The greatest of love and peace to you, dear PSacto!
If I understand you correctly, the Gospel of John is "incorrect" in your opinion?
Not sure how you got that, but my answer would be, no, John's account is not "incorrect." Indeed, it is very accurate. It is the interpretation of what John meant... was speaking of/to... however, that is incorrect. Let's take a look:
The word "only-begotten" comes from the Greek "monogenes." That word means:
1) single of its kind, only a) used of only sons or daughters (viewed in relation to their parents) b) used of Christ, denotes the only begotten son of God
This descriptions is accurate, in that:
1) My Lord IS the only one of his kind: he was a spirit being whose body (vessel) was created INSIDE the spirit world. His "life" was conceived in the SPIRIT realm, IN spirit... and by spirit... so that he was "born" of a spirit "woman". Adham was a spirit being whose body (vessel) was created OUTSIDE the spirit world. HIS "life" was conceived in the PHYSICAL realm, when God took if from the earth (Hagar)... and that doesn't necessarily mean the planet earth. After his body was "born" from the earth (physical realm)... "life" was blown into it.
a) He IS the Son of God.
b) He is the Christ and only-begotten son of God... by Sarah (Jerusalem Above). She will have other children ("Be GLAD, you barren woman..."); however, the "head" of her "child"... has been been born. The creation is awaiting the "birth" of his BODY.
The word does NOT mean, as you and other erroneously suggest... made/begat by one alone. That error originates with the error in choosing the definition of the prefix "mono", which term means:
1) alone (without a companion), forsaken, destitute of help, alone, only, merely
Because of their erroneous belief in the Trinity, some have chosen to use the first definition ("alone (without a companion)"). But that's the wrong one. The term "monogenes" ALSO means... only child. Thus, Isaac was said to be Abraham's ONLY-BEGOTTEN son. Yet, Abraham did not have Isaac by himself - he had Sarah. AND... Isaac was NOT Abraham's only child or son. He was Abraham's only son... by SARAH.
And it is the same with my Lord. He is the Most Holy One of Israel's only-begotten son... by Jerusalem Above... the mother of ALL those who are born IN THE SPIRIT. Christ was the first of those such born. Others will follow.
I bid you peace.
YOUR servant and a slave of Christ,
