What wasn’t understood at the time was the the blood from the mother did not pass to the child. Interesting point that, in this case, the truth of science didn’t catch up to the bible until I don’t know when.
Sounds like you are using a Greek view of ‘blood.’ In Hebraic scripture blood is ‘life.’ Not plasma etc. The life indeed passes to the child from the mother so the theological issue remains. However, the idea that sin is ‘inherited’ is a common problem for both Protestants and Roman Catholics. Two peas in a pod really.
I may not be following all of that...not a scholar by any stretch. I do know the ‘life is in the blood’, and that His blood was shed, a perfect sacrifice, for my sins. The OT gives a good picture of blood sacrifices, even though those sacrifices of blood were not sufficient, just a picture of the one to come (Jesus, not Obama...).
Is not...Besides the blood of Jesus was written in Greek, not Hebrew...
Jesus IS the Last Adam. He is still alive and forever more, as our Great High Priest, making intercession for us before God The Father Almighty.
What did Jesus obtain from Mary during His gestation in her womb? ... [HINT: could Jesus ingest sin with bread or meat when He ate a meal?]
Jesus was CONCEIVED by The Holy SPirit in Mary's womb. This does not in any biological sense mean Jesus was made from mary any more than eating meat or drinking water or wine or milk 'makes' any part of you.
