What would motivate someone who believes in literally 'nothing' (including no Satan) to call their movement a religion, specifically a religion with the name of something that doesn't exist according to their own teaching in it's name?
I'll grant that in the late 1960's heavy drug use influenced many people to do many things which defy logic. So I can understand the organization being founded. But as a movement which has a central office, and calls itself a church, it seems to have never come to grasp with the initial logical contradictions inherent in it's foundation.
Now, with that said, to address the main point of the article linked above. Death is, for many people, a terrifying event, or moment in life. This is something which every human faces, without exception. We all must prepare ourselves for what we will face at the end of life as we know it.
One of the greatest questions all humans ask themselves is a form of this:
"What will happen on the other side?"
Christianity has the obvious answers of 'Have faith in Christ, and you go to paradise; live for self, and you will spend eternity separated from your Creator.' Other faiths have various answers ranging from some form of paradise to re-incarnation to absolutely nothing. This organization takes a slightly different tact. They state that there is nothing after death, and that the afterlife one experiences is the aftermath of their actions while alive. They want their memories to live on after they do.
This strikes me as an outlook with very little hope. While we can have no scientific discussion on what happens to any sort of spirit or soul postmortem, there is a curiosity about it. People with near-death experiences often speak of seeing a light at the end of a tunnel, or other events in which they see family members, or familiar places. Are these visions manifestations of fearful minds, calming images given by a Loving Creator, absolutely nothing, or something completely different? I think the only people who know without any doubt are the ones who have preceded us in death.
Perhaps some day we will have the means to discover exactly what people experience in their last moments without the need to experience it ourselves. Until then we are left to speculation.
Or are we? For those of us who have placed our faith in Christ, we have His Word. With study, we can see a glimpse of what awaits us in eternity. Christ promises things from preparing a place in His Father's house, to feasts, to a new Heaven and a new Earth at some point in the future. That is hope. That is something to which we can look forward with eager anticipation. Faith and Hope are wonderful things.
