What are you, a child? If you make the claim that the sin nature is passed by the father only, you should provide scriptural proof for this.
I don't think you can.
Heloo Winman, getting ready to sign off, but just wanted to throw this out for consideration:
When a man leaves father and mother and clings to his wife, the twain become one, right?
All are the result of this, including Mary. She is the result of a physical union between her father and mother, and is the "one" which resulted from the twain.
In the case of Christ's birth, He is not the result of the twain becoming one, but rather, is the result of God's creating His body in her womb.
This makes it possible for Christ to have a human nature while still retaining His divine nature. He was not the result of natural procreation.
Because of this, it can be said:
Hebrews 7
26For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;
"Separate from sinners."
He is contrasted with the rest of humanity, by us, I am sure you would agree, as well as by the record of scripture.
27Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
All previous High Priests had to offer up sacrifice for themselves, then, for the people. Could we assume that there were among the Gentiles those that did not need to offer up sacrifice?
28For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.
The law set as rulers, or gave the rule, to men that were weak (most probably due to the fact they were sinners and needed to offer up sacrifice for themselves as well), but the word of the oath has made perfect forever the Son.
In many places we see Christ set apart from humanity, though He could, being made of a woman, die in the place of man.
What is that one thing that distinguishes man from every other man that has lived?
God bless.
