to follow be flawed? Does it not also state in Revelations 22:18-19 that whoever adds anything to his book will be added to the plagues described in his book? Don't state things from the Bible if you don't trust in it wholly.
