Whether or not you believe in the virgin birth, Matt 1:23 says that the angel announced that Mary would “conceive”. Earlier the writer says by “holy spirit” (Matt 1:18).
If the translation is accurate in its use of the word “conceive”, then Mary contributed half of the DNA and the rest was perhaps new DNA. This can only be conjecture as the scriptures do not elaborate on genetic science/engineering.
WTC has long theorized that sin comes through the DNA of the male. They may be right or just twisting the scriptures. Or maybe the hokey pokey really is what it’s all about. Who knows?!
The real question I ask is: Where is the connection to the previous spirit creature that was in heaven prior to his arrival on earth as a human embryo? In transferring the life of Jesus to the womb of Mary, something more than material DNA was surely required. WTC narrative does not allow for a life force to have been transferred - even if they say otherwise. They have never adequately explained the breath of life that God breathed into Adam at creation. They also teach that when a person dies, he ceases to exist entirely. If that is the case, then those resurrected are little more than clever duplicates of the original person since there is no uninterrupted link/connection between the past life and the future life. Would we take comfort in a promise that an identical version of one self will be recreated to live in the future? I certainly would not since it would not be ME.
Please think about this a little while before sending a knee jerk reply supporting WTC theology. This is not a promotion for an immortal soul, but rather a question about the life force itself and the role it plays in making us the individuals that we are, something more than a complex electro-chemical assemblage of DNA. Seriously, take some time to think this over.
