Let us assume for the discussion that I accept God used an ovum from Mary's ovary to conceive Jesus. This would mean Jesus has at minimum, 23 chromosomes from Mary and thus from all whom she is descended, including Adam. The normal human complement of chromosomes is 46, so Jesus also has, at minimum, 23 chromosomes from 'a father' source.
Okay so far? ... The question I would ask of you then is upon which chromosome is the original sin of Adam carried? Since Jesus was without sin, it would appear you need, for insurance, that the chromosome comes through the mother's gene pool, right? So the sinless nature of Mary means she either had such a chromosome and it was 'cured' before she implanted in her mother's womb, or this 'sin chromosome' was cured before she was born. Is this getting a bit too over the top yet? ... In anticipation of your response, allow me to post asecond possible explanation, one no more fantastic than the assumption that Mary was born sinless.
What if the 'sin chromosome' is from the father genetic pool. Could The God Who created the entire Universe and thus all that is in it have take a spermatazoon from Adam before the fall and brought that 23 chromosomes to the scene of Mary's conceiving in her womb? ... Can we answer in any meaningful way just where the spermatazoon came from for the conception of Jesus, if we assume that the ovum came from Mary's ovary?
At this point I would imagine you are in favor of God dividing the ovum of Mary before it separated into two sets of 23, and by miracle God then caused the ovum to become a complete zygote with the sex of the resulting new being as a male. [This is contrary to the result when this happens in nature, that an ovum becomes a zygotic new life without spermatazoon. But for our discussion we will let that slide ... we are going to get to nothing short of the miraculous with this anyway!]
HOWEVER, if you are not willing to go down these various roads of resoning this out, and prefer to just skip to 'it's a miracle' we are still left with the very real possibility that you nor I know just exactly what miraculous thing God did to 'conceive Jesus in Mary's womb. You can declare that half of His chromosomal complement comes from mary, but there is exactly zero Biblical evidence for this ... and we do have a mountain of biological data to suggest other possibilities and still not toss away the reality that God performed a miraculous event to conceive Jesus in Mary's womb.
My dear MHGinTN, I will ignore your evident ire toward me. I am not trying to force a “scientific” explanation of what is plainly called a miracle. On the other hand I am not about to deny the clear testimony of the Holy Scriptures and the equally plain confession of Christendom that Jesus Christ is born of Mary and that Mary is indeed His mother. That simply means what it means in the case of every other mother/son incident, that is, mother and son share genetic material. That is as far as I care to go.
Remember, this was occasioned by your saying, post #51, “Jesus was not genetically a child of Mary,” to which I replied, “Excuse me ... huh?” You have now admitted in the point at which I questioned you that you said more than you should have in saying that Jesus was not genetically a child of Mary. She is His mother. Period. Or the Bible lies.
So, that’s it. I’m done. I was not trying to make the case for her immaculate conception, not at all! But I was defending the historic, Christian faith and the integrity of the Holy Scriptures. Mary is the mother of our Lord, with all that that implies. Period. It is a miracle, the further details of which are, therefore, beyond Scriptural proof and the subject only to our - almost certainly fruitless - speculation. Which is precisely the reason why the Apostle Paul wrote to young pastor Timothy: “And without controversy great is the mystery of godliness: God was manifested in the flesh ...” (1 Timothy 3:16)
