I'm a member of the Church of Jesus Christ of Latter-day Saints, also known as the Mormon Church. You can see by the official name that we are a Christian church. But still there are those who say Mormons are not Christians. How can anyone look at another person's belief system and say, "No, that's not really what you believe." To me, a Christian is one who follows Jesus Christ.
Of course, there are different definitions of the word "follow."
You can "follow" a sports team by watching what they do and talking about it a lot, even if you don't play the sport yourself.
Or you can "follow" in someone's footsteps, either by literally stepping in the footprints they have left, or by trying to do what they did.
My religion is a combination of both types of following. We talk a lot about Christ. We study his life and teachings. All of our prayers and ordinances are done in His name. We also do the best we can to live as he did, and incoroporate his commandments and teachings into our everyday lives. If that doesn't qualify as Christian, what does?
