If their beliefs were more in line with Christian beliefs, then they would more likely be welcome in the fellowship of believers. Why would the LDS want in?
When the light rested upon me I saw two personages, whose brightness and glory defy all description, standing above me in the air. One of them spoke unto me, calling me by name and said, pointing to the other - ‘This is My Beloved Son. Hear Him!’ My object in going to inquire of the Lord was to know which of all the sects was right, that I might know which to join. No sooner, therefore did I get possession of myself, so as to be able to speak, than I asked the personages who stood above in the light, which of all the sects was right (for at this time it had never entered into my heart that they were all wrong) - and which I should join. I was answered that I must join none of them, for they were all wrong; and the Personage who addressed me said that all their creeds were abomination in His sight; that those professors were all corrupt (Pearl of Great Price History, 1:17-19).
All Christianity is corrupt; why join in with corruption?
Good point.
Call us “whores of Babylon” that is Christians and until a few years ago bristle at the thought anyone would refer to you as such and now “I want to be called a Christian” and if you don’t “I’ll stamp my feet and hold my breath”.
Merchandising, merchandising, merchandising...
Christianity has great brand name recognition...
PR in order to worm their way in to gain converts among unsuspecting/uneducated Christians.
