But the sin was not Eve's that Mary should atone for it.
Sin did not enter the world until Adam ate, not when Eve ate.
The sin was not the first woman's (Eve) that the second woman (Mary) should atone for it. The sin was the first man's (Adam's) that the second man (Jesus) should atone for it.
Jesus' temptation in the wilderness succeeded with His obedience in temptation, where Adam's failed.
Romans 5:12-21 Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned—for sin indeed was in the world before the law was given, but sin is not counted where there is no law. Yet death reigned from Adam to Moses, even over those whose sinning was not like the transgression of Adam, who was a type of the one who was to come.
But the free gift is not like the trespass. For if many died through one man's trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many. And the free gift is not like the result of that one man's sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brought justification. For if, because of one man's trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ.
Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous. Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.
All this extra made up stuff about Mary is nothing more than wishful thinking on the part of Catholics who would love to find ANYTHING to support their errant doctrine about Mary but can't because none of what they put forth about her to deify her can be found in Scripture.
Well...Eve was driven out of the garden along with Adam but the sin trait is said to come thru the male not the females in a spiritual sense. Eve was not sinless; had she been she would have stayed in the garden and Adam driven.
“But the sin was not Eve’s that Mary should atone for it.”
Mary wasn’t atoning for any sin. Do you even know what you’re talking about?
