God is the source of your creation, as well as the source of your salvation. Your parents are the cause of your creation and the Blessed Vigin is the cause of your salvation (S. Irenaeus, Adv. Hacr. III, 22, 4). Without the Blessed Virgin, your mother in the order of grace, you have no salvation. Just as, without your biological mother, you would not be born.
If I understand you correctly, you are saying that since Jesus is my savior and Mary berthed him it necessarily follows that without Mary Jesus would never have been born ergo I would never have had the opportunity to be saved because of this positive correlation.
You may as well say Mary’s parents berthed her so without them, no Mary, then no Jesus, then no salvation. Or Mary’s parents parents etc.; in infinitum in praeteritis…
The problem here I think is your assuming correlation proves causation. A questionable cause logical fallacy. Cum hoc ergo propter hoc -“with this, therefore because of this”- for those who love their latin. In other words, if no Mary; no Jesus. If no Jesus no salvation. The problem there is, as I see it, that Mary is a creature. Created along with everything else by God, for God’s good pleasure.
My parents are no more the cause of my creation than if they were the cause of making only female babies because that’s what they wanted. If I was to be born then I was to be born. Not because they had a conception of who I was to be but because God created a situation in which my berth was to happen. Don’t get me wrong though they serve a very important function. I respect them for loving me, teaching me, caring for my needs and not prematurely ending my life but I don’t revere them for being the arbitrary source of my creation.
Mary in that sense didn’t choose God, God chose to create Mary. Pick any other name you wish they would still be who they were created to be. Because we cling to this idea of free will we must allow for the fact that Mary, however unlikely given the circumstances of her heavenly visitation, could have refused to get pregnant. Though I’m not sure how she would have gone about that? Anyways, if so, then there is no apparent reason why some other creature couldn’t have, indeed they would have, berthed Jesus since that is how God chose it to be in his creation. A son IS born! Not; A son might be born.
It simply would have been a different created reality from the get go. We wouldn’t know it. Perhaps there were many “nos” in other realities which collapsed salvation and with it creation. I don’t know and neither do you I would guess. Our business is dealing with this creation.
Or you may as well say God chose Mary because he knew she would say yes. Mary was told she was blessed because she would give birth. The angel didn’t ask Mary if she would be so kind as to give birth for God. Since when does God ask? He tells it like it is. And so it shall be.
Once again though, i speak from the mind and may be wrong but also from the heart because I fear we raise up a creature to the level of the creator. Make no mistake though, I love Mary as much as I can humanly love my neighbor and no one can tell me I love her less because I attribute less to her, but I also love Christ more.
May God bless your imparted wisdom to me.
