Bread From Heaven: Protestants forget that both Adam and Eve were created without sin. Most of the Angels did not sin and people in Heaven do not sin and that does not make any of them God. So sinlessness is a human trait that God originally bestowed upon human beings. It was also His desire that they remain sinless. Mary is human. Her sinlessness makes her special but not divine in any way. And she is the mother of our Savior she is not a savior.
Comment: The point not taken here is that ALL of the beings you reference, Adam/Eve, angels, people in heaven have the ability to choose sin or not.
Response: That is true, they have free will and so are able to choose to sin or not. But 2/3′s of the angels chose NOT TO SIN. So they are still sinless. The people in Heaven choose NOT TO SIN. So, they are now sinless. Adam & Eve were created without a fallen nature and were therefore NOT DESTINED to sin like the rest of us. Mary also was created without a sin nature and likewise able to choose not to sin by the grace of God. And she, unlike Adam and Eve resisted the temptation to sin her whole life.
Comment:Adam/Eve sinned, angels sinned against God’s will, people in heaven sinned while they were on this earth.
Response: OK, Scripture tells us that Adam, Eve, and some of the Angels sinned. But where in Scripture does it say that Mary sinned? What sin did she commit?
Comment: Mary sinned for she was human.
Response: Where in Scripture does it say that God created human beings to BE SINFUL? Part of their basic nature? Normally human beings die as well as sin. But we were not created originally to DIE. Death entered in after the Fall. Therefore, God did not create us with Death as a required attribute of our human nature. Some people in the OT did not die–Enoch & Elijah. Just because, by the power of God they escaped the experience of death does not somehow make them anything other than human.
Comment: Sinlessness is a trait of God not of humanity,
Response: God is sinless, that is true. But where does it say that ONLY God is sinless? What about the angels who remained loyal to God. They are sinless but they are not Gods.
Comment: You stated how God would have wanted a perfect vessel for his son to be born. If you continue with this logic, than how would God want Mary conceived? Into sinfull parents and then her vessel would not have been pure. And what about her grandparents? And their parents and you can see how this need for perfection grows exponentially which means somewhere in history there is an entire race of sinlesss beings.
Response: We do not teach that Mary’s parent’s were sinless. Mary was a creature. Jesus was God Incarnate. For the God incarnate to dwell in perfect purity in Mary’s womb is more fitting than any necessity for Mary conceived without sin, to dwell in perfect purity. If Mary’s parents had been sinless then she would have received her perfected human nature from them but she received it directly from her Heavenly Father.
Comment: Mary was endowed with grace by God, because she was good, not perfect.
Response: Where might this be found in Scripture? We of course believe Mary was endowed with grace that removed the inherited sin nature and chose to be obedient to God her whole life.
