I will give you a different answer that i am certain pilgrim will not like, But i will be very interested to see what you think of it Ed?
KJV 'And it came to pass, when he had made an end of speaking unto Saul, that the soul of Jonathan was knit with the soul of David, and Jonathan loved him as his own soul'
The text seems to me have a plain and obvious meaning of two souls intertwined. Not one 'flesh'.mark 10 8. How can this be?
KJV Eph 2 6 'And hath raised us up together, and made us sit together in heavenly places in Christ Jesus'

This seems to be talking about sitting together (Paul and others) and past tense in heavenly places in Christ while they are still alive on Earth. How can this be?

Here is the bit you will not like i think, you are about to be taken out of your comfort box so hold on to your hat!.

Kat Kerr has revealed that as we are made 'in his image'- a body, spirit and soul to parallel Jesus, God the Father and The Holy Spirit respectively. The Holy Spirit being made of an infinite number of layers-explaining in part his omnipresence- and He deposits one of these in us at salvation . But our soul too in 'in His iamge' and is likewise made with sometimes many but not infinite layers. She describes as having seen it and likens it to looking like a vertically opened book with pages fanning out and each apge looking like us. She has specifically quoted this Eph 2:6 verse.
She says that at salvation Jesus as well as giving us a 'layer' of Himself takes a layer from us and sits it in Heaven.

Also, when in a deep relationship with someone we may 'give' a layer of our soul to them.(wife/husband or friend)and them likewise to us, She uses this to explain why some people just can not let go of even violent relationships.

A simple elegant plain text literal answer, no homosexuality described or condoned, souls intertwined not one flesh. One flesh just between married men and women.
Kerr has certainly got my attention
