The Church of Jesus Christ of Latter-day Saints has lost its Theology. Entirely. During Gordon B. Hinckley's Presidency, they didn't say very much about their theology, or the things they said were conservative enough to make it ambiguous.
But now, (and perhaps also at the very end of Hinckley's life, it is hard to tell when things were written) the Church has apostatized (fallen away) from many of its former views.
The most significant one which I see is that they have entered into idolatry by beginning to worship Jesus Christ. This is the next step (and final straw) on top of the Talmage theological reformation which took place beginning around 1915.
The "correct," original position:
Heavenly Father (Father Adam, if we want to get specific) is the only God whom we worship. Also, we pray directly to him.
We are all spirit sons and daughters of our Heavenly Father and Mother, and Jesus is their eldest son, firstborn in the spirit world.
Read Moses Chapter 1 in the Pearl of Great Price. It clarifies that Worship of the Only Begotten is a tactic of Satan, and that Jesus teaches that we should exclusively worship God.
