There is a view of what ACIM says, based around the idea that this universe is all there is.
It's a view that God created this universe, and thus created all the galaxies and planets, all bodies and objects etc.
People with this view will adopt a model of ACIM in which perception is projected onto God's creation.
They will then believe that false perception means a misinterpretation OF God's perfect creation, and a true perception means a perfectly accurate view of God's creation.
They also will then believe that knowledge is merely a slightly different or more direct way of seeing the SAME stuff that you saw with true perception. That this same world is kept and known.
And therefore to these people, forgiveness means that you forgive the world instead of attacking it, BECAUSE it is real. Because it is God's Kingdom, it's thought to to be your job to "forgive the Kingdom" and stop attacking it. As if "forgiveness means to "be loving toward what's really there."
Another side effect of this view is the belief that, in the separation from God, we DID NOT make a second world. There was no making of space or time by us. There was no forming of galaxies or planet Earth by us. There was no making of human physical bodies by us.
Essentially that there was no result from opposing God, no other world made, no effect producing a dream world, other than that you entered into some kind of egoic state of mind where you don't see heaven correctly. And then the correction of this lets you see heaven directly.
This leads to yet another strange occurrence, whereby since there is no "second world" covering over heaven, and you didn't make THIS world, any references in the course which refer to "the world" are now grouped together with references to egoic perceptions.
So when Jesus says something about "the world", which would be referring to the second world we made without God, and since it's believe such a world was never made be us, those same quotes are now thrown into a "must be an ego interpretation" bucket.
If any such statements suggest that "the world" is not real, is not created, is cruel, is in denial, attacks itself, is contradictory, or anything else that seems un-God-like, then such believers now have to put ALL of those statements into a "false perception" bucket. They have to be interpreted as being egoic mis-perceptions of what would otherwise be recognized as a perfect creation.
As such, since in this model there is no second world to assign anything to, and there is only the first world of the Kingdom of God, anything speaking about "this world" in a less than holy way is thought to be part of the ego's use of it, and NOT a statement about the world itself. Thus false perceptions/interpretations and projected meanings are now MIXED IN with factual statements about the INHERENT nature of the world.
This of course then strips away every single statement which might suggest "this world" is not God's Kingdom, and shuffles all of those facts into an ego bucket where they are safely tucked away and brushed under the carpet. If there is no second world, there is no world to ATTACH them to or associate them with or see them referring to, except "the ego's world".
The end result of all this is that, if you believe there never was a second world made in the separation, and if you believe that Earth is therefore literally God, as God's creation/extension, then you will be completely unwilling to question this world's authenticity.
Forgiveness then becomes a love-affair with the planet, in which we think that we should love what God created, and keep what God created. And forgiveness is no longer seen as UNDOING something that's unreal, but rather as "correctly seeing" something that IS real.
The fact that forgiveness would make what is forgiven DISAPPEAR, because you can ONLY forgiven illusions, becomes swept under the carpet. The notion that the world will disappear when recognized for what it is, as NOT God's creation, now becomes completely denied. There is no place for such a notion in a mindset that cannot accept that we made this world.
So now instead of forgiving the world in order you undo it, we would see our function as forgiving it as though it's something completely perfect and real that we've been mean to and need to apologize to and come to love again. Our entire relationship to this world and what it is thus vastly different when you think of it as God's creation and will, rather than the antithesis of God's nature.
In this model, which seem simple, there is simply God's creation and our perception of it. If we perceive it as anything other than God's perfection, we're seen to be doing something wrong. And if we perceive it as holy and perfect then we're doing something right. And direct cognition or knowledge is then thought to be almost identical to true perception - that true perception shows you what you will still continue to see in a state of knowledge.
But while this model seems simpler and, in and of itself has internal consistency, it still flies in the face of a great amount of what A Course in Miracles says. ACIM actually does say many many times in many many ways that we produced a second world. It says that we made a world opposite to God's world.
It also distinguishes clearly that this second world was DISTINCT from the ego's USE of this world. That ego projected meaning onto this world AFTER it was made by us. And that the Holy Spirit's REPURPOSING of what we made, is NOT a repurposing of the ego or of false perception, but a repurposing of a second world. We can see Earth reflecting heaven or hell, due to its neutral nothingness.
