Share your thoughts, brother.
I alluded to this earlier, but I thought I'd touch on one more thing regarding the salutation from the angel. In Luke 1:28 the angel does not refer to Mary by her name, but instead greets her as "full of grace" (kecharitomene). In this way it appears that God's messenger considers "full of grace" to be Mary's name. This reminds me of when God provides Abram with a new name meaning "Father of Nations" and Jesus calling Simon, "Peter" aka the Rock. When God gives people new names he is emphasizing their character & the role they have to play in salvation history. Anyways, just thought I'd throw that out there since I knew there were a few more things you wanted to touch on.
Thank you for sharing that with me. I am eager to continue learning, and you have a good point about the way God applies meaningful names to people throughout Scripture. By the way, I also looked at that chart you gave me showing the OT and NT comparisons related to Mary; I think my knowledge of this particular typology is pretty limited, so I was amazed to see so many clear connections. To me, it's exciting to see all the different ways parts of the Bible relate to one another, because those deep connections further show the impossibility that anyone but God could have created it.
So, here's something that came to my mind. I know it's an imperfect illustration, but I started thinking about science and genetics. We receive half of our chromosomes, containing genes, from our mother and half from our father. The way that original sin is passed from generation to generation is similar to genes being passed along. It is simply a part of us that is inherited just like our hair color and so on.
Progressing down that line, Jesus, who is fully man and fully God, inherited His human side from his mother, Mary. So, what prevented his human nature from inheriting sin, as we know He was completely sinless? Obviously, His birth itself was miraculous, and it seems there was a further miracle in place to allow Him to be born into the line of humanity with a fresh start basically. So, either God would have saved Mary ahead of time to prevent the original sin from continuing through her, or He prevented Jesus in some other way from inheriting it before He was conceived.
I think when you take this in combination with the idea that only a pure vessel would be able to carry the Living Word, the Catholic view of Mary is completely logical. It doesn't take away from what Christ did on the cross when you say that Mary simply received grace before she was even conceived; this is baffling to the human mind, because our minds are small, but we must remember that nothing is beyond God's abilities. I'm not saying that I've formed my opinion one way or the other on the Immaculate Conception, just that there is a lot of logic, seemingly well-supported by Scripture, to indicate the possibility of this event.
