The LDS church teaches that people like me, i.e., former members of the church, are destined to be miserable, and that we are in the clutches of Satan. We are as Judas--traitors who would kill Christ if we could. This sounds harsh, and indeed it is. It sounds like one of those old 19th-century teachings (like blood atonement) that the church has swept under the rug. But, alas, this is one of the old teachings that is still alive and kicking in the modern church. In the current manual Teachings of the Presidents of the Church: Joseph Smith, published at the direction of the First Presidency (and the only extra-scriptural material permitted to be used by Priesthood and Relief Society teachers in the church) is found lesson number 27, titled "Beware the Bitter Fruits of Apostasy." From that lesson comes this quote, which is representative of the tenor and thrust of the entire lesson:
There is a superior intelligence bestowed upon such as obey the Gospel with full purpose of heart, which, if sinned against, the apostate is left naked and destitute of the Spirit of God, and he is, in truth, nigh unto cursing, and his end is to be burned. When once that light which was in them is taken from them they become as much darkened as they were previously enlightened, and then, no marvel, if all their power should be enlisted against the truth, and they, Judas-like, seek the destruction of those who were their greatest benefactors. . . .
. . .
When you joined this Church you enlisted to serve God. When you did that you left the neutral ground, and you never can get back on to it. Should you forsake the Master you enlisted to serve, it will be by the instigation of the evil one, and you will follow his dictation and be his servant.
I believe that one reason why active Mormons often choose not to associate at all with former members of the church is that they actually believe that former members are possessed by Satan, as the above quote from Joseph Smith unequivocally states.
