God created Jesus by himself, there was no mother or wife involved. Mary is NOT divine, she is human. She has NO special influence on Christ WHATSOEVER. She is not omniscient or omnipresent, so how can she hear millions of prayers at once? ABSOLUTLEY NO ONE is above sin, except God. She is only a vessel (or an instrument, if you like) that helped bring Christ into the world in human form. She has ABSOLUTLEY NO influence in our salvation whatsoever. Jesus is the ONLY meditator between man and God. Period.
I’m from a Southern Baptist (fundamentalist) background, and of all the things Marian doctrine was the most difficult for me to understand. I really read and prayed about it, and the more I learned and prayed I started to see the parts of scripture that were either unexplained or left out by my Baptist faith.
So, on Marian doctrine, here’s how I understand it:
There are some words that are easy to get hung up on, and mediation is one of them. (BTW, a few other words: trinity, rapture, divinity…are not even in the Bible, yet we know and accept the roles they play in worship.) Any time anyone plays “middle-man”, they’re a mediator. If I ask you to pray for me, and you do, you have put yourself in the position of mediator. I expect that you will pray to God for me…right? That’s what Mary and the Saints do. We do not expect that they have god-like power to grant wishes. Because they are “fully alive in Christ”, they are not dead, they are living in Heaven and pray to God on our behalf…just like those living here on Earth do for us. God wants us to pray for each other, and the Bible says that “the prayers of a righteous man availeth”, and those in Heaven are pretty righteous, since nothing unclean can enter Heaven. Our praying for each other does not detract from Jesus’ role as mediator, because all prayer goes through Him.
People in Heaven don’t live and age like we do here on Earth. Time does not matter, doesn’t restrict, and doesn’t limit once we’re there. If time doesn’t exist, isn’t that like being omnipresent? (Not speaking from anything I’ve been taught by the Church, just thinking…) …on the same note as God being omnipresent; if he knew Mary would consent to being a vessel, and that Jesus would die for the sins of those who came before and after him…why is it impossible to believe that he would make her “full of grace” from the beginning, knowing what he did? Mary was not above sin, she just got the “cash up front”

so that Jesus could be born of a pure vessel. Does that make sense?
When Mary presented Jesus in the temple : Luke 2:34-35, "Then Simeon blessed them and said to Mary,
his mother: “This child is destined to cause the falling and rising of many in Israel, and to be a sign that will be spoken against, so that the thoughts of many hearts will be revealed. And a sword will pierce your own soul too.” That verse is telling Mary that she was destined to suffer as well, no? Any mother would hate to see her child treated that way, so why would it be important to point it out?..unless it was meant to emphasize the importance of their relationship. Her suffering was part of His, and that’s a belief that can be read literally, sola scriptura.
Just like there are fanatics in the Protestant denominations (WBC, for example), there are fanatics in Catholicism. Some take it too far, and literally worship Mary like a diety. She is not. Catholicism does not teach that, and does not condone it. We do respect her, though, because Jesus named her Mother, and made a point to see to it that she was labeled as such when he was suffering on the cross.
