So LDS are called saints which is mention 389 times in the scriptures and the name Christain is only mention 3 times.
Paul always called those who took on the covenant of Jesus Christ and keep the commandments, Saints!
The LDS call themselves saints, we do not. We call you "Mormons" or have you noticed?
You may call yourself the Queen of Sheba or the President of the United States, it doesn't make it so.
