Over 20 years ago I married a beautiful woman from Peru who came from an active LDS family. But little did I know that there would be gospel doctrine mixed with spiritualism mixed into my in-laws belief system hat would come up that would be very difficult for me to manage on my own. This discussion is to help find some valid gospel centered resources and answers to these questions. My focus is on the conditions of the spirit world after death.
From Duane S. Crowther's book 'Life Everlasting"A definitive Study of Life After Death'. Page 236 Heading - Evil spirits sometimes wander on Earth indiscriminately; righteous spirits return only for a purpose.
"Spirits who reside in paradise are carefully organized and controlled through principles of righteousness. They are not free to wander about the earth without an assigned purpose. In contrast, the spirits in spirit prison are able to "wander aimlessly, not knowing where to go or what to do until they accept the gospel. Those spirits who are under Satan's influence are given ample opportunity to haunt the earth and create whatever mischief and evil they choose. Elder Parley P. Pratt wrote that. Many spirits of the departed, who are unhappy, linger in lonely wretchedness about the earth, and in the air, and especially about their ancient homesteads, and the places rendered dear to them by the memory of the former scenes."
Crowther goes on to quote more from Parely P. Pratt's book, Key to the Science of Theology. Which was published by the church up till somewhere about 1912 Which also contains for me a very surprising chapter on how the spirits of the dead can overtake and possess a mortal body, and that they are the cause of much demonic possession.
This was all news to me and I can't wrap my head around this. Listed below are my basic fundamental understanding of what I understand the Gospel to be with regards to conditions of the post mortal spirit world and un-embodied spirits in this world.
There is a veil that separates this life from the next life.
Only priesthood power has the ability to allow passage through a veil.
The spirit world is divided into Paradise and Prison. The prison is as much literal as figurative in that those in spirit prison would have to be limited in their sphere of movement and association because they were not preached the Gospel until after Christ had died on the cross.
The only un-embodied spirits roaming the earth on our side of the veil are Satan and his hosts.
That only messengers from God that visit from the pre-mortal and post-mortal realms can do so only because they are authorized by priesthood power.
What I want to know is, are my above statements correct or not. And if not what authoritative Gospel resources can help to clarify.
