Lu 3:23 And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,
HP: I find no such thing mentioned in these verses. Heli is said to be the father of Joseph, not Mary. He was, just as they supposed. The problem is that they did not understand the process that took place in the conceiving of Jesus by the Holy Spirit.
That's the typical way of reasoning by the people who claim the Biological Motherhood.
I do not rule out the possibility that the Genealogy in Luke be the one for Mary, but there is other possibilities too because of the Bible expression which doesn't mention Mary but Joseph.
That is not very critical question in this discussion as it doesn't fix the Biological motherhood but even Surrogacy could have the genealogy.
When we mention the Surrogacy, the Surrogacy of Mary is unique and different from the usual human surrogacy.
In case of the human surrogacy, it is often a shame caused by the fertility problem etc. However, in this case, Surrogacy is a great honor as it means that Mary received Jesus Christ bodily in her, the sinless person was launched there, and there would be no problem with the Biological Mother as there will be no Bio mother either. Therefore this Surrogacy is absolutely unique and different from all the other Surrogacy.
Therefore it is not a matter about whether Mary takes the honor or not.
The Core issue remains all the time about " Word became Flesh" and about whether the Sin-stricken ovum can produce a spotless, blemish body of Christ for sinless sacrifice or not.
In both reasons, Biological Motherhood is far beyond Biblical Truth.
