I believe early theologians struggled with Jesus' humanity. The blood sacrifice by Jesus had to be pure, unblemished, spotless, sinless - you name it. How could this be, when, he was born of a woman?
The solution was to make the woman extra-special. Her blood had to be as clean as his needed to be. Thru theology, they solved the problem of the perfect sacrifice. They didn't understand the science involved - mom's blood is not given to the baby. My understanding about blood types and such is that their blood could actually be deadly to one another.
An incredible solution to an incredible theological problem, but then, several hundreds of years later, we find out the science of blood and the incredible miracle of conception. Amazing. Yet God knew all along. Jesus could be born of a woman with sin, yet not have that stain.
We all struggle with things we don't completely understand. We use theology to explain the mysteries of God, trying to understand him the best we can. We serve a great and mighty God, and I know I don't understand all his ways. But I am learning to trust him, for there is none other that is 'good'.
Even that doesn't really fix it, though; it just shifts the perceived 'problem' back one generation.
It's not a problem for me in the first place, since I reject the concept of original sin. So yeah, both Mary and Jesus were born without sin, but so was I and so were you.
Well, if Mary’s blood had to be clean and pure so Jesus blood was clean and pure, how did Mary be born of a sinful mother? Would not Mary’s mother’s blood had to have been pure and clean so that Mary’s would have been, and so on back?
Now if God could do that kind of miracle for Mary so that she was born of a sinful mother sinless herself (presuming that to be the case), then why couldn’t God have done the same thing for Jesus that Catholics claim He did for Mary?
Do you understand where the sin nature comes from anyway?
