I've seen people advocate this and find it very bizarre. It is just not credible at all to me that sin is connected organically to the blood only of the father. I think there is no biblical basis for it. Sin is not organic; it is part of our nature. We don't get it through blood but through the sin passed on from Adam which has somehow bent our nature to rebel against God. I don't think it is a material thing.
This smacks of Gnosticism to me as well. It is not the physical body that is the source of sin though the body has reaped the results of sin (illness, death); sin is the whole fallen nature.
Yes, sin is not transferred physically either through your father or mother. Sin is a moral issue, not physical.
I do not believe in original sin. I believe all men are born innocent and become sinners when they knowingly and willingly commit sin (which we all do).
The scriptures numerous times say we are "flesh". Our flesh has many desires and passions, but that in itself is not good or bad. We have an appetite, and that is good, we need to eat to be healthy. But if we go to either extreme, if we deny our appetite, or completely give into it we have health issues.
The same with the sex drive, it is not evil for a man to enjoy looking at his wife and desiring her. It is when a man allows himself to have passions for another woman that problems arise.
As Webdog said, man was created with the ability to do either right or wrong, else Adam and Eve could not have possibly sinned. And we see that besides the serpent's lie, Eve's natural desires seduced her to sin.
Gen 3:6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
Eve's natural desires caused her to be tempted to eat this fruit. It was beautiful and no doubt looked delicious for food. It was desired to make one wise. Up to this time, it was God's word and warning that restrained Adam and Eve from eating this fruit. It was the serpent's lie that seduced her to give in to her natural desires. Satan cannot force us to sin, only tempt us.
And this is exactly how he tempted Jesus. Jesus was a man and so was very hungry after fasting for 40 days. And so Satan always attacks what he perceives as our greatest weakness. But Jesus was able to withstand this temptation.
It was Augustine who taught that sin is passed down physically, but it is false doctrine.
No, we are flesh just like Adam and Eve. The flesh is weak and easily tempted, but this is no excuse for sin.
Matt 26:41 Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak.
James 1:13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
14 But every man is tempted, when he is drawn away of his own lust, and enticed.
15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
We are not tempted because of Adam or our father and mother, but every man is tempted when he is drawn away of his own lust and enticed (which means seduced). And when we sin, sin brings forth death. Therefore death has passed on all men, for that all have sinned.
Rom 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Many falsely teach this verse to say that sin has passed upon all men. That is not what it says. It says "death" has passed on all men for that all have sinned. We spiritually die for our own sin, not Adam's or our parent's.
