BB,You’re overreaching . If there was no DNA in Christ that came from Mary than Christ would not be fully man
This assumes the Old Sin Nature is derived in part from the female chromosomes, whereas many in the last 50 years have held a different view, that the Scriptural record indicates sin is passed from the male chromosomes.
This is consistent with the Scriptural position that the first sin charged to the human race for our death is attributed to Adam, rather than Eve, and also is consistent with our Savior as the Second Adam, through whom we all might have salvation.
SFA, you're overreacting. Reread my post. I said that Mary's DNA was present in the ovum.
