HP: The manner in which conception takes place does not determine 'what' is conceived. I have more than enough farmer in me to know that with certainty.
What kind of gobblygook is this? The manner does determine "what" is conceived because what was conceived required the Holy Spirit involved in the manner it was conceived! If conception had not been by this "manner" then "what" was conceived may only be human without any divinity!
Moreover, what was conceived require the intervention of God in order to "prepare a body" that was sacrficially legal under law (heb. 10:5). Sacrifice under law had to be "without blemish" to be legal for sacrifice!
You cannot deny that Adam prior to the fall was 100% human can you?
You cannot deny that Adam after the fall was still 100% human can you?
Therefore you cannot assert that Hebrews 2;17 requires anything more than Christ was "made" 100% human can you??
Therefore the absence or presence of sin does not change human nature to be something other than human nature does it?
However, it is the human father that passes "death" IN THE BODY to the children rather than the mother:
17 Now then it is no more I that do it, but sin that dwelleth in me.
18 For I know that in me (that is, in my flesh,) dwelleth no good thing:
20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
Sin indwelling the body of Paul is called "This body OF DEATH" demonstrating that when "death" is passed down from the father to children in the body so is sin because "death by sin" - "By one man's offence MANY BE DEAD."
If your theory is correct then why did God have to provide Christ with a special body that was fit under sacrificial law????
Heb. 10:5 Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:
