Paul teaches the elementary aspects when writing to the Romans:
"4 For just as we have many parts in one body and all the body’s parts do not have the same function, 5 so we, who are many, are one body in Christ, and individually parts of one another." Romans 12:4-5.
We (7th-day people) are gods in God's Infinite Realm and we incarnate "in" one another. You have an incarnation "in" me and I have an incarnation "in" you like all of our brethren as one body "in" God. We then incarnate inside ourselves to place our brethren around a great table just as we desire. Our brethren interact with members of our body and we interact with members of their bodies, which is how we come to know each of our brethren intimately from the inside out.
Those among us who are good and helpful are placed in high positions at our brethren's right hand. Those among us not so good are placed on the left side. Our outward appearance is governed by the way we judge well among our brethren, or judge badly placing the wrong brethren in high places leading eventually to our downfall. God judges between us and places us in the Mountain of God just as He desires in the same way we are placed in the Body of Christ. 1Cor. 12:18.
We are members of Christ's body in Heaven (Gen. 1:1) in the likeness of being members of God's body in God's Infinite Realm. We are also members of Adam's body in the Earth (Gen. 1:1) in the same way. These things are described in great detail in my book The Mystery Explained for those appointed by God to see.
