We're only different from the entire Christian world if you leave us out of it. One of our leaders gave a remarkable address on this subject recently, you can find it here: 
 
"The Only True God and Jesus Christ Whom He Hath Sent" 
 
Aside from that, all I can do is ask, if our entire religion is founded on the teachings of Jesus Christ, our belief on Him as the Savior of mankind, His divine birth, His infinite atonement, His sacrifice on Calvary, and His miraculous resurrection from the dead after three days time. If all this is the beginning and the end of our religion. (and it is) then what else should we call ourselves? lds.orgnull
