The ONLY model for a correctly functioning family, is God's model of Heaven.
It is very simple.
God creates all children of God (Sons of God/Souls) simultaneously.
All of these children are perfectly equal and identical and loved equally. They all love each other equally.
NONE of the children are the CAUSE of each other. They are not Father OR Children to each other. There is NO CAUSALITY between them. They neither cause nor affect each other.
God is their only Father.
God's family has only these levels:
2. All of His children as equals
3. The children of each child
At all times, you and your brothers are ALWAYS the direct creation of God, and there is nothing else in-between you and God. You do not accrue a lineage of grandparents.
Each son of God also creates, and extends God's love, to produce additional beings who are the children OF children. These are the ONLY part of reality that are truly children of YOU - creations within your being. These children remain only in Heaven and do not incarnate into bodies.
The only correct functioning then is to recognize that ALL CHILDREN OF GOD share the same single Creator - the Holy Father/Mother - God.
This means that there is absolutely ZERO cause or effect between individual sons. Your brother does not cause you. You do not cause your brother. Therefore THERE IS NO horizontal causality between brothers. All you can do is share love with "others".
Anything else that seems to happen, any other dynamic of not being equal to others, any ARTIFICIAL relationship structure such as human parents vs human children, or bosses vs employees, or strangers doing something to you, or you being able to attack others, or some group having power over you, or laws which work against God's family structure, is DYSFUNCTIONAL.
It becomes inherently dysfunctional the instant that you believe your brother can or does do something to you. This is literally the belief that he is the cause of you, meaning you think he is your creator or father, and you are his child. You are positioning yourself as the effect of him. You are NOT the effect of any brother. You are only the effect of God.
Believing otherwise instantly leads to dysfunction where suddenly it seems possible that individual beings are able to attack each other. "Attack" in all its form is an attempt to implement HORIZONTAL CAUSALITY, which the Course refers to as "horizontal perception". Within this horizontal perception, it seems that one brother causes another, one object causes another to react, one cause on the SAME LEVEL causes effects on the SAME LEVEL.
Your brother is on the same level as you. There is no causality on the same level. This level you are on is the EFFECT of a higher level. To believe that your brother is the cause or effect of you is LEVEL CONFUSION.
How about this. How about you recognize that NEVER EVER has there EVER been a cause coming from ANY BROTHER EVER. All throughout history, all throughout your life, all of your experiences, even in childhood, NEVER has there been causality coming from other people toward you, and you have NEVER done anything to anyone else. And right now, you are 100% responsible for EVERYTHING YOU CHOOSE TO DO TO YOURSELF, an there is ABSOLUTELY NOTHING ELSE that can happen to you against your will because there is NO OTHER CAUSE on the level of your brothers or the level of the world.
What if it is ABSOLUTELY IMPOSSIBLE for any brother to cause or attack you EVER? And what if no-one has EVER done so? Where does that leave you? It leaves you in a position where you MUST acknowledge that ONLY YOU are the chooser who makes stuff happen to you. Anything you are experiencing YOU MUST HAVE PUT THERE. Anything you feel you want to feel. Any upset you have you choose. Any sickness is put there by yourself. And if you do not choose die nothing can cause you to die. This is the truth of the Course.
No-one else ever causes you anything. You are 100% responsible for everything. "You chose sickness and death and therefore can abolish both."
