In ancient Jewish thinking, when a man marries a woman, they become "one flesh".
The woman, by name, is an external attribute that the man adds to himself.
Sons, by name, are various attributes manifested from himself.
Daughters, by name, are various attributes of the man, manifested from himself, which are to be given away to worthy men, for them to become one flesh with.
Others who are made a part of the household, servants, concubines, etc, by name, are added, but are not made one with, nor do they come from. They live in the "house", and work in the "field", both of which represent the man in question as a whole, in certain different ways.
All family members are a part of the father in question, and all are still individuals with critically important names, and roles.
I stress, critically important names. Knowing what the names mean and inserting them while reading scripture is of the utmost importance. If you don't know that Jacob "struggles with flesh" and Israel "struggles with God", you miss the meat of the story.
So when Jacob fathered those 12 sons, he manifested by name, those 12 attributes of himself.
When we read about Isaac and Ishmael, we are still reading about "Abraham."
When we read about Esau and Jacob, we are still reading about "Isaac."
When we read about Reuben ... Benjamin, we are still reading about "Jacob."
YHWH only manifested one attribute from Himself, "Salvation."
This is why it's important that Y'Shua is the "only begotten Son."
When we see Abraham and Isaac, we see Isaac as an attribute of Abraham, but each remain their own individual.
It's hard to put this into words better than the bible already displays. The key is being able to look for it in the first place, which we have not been taught to do.
As stated carefully above, and in scripture, Y'Shua is not "God", YHWH is His God.
Even though He said "Before Abraham was, I AM", He never said He is God.
When your wife gives birth to your son, he becomes flesh and dwells among you. But he is not you.
He represents you.
He was always in the Father, as "seed", just not yet fully manifested until a certain day.
God as a physical man on earth is what the pagan religions before (and to this day) say. In and long before Y'Shua's day, it was considered blasphemy to do so (re: pharoah et. al.), and that's why the pharisees were eager to accuse Him of that claim, with partial understanding of the concept, but improper understanding of who He is and how He claimed to be.
"Then he brought me to the door of the gate of YHWH's house which was toward the north; and, behold, there sat women weeping for Tammuz." <-in essence, modern christianity on Christ and the trinity.
It's a valid concept. We just haven't been taught how to understand it, and therefore we errantly worship:
Christ as "God"
instead of
"Christ" as God.
And we errantly acknowledge Jesus, instead of YHWH through Jesus.
I don't think it can be explained by simply saying that they are 3 creatures, or 1 creature.
If you become like Christ, do you become God? Nope.
If you become like Christ, are you in the Father and the Father in you? Yep.
It should be a dish on the back burner, and served as desert, only when it's finished cooking.
The main course we should be baking is "Repent, for the kingdom of Elohim is at hand."
Again: "Then he brought me to the door of the gate of YHWH's house which was toward the north; and, behold, there sat women weeping for Tammuz."
Nimrod "miraculously fathered himself" as Tammuz, through his wife, then all three were called "god"
If we insist on pursuing this puzzle, we must be careful what we insist to others is the conclusion.
Mary's miraculous pregnancy has been turned into the above story. When it is intended to represent something more in line with Jewish family thinking.
Hope this helps someone who is struggling with the "trinity" concept.