If God truly had created this world, the course would actually be somewhat easier to grasp. We would simply need to realize that we should love everything we see with the body's eyes. That it is all real. Another problem arises though, that the course does not speak well of the body. It even states that it does not really exist and is not God's creation.
In a mindset that thinks that this world IS God's creation, references to "the body" HAVE to take on a different meaning. If the course says the body "is nothing, which it is", this doesn't fit with the idea that God created the physical world. So then we have to shift the body once removed from the world, ie think of the term "body" not as referring to the physical "God created" body but rather to some kind of internal EGO PERCEPTION. And now, this should mean, that all references to "the body" are NOT talking about the physical body, bur about some internal interpretative state.
This kind of shifting of levels, this displacement of meaning and the need to completely redefine basic recognizable words, is an unfortunate side effect of this warped view of the course. Changing the meaning of words becomes necessary otherwise they would indeed imply that physical things are not God's Kingdom.
Indeed, "The body is clearly destructible and therefore not of the Kingdom" tells us that all physical things are not the Kingdom of God. And yet a belief system bent on believing the opposite to this will refuse to accept this meaning. Instead, "body" will be redefined as "must be something the ego is doing", because we don't like the idea that the actual human body is being identified as inauthentic and not of God.
In fact, what we find is that in many many areas, believing that God created this world leads to a completely OPPOSITE belief to what ACIM is actually saying. It produces beliefs which are absolutely and completely diametrically OPPOSED to the teachings of A Course in Miracles. 180-degrees opposite, heading AWAY from the truth instead of towards it.
So when the course tells us that Earth and the body are not of God, such a believer will believe they ARE of God. And when the course tells us that WE made this world, such a person will believe we DID NOT. And when we're told that false perceptions look at an illusion and make it seem real, such a person will invert this to mean that a false perception happens when you're looking at something REAL in an illusory way. And now as someone develops a special-love relationship with the planet, they THINK that they're entering into a genuine and holy relationship with it.
This whole view of ACIM leads to a complete flipping upside-down of almost everything it teachers. It puts reality and creation where it does not belong. It fails to see that the Kingdom of God is not like this world. It cannot comprehend that the physical body is not of God and nothing like our true nature. It completely reverses the meaning of false and true perceptions. It suggests that keeping the world is atonement, instead of its undoing. And it finds no reason to leave this world behind.
In this estimation of the world, it also includes having to believe that things which die are a part of God. That the seasons are God's will. That murder and rape and torture are entirely within what God allows to happen. That war and conflict and destruction are completely normal and natural. And that if you're not accepting them with love then you must be perceiving them with the ego.
As such, believers of "Earth is God" will insist that all of the dark twisted things of the world, when seen with true perception, will be seen as so holy and perfect that they will be deemed on par with God's will and nature. That it is absolutely natural for leaves to fall from trees, for animals to be squashed on roads, for weapons to be manufactured and guns shot towards bodies, for explosions to destroy buildings and for wars to destroy cities. These "destructions", these physical events and objects, are considered to be absolutely divine creations. And it should be fairly obvious that such a suggestion implies that God is far from sane.
It is one thing to forgive a world in which these things occurs, on the basis that they are NOT God's creations, which leads to seeing them in a better light with more forgiveness. But only as a stepping stone toward their dissolution. It's quite another to suggest we would not only love these things but even desire to KEEP THEM FOREVER, as an inherent part of what God is like. The PURPOSE of forgiveness is no longer seen as the end of even the potential for destruction, and instead is seen as a way to recognize that from God's view, destruction IS creation.
"You have expressed surprise at hearing how VERY different is reality from what YOU see. You do not realize the magnitude of that ONE error. It was so vast and so COMPLETELY incredible, that from it, a world of total unreality HAD to emerge. What else COULD come of it? Its fragmented ASPECTS are fearful enough, as you begin to LOOK at them. But nothing you have ever seen BEGINS to show you the enormity of the ORIGINAL error, which seemed to cast you out of Heaven, to shatter knowledge into meaningless bits of disunited perceptions, and TO FORCE YOU TO FURTHER SUBSTITUTIONS."
So God being all love created the world into which ones comes screaming to be trained to do things they don’t want to do. Later they are supposed to create other bodies to replace them so they can visit many doctors before dying.
No God had nothing to do with that. A very sick mind did.
